Secondary water supply into a safe soft rib of drinking water: qualified at the factory Not qualified at home Examples are as follows: 1 At present, most urban communities need to build their own storage and pressurization facilities to introduce water from public water supply networks into thousands of households. This process is called secondary water supply. However, some local public water supply pipes are qualified for water, and water problems that enter the community and flow out of the user’s faucet frequently occur. Secondary water supply is becoming a weak link in the safety of urban drinking water.
2 Amazing scene! Shenzhen woman taking a shower from the shower Red live insect
Bathing at home is a beautiful thing, but the recent bathing has become a nightmare for Ms. Zhong and her family. On December 27, Ms. Zhong, who lives in Century Square in Nanshan District, Shenzhen, told reporters that she found many showers bursting out of red bugs during bathing. It is reported that the cause of the red bug appears or appears in the water pipe. The water pipe in the community has been a cast iron water pipe for nearly 20 years. The water pipe is rusty and damaged, so there may be impurities and insects in the water pipe.
3 “High-end” bottled water was actually filtered for tap water. Sale of fake barrels of water
Tap water disguised as a high-end bottled water for profiteering. Recently, Songjiang police cracked a case of counterfeiting famous branded bottled water. After investigation, it was found that the production and management environment of the fake dens was bad. The suspects filtered the tap water through a simple filter device purchased by himself and directly filled it into an empty bucket without any disinfection and affixed with a counterfeit trademark. The barrel is packaged by a machine, and the entire process of making a fake can be completed in just a few minutes.
Hainan Daily Bacteria exceed the standard bottled water into a healthy stealth killer
Drinking unqualified, expired or unclean bottled water can cause various diseases, which can cause discomfort, dizziness, diarrhea or nausea, which can cause serious poisoning. Not long ago, some schools in Haining and Haiyan, Zhejiang Province, had symptoms such as nausea, vomiting and diarrhea. The number of reported cases reached more than 500. Tested by the local CDC, it is determined to be Norovirus infection. The student’s infection with Norovirus was mainly caused by drinking bottled water produced using deep water wells.
In the process of transporting tap water to various households, water quality is difficult to be ensured due to corrosion of water pipelines, pipeline ablation, pipe network leakage, secondary water supply, etc.; the bottled water on the market is mixed, the quality is worrying, and some still use tap water. Installed. Moreover, the bottled water must be consumed within a certain period of time (recommended within one week). The more the period is exceeded, the more bacterial microbes are regenerated and the water quality is difficult to be guaranteed.
You believe, or don’t believe Unclean drinking water will affect the body’s health
Many people may feel that drinking water for so many years has not seen any problems, but the harm of unclean drinking water to the body is long-term accumulation, and it is too late to find it.
The harm caused by unclean drinking water has two major characteristics: First, it is gradual. All kinds of toxic substances slowly accumulate in the human body to cause harm, which takes a long time, so it is not easy to detect and more concealed. Second, it is not easy to decompose and accumulate. Organic poisons and all heavy metals are generally not decomposed and metabolized. Once they enter the human body, they will only stay for a long time and accumulate.
In addition to changing the filter, the water purifier can be left alone?
The maintenance of the water purifier should firstly change the filter element at regular intervals, otherwise… The filtration effect is weakened and the water quality is deteriorated. The adsorption capacity of the filter element is saturated. The plugging of the filter element will not only reduce the amount of water but also reduce the filtration effect. If the water in this state continues to drink, it will affect the health of the body. The filter element is damaged step by step, filter life is shortened The water purifier is generally filtered step by step by a multi-stage filter. If the primary filter element is blocked, large particles of impurities such as sediment and rust in the water will directly enter the second-stage filter element, so that the filter element that is not responsible for filtering impurities is overloaded, resulting in early retirement. You only need to lose two or more filter cartridges because of the bad habit of “changing the filter cartridge from time to time”. Water purifier life is also affected The loss of the filter element can be more than the damage of the filter element: just because the filter element is the core component of the best cheap water purifier, it is as if the heart and lung function of the person is not strong enough, the operation of the whole machine will become dull, such a machine is very fast. Will also “end to sleep.”
For those who are often on a business trip or returning from a trip, the best indoor water purifiers in the home will always be ruthlessly into the “cold palace”, from one or two weeks to more than a year and a half. However, the water purifier has not been operated for a long time, and if it is not treated properly, it may cause secondary pollution to the water quality. Therefore, before using, be sure to use the following correct method to “activate” again~ 1. When using again, rinse the water purifier first. The water purifier is deactivated for a long time. When it is used again, it needs to be rinsed first: it is not used for about 3 days, and it is washed for 3-5 minutes; if it is more than 10 days, it needs to be washed for 15 minutes; if it is more than one month or even longer Use, the inside of the filter may breed bacteria and mold, in order to avoid secondary pollution, it is recommended to thoroughly clean the filter once.
2, after a long time to stop water, you must first discharge If water is stopped for a long time, after the water supply is restored, a large amount of sediment, rust, and other substances will be deposited in the water pipe. At this time, the water purifier will be used again. It is necessary to open the sewage outlet and remove the sediment and rust inside to avoid water purification. The device is clogged, does not have water or water, has an odor, and even shortens the life of the filter. 3. If necessary, backwashing If the water purifier is not used for more than one month, the inside of the filter element of the water purifier will breed bacteria. It is recommended to thoroughly clean the filter element when using it again. If the water quality still appears to be poor, it is recommended to backwash the water purifier. After the water purifier is backwashed, the contaminants in the water will be discharged from the drain outlet with direct flushing. 4, half a year, it is recommended to replace the filter If it is not used for 3-6 months or longer, consider replacing the filter element. Because it will not be used for a long time, some filter elements will lose the filtering function, such as ultrafiltration membrane drying and pore size shrinkage. Moreover, the ultrafiltration membrane cannot be recovered, which will cause the water in the water purifier to become smaller or even fail. If this happens, the filter cartridge needs to be replaced. (You can clean the filter element first, then test the water purification effect, and then decide whether you need to replace the filter element according to the purification effect)
5. If you need to go out, you can close the tap water inlet valve in advance. If you are going to travel or do not use the water purifier for a long time, be sure to close the inlet valve of tap water and do a good job of a power failure and water cut. In order to avoid the uninformed situation, because the water pressure is too large, the faucet will fall off and cause a water increase event, resulting in unnecessary losses. In addition, the water purifier that is not used for a long time needs to drain the water into the machine. At the same time, the outdoor water purifier needs to turn off the ball valve and drain the water from the whole machine and the filter bottle to avoid freezing the machine due to the cold weather.
In addition to the normal life cycle of the water purifier, if the machine can be durable, it is still inseparable from daily maintenance: 1. When using the machine for the first time, the filter element inside the water purifier must be flushed to wash off the protective liquid in the filter element. The specific operation is as follows: open the tap water inlet ball valve, tap water tap, purify the tap, and then frequently switch the tap (for example, off for 3 seconds, 8 seconds) to form a pulsed impact for 15 minutes until the water is clear and free of foam. 2, need to be cleaned regularly, the product will be used for a certain period of time, there will be impurities accumulation, filter plugging and so on. When the water output is less than half of the original, it means that the water purifier filter has been blocked more seriously, and the filter can be flushed (many models have a flush button on the control panel, long press for three seconds). 3, do not expose to the sun and cold, it is important to emphasize that the water purifier is not suitable for outdoor installation, because whether it is higher in the summer outdoor temperature, it is easy to age under the sun exposure, or the temperature in the winter is too low, the internal waterway will freeze, Damage to the water purifier. And, no matter which kind of water treatment machine, it may breed blue algae under high temperatures and sunlight. Therefore, the water purifier is suitable for installation in a cool place indoors, not too close to the heat source. 4. The water pressure of the tap water should be stable. If the water pressure suddenly becomes too small, the water hammer phenomenon will occur. If the pressure is too large, it will easily damage the internal components of the water purifier. Therefore, the water purifier can be pre-installed before the water purifier is installed. Valves, in the case of going out or not using the water purifier for a short time, you need to close the inlet valve to protect the water purifier from water pressure, which can extend the life of the water purifier.
First, the water on the high floor is not clean Due to insufficient water supply pressure in the municipal pipe network, only 5-6 floors of water supply can be achieved. That is to say, the water supply above the sixth floor can only use the secondary water supply and pressure equipment to achieve the purpose of water supply. The secondary water supply, the pollution is more serious, the impurities are too much, it is not clean, and it is not suitable for long-term drinking. If you have water purification equipment, the water quality will be clean no matter how high the floor is.
Second, the inconvenience brought by the water dispenser Drinkers are used in general households, but there are three problems with drinking fountains: 1, the water dispenser should always change the water, trouble; 2, the water dispenser should be cleaned frequently, otherwise, it will easily breed bacteria; 3, the water dispenser must be kept energized all the year-round, power consumption. If you have household water purification equipment, you can solve the above three problems well.
Third, the safety risks of tap water If you have an electric kettle in your home, you will find that there are scales after burning a few times. Why? Tap water is too many impurities and is not clean.
If you wake up in the morning and brush your teeth with tap water, you will find that the tap water that you just opened will be a bit yellow or even pungent. Why? Tap water is too many impurities and is not clean.
If you are a tea lover, then the water you are sure to use is mineral water, purified water or filtered water. Why? Tap water is too many impurities and is not clean.
If you are a maintenance-conscious person, you must know that in addition to exercising more, focusing on sleep quality and nutrition, drinking water is also very important. You will definitely not drink tap water. Why? Tap water is too many impurities and not clean?
If there are elderly people and children in the family, it is not recommended to drink tap water for a long time, which is easy to cause stones and gastrointestinal diseases. Why? In addition to the poor stomach of the elderly and children, there is a lot of impurities in the tap water, not clean.
2 How much water do we need per day? The Chinese Dietary Guidelines state that healthy adults need about 2,500 ml of water a day. Adults living and exercising in mild climates are advised to drink at least 1200 ml per day, about 6 cups. If the amount of activity is large and sweating is more, increase the amount of drinking water and replenish water in time.
3 The healthy and good water that the human body can drink for a long time should have the following requirements:
4 What kind of water can we choose?
Linlin’s various kinds of water are dazzling, but they are not healthy and good for long-term drinking.
Pure water is purified by distillation, reverse osmosis and other technologies to remove raw materials. While removing harmful substances, it also removes almost all trace elements and minerals beneficial to the human body, so it is not suitable for long-term drinking.
Mineral water Most of the trace elements and minerals in mineral water should be said to be needed by the human body. However, studies have shown that not all types and amounts of trace elements and minerals contained in mineral water are suitable for all people, so it is not suitable for long-term drinking.
Beverages “Bai Boshui has no taste, or drink it.” Many children have cola and fruity drinks that don’t leave their hands every day. Drinking water with drinks is tantamount to spending money to buy problems. This does not help the body to replenish water, but also reduces appetite, affecting digestion and absorption.
Bottled water Bucket containing bottled water will be recycled and reused over a long period of time, which can easily cause fungal infections. The hygiene conditions of those manufacturers who are not regular are more difficult to guarantee.
Bottled water is easy to carry, open and drink, and bottled water is favored by more and more consumers. However, the PET bottles used in bottled water often contain substances that may cause chronic poisoning in the human body, especially when the bottle is in a high-temperature environment (if someone likes to have a bottle of water in the car), or does not drink it in time after opening. Harmful substances can seep into the water, and long-term drinking will endanger health.
5 The current pollution situation of water sources is more severe
The “State of the Environment Bulletin 2013” shows that 9.0% of the country’s top ten water systems are inferior, and nearly 60% of the national groundwater is not up to standard, and wastewater discharge is 69.54 billion tons…
River 9.0% water is inferior V In 2013, China’s top ten water sources continued to suffer from various types of pollution. The Yangtze River, the Yellow River, the Pearl River, the Songhua River, the Huaihe River, the Haihe River, the Liaohe River, the Zhejiang-Zhejiang River, the Northwest Rivers and the Southwest Rivers are the top ten river basins within the geographical range of China. The Ministry of Environmental Protection’s “2013 China Environmental Status Bulletin” shows that in the top ten basins, the IV~V category is 19.3%, while the proportion of the inferior V water quality section is 9.0%. The water quality of the top ten water systems is not optimistic. Surface water is divided into five categories according to function: high, low: I, II, III, IV, V; the poor V water is the water whose pollution level has exceeded V, which means the pollution is the most serious.
Nearly 60% of groundwater is not up to standard If the surface water system is polluted, can the groundwater escape? The authoritative data of the Ministry of Environmental Protection shows that the pollution of groundwater is more worrying than the pollution of surface rivers. In 2013, groundwater quality monitoring was carried out in 198 prefecture-level administrative regions across the country. The total number of monitoring points was 4,778, including 800 national monitoring points. According to the “Groundwater Quality Standards” (GB/T14848-93), the comprehensive monitoring results show that the water quality is excellent level of monitoring points only 10.4% of all monitoring points; while the water quality is poorly monitored points accounted for 43.9%; the water quality is very poor The level of monitoring points accounted for 15.7%. That is to say, in the municipal-level administrative districts where groundwater quality monitoring is carried out, nearly 60% of the groundwater is not up to standard. Groundwater pollution is generally slow, difficult to find and difficult to manage. Once the groundwater is contaminated, it will take more than a decade or even decades to restore the water quality even if it is completely eliminated.
Annual wastewater discharge of 69.54 billion tons Water pollution is so serious that excessive pollutant emissions are the main culprit. In 2013, the total discharge of wastewater in the country was 69.54 billion tons, and the total discharge of chemical oxygen demand was 23.527 million tons. That is to say, if calculated according to the population of 1.3 billion, each person will face nearly 53 tons of wastewater discharge. These wastewater discharges come mainly from industrial sources, sources of life, and agricultural sources. Industrial pollution is the most important source of pollution for surface water.
6 water treatment technology of waterworks needs to be improved
Water from the water source must be treated by the waterworks before entering the home. Generally speaking, urban drinking water is mainly based on conventional water treatment technology, and surface water source adopts a coagulation-precipitation-filtration-disinfection water treatment process, and groundwater source is directly disinfected after being cleaned without purification process. The conventional treatment process is mainly aimed at removing turbidity, color, and microorganisms in water, and it is difficult to completely solve the problems of organic pollution, algae pollution, heavy metals such as lead and mercury which are prominent in current urban water sources.
At present, most urban water plants in China use liquid chlorine disinfection, and the action of chlorine with chlorine in the subsequent disinfection process will produce carcinogens such as organic halogenated hydrocarbons and various harmful by-products. It can be seen that the clean water treatment process needs to be improved, the pollutants cannot be effectively removed during the purification process, and even new pollutants may be introduced, which threatens the safety of urban drinking water.
7 water supply pipe network aging leads to secondary pollution
The urban water supply network system is a huge and complex project. Water from the water plant to the user needs to be transported over long distances. The residence time in the pipe network sometimes lasts for several days, and the pipe network has a great influence on the water quality. At present, the water supply network of the city, especially the old city, is generally corrosive and aging due to its long service life. The pipe network with a service life of more than 50 years accounts for 6% of the total. In recent years, the leakage of the pipe network has generally increased.
At present, the urban drinking water transportation system is mainly based on the transmission of the string network. Due to factors such as the material of the pipe material, the age of the pipe network, and the nature of the disinfectant itself, the water quality will have some changes during the water delivery process, accounting for 42.4% of the total national water supply. The survey results of cities show that the turbidity, chroma, and iron indicators have different degrees of deterioration compared with the factory water. The turbidity of the factory water is 1.3 degrees, and the pipe network water is increased to 1.6 degrees; Increased from 5.2 degrees to 6.7 degrees; iron increased from 0.09 mg/L to 0.11 mg/L.
8 Is your faucet qualified?
In addition to pipe network equipment, the last hidden danger of drinking water safety is hidden in the last ring of tap water. In order to reduce the cost of electroplating, some enterprises do not have good treatment of the surface such as rust removal before the lead-containing faucet is electroplated, resulting in poor surface corrosion resistance. Under normal circumstances, the quality of the electroplated faucet will not cause pollution, mainly because the surface of the electroplated coating will be oxidized quickly when it comes into contact with air, resulting in a protective film, but the use of unqualified faucets, water can lead The protective film falls off and invades the water, causing the precipitation of lead elements in the water nozzle, and the “overnight water” lead metal content retained in the faucet nozzle is higher. In addition, some companies now use copper processing to reduce costs, the lead content in the faucet is high, and the possibility of lead precipitation during use is greater.
9 Hazards of pathogenic microorganisms and pollutants in water to human health:
Therefore, the purchase of household water purifiers as a barrier to the safety of household drinking water is an effective way to control the risk of drinking water. At present, the penetration rate of household water purifiers in China is only 2%, and the penetration rate in developed countries has reached 70%1. At the time of purchase, it is recommended to consider the filter technology of the water purifier first, which affects whether the filtered water produced by the filter can be consumed for a long time, meets the requirements of healthy and good water, whether it is water-saving and environmentally friendly; , smart, security, brand reputation and other aspects of performance, in line with these requirements, the big brand home water purifier can be assured of choice.
Little knowledge of clean water: the function and function of common water purifier filter on the market
People care about domestic water, and water purifiers become one of the essential home appliances in family life. At present, there are many kinds of water purifiers on the market, and the filter elements used are also various. We can’t know how to clean the water quality of the ordinary consumer water purifier. Here is a brief introduction to how the water purifier can purify the water. The water purifier relies on the internal filter element to filter impurities and pollutants in the water. It is the core component of the water purifier. At present, the water purifier filter element mainly includes PP cotton, activated carbon, ultrafiltration membrane or reverse osmosis membrane.
PP cotton The first-stage filter element of the cheap and best water purifier mainly intercepts and filters the water-insoluble suspended matter, sediment, red worm, rust, colloid and the like. As the foremost filter element, it can protect the rear filter element. Due to the front-end filtration, the filter loss is faster. It usually needs to be replaced in about 3 months.
Activated carbon Activated carbon is generally made of coal-based carbon or plant carbon (coconut shell, nutshell). After carbonization and activation treatment, it produces a developed pore structure and has a strong filtration and adsorption effect. In water purification products, activated carbon is mainly used to remove the odor of water and remove residual chlorine. At the same time, it has some functions to filter heavy metal ions, but it is weak. Due to the wide variety of impurities contained in tap water, in theory, activated carbon can adsorb some of the inorganic and organic substances, including some colloids. However, this will cause the activated carbon to quickly fail, so the activated carbon is often not used as the first-stage filter element, and PP cotton is added in front.
Ultrafiltration membrane The ultrafiltration membrane is a mechanical sieve membrane with an accuracy of typically 0.01 microns. At this level, most of the impurities can be filtered out, and some heavy metal ions and minerals in the water cannot be filtered. Therefore, in general, the water filtered by the ultrafiltration membrane cannot be directly consumed. However, in the southern part of the water quality, the filtered water of the ultrafiltration membrane has reached the requirement of direct drinking. Reverse osmosis membrane The reverse osmosis membrane is the mainstream product of the water purification equipment filter on the market. Under the action of a certain pressure, the reverse osmosis membrane can pass water molecules and other impurities will be trapped. Therefore, the water filtered by the reverse osmosis membrane is basically pure water. Therefore, people often use reverse osmosis water purification equipment. It is called a straight drink machine. Regarding the flux of the reverse osmosis membrane, 50G, 75G or 400G is generally common. For example, 50G means that the film is continuously operated for 24 hours, and the amount of pure water produced is 50 gallons, which is 189L. At present, reverse osmosis water purification equipment of less than 200G generally has a water storage tank.
In addition, the disadvantage of reverse osmosis is that the wastewater ratio is relatively large relative to its “net” advantage in purifying water quality. Of course, we can make rational use of it and solve the problem of waste.

Is the weather in your home now blowing air conditioners or air conditioners? Although the autumn has passed yesterday, it seems that the “cool autumn” seems to be far away~~~ In the hot summer, the best “beverage” is cool and white, but under high-temperature conditions, drinking water is undergoing subtle changes all the time, invisible, but there are health threats. Therefore, installing a water purifier at home is a guarantee for water safety. The current water purifier industry has developed rapidly in recent years, and the water purifier branding market has gradually formed. The water purifier products are diversified and diverse. So how do you buy a water purifier?
Key point 1: According to the water quality of the area The Ministry of Ecology and Environment notified the state of surface water environmental quality in December 2018.
The water quality is excellent (I to VIII), the proportion of the section is 74.2%, and the proportion of the inferior V section is 7.1%; The proportions of the Yangtze River, the Yellow River, the Pearl River, the Songhua River, the Huaihe River, the Haihe River, the Liaohe River, the Zhuhe River in the northwest, the Zhuhe River in the northwest, the Zhuhe River in the southwest, and the Zhejing Plate in the southwest are excellent in water quality (I to VIII), which is 74.3%, up 2.5 percentage points year-on-year; The proportion of the V-type section was 6.9%, a decrease of 1.5 percentage points year-on-year. The main pollution indicators are chemical oxygen demand, ammonia nitrogen, and total phosphorus. Among the 111 key lakes (libraries) monitored, the water quality was excellent (I～III), the lake bank accounted for 66.7%, up 4.2% year-on-year; the inferior V water quality accounted for 8.1%, down 2.6 percentage points year-on-year. The main pollution indicators are total phosphorus, chemical oxygen demand, and permanganate index. – Ministry of Ecology and Environment
It can be seen that the water quality varies greatly from region to region, so the conditions for choosing a water purifier are also very different. In some places, water quality conditions are very good. At this time, a simple ultrafiltration water purifier is used, and the problem is generally not big. However, in areas with poor water quality, the ultrafiltration household water purifier appears to be stretched and cannot achieve the desired results. At this time, a reverse osmosis water purifier is needed. In addition, the general water quality in the northern region is relatively hard. It is recommended to install a water softener to soften the water!
Key point 2: filter type and water purification material At present, the mainstream filter elements on the market are PP cotton filter, activated carbon filter, ultrafiltration membrane, and RO membrane. PP cotton filter mainly used to remove coarser particulate impurities in water; Activated carbon filter element with the multi-pore surface, mainly used for adsorbing water, odor, residual chlorine and organic chemicals in water; Ultrafiltration membrane with a filtration precision of 0.01 micron can effectively remove harmful substances such as sediment, rust, suspended solids, microorganisms, bacteria, viruses, rust and macromolecular organic substances in water; RO membrane (also known as reverse osmosis membrane) is mainly used to remove all harmful substances such as pesticides, bacteria, viruses, heavy metals and ions in water. RO membrane filtration precision can reach 0.0001 microns. One thing to note is that the water purifier level is not as good as possible. The key point is that the material is reliable. The effectiveness of clean water is in principle determined by raw materials and production processes. A water purifier that does not meet the standard quality will not only fail to purify the water but may even cause pollution due to the material falling off.
Why do urban and rural areas need to install water purifiers?
All kinds of information on the Internet can be transmitted to all corners of the world, but you have been concerned about “water and health”? Water pollution incidents occur frequently, can you feel shocked? Maybe, we are not numb, reading these reports, seeing these pictures, there will be more or fewer thoughts in my heart. Below, let’s see why it is necessary to install an Olansi best water purifier in urban and rural areas!
In modern society, people are gradually neglecting some problems because they are busy with work. The first thing that is first is health. Health is very, very important to us. As the saying goes, “The body is the capital of the revolution.” Without health, nothing can be done. To have a healthy body, water is vital. More than 70% of the human body is water, so water is very important. And in our lives, we often overlook the issue of drinking water health.
Let’s talk about the countryside first. Nowadays, there is no running water in most parts of rural areas. It is a well that can be seen everywhere in the countryside. The era of “drinking water and not forgetting to dig wells” is not over. Some old peasants said, “I have been drinking well water for a lifetime, and there is no problem with my body.” In fact, this is only a minority.
We know that well water is a little infiltration of water from the soil. Then, we will not say the content of sediment in the water. In response to this problem, many villagers will throw alum into the well water to achieve the purpose of water purification. In fact, this method has long since become obsolete. Alum clean water can only remove most of the impurities such as sediment, and it is not really removed. It just makes the particles smaller than the dirt and other impurities. Just sinking in the bottom of the water. Moreover, the pollutants in the water are not just these, bacteria, viruses still exist. Therefore, the well water seems to be clean and cool, but it is actually the dirtiest.
In the bustling city, it should be said that it is already a “barrel of the world” situation. Bottled water has already entered thousands of households, so what is the problem behind this seemingly clean bottled water?
First of all, the bottled water you buy is not necessarily true. The occurrence of the “fake water” incident is not once or twice, so this issue should be taken seriously. Second, the bottled water is connected to the water dispenser and is not sealed. After the bottled water is opened, it is best to drink it within three days. After a long time, it will be infected by bacteria and viruses in the air, and the water quality will drop. But in our daily life, we drink a bucket of water for half a month, so It is also unfavorable to the human body.
To solve the problem of drinking water, household water purifiers are undoubtedly the best choice. The water from the water purifier can be directly consumed. The mystery is that the water purifier is like a barrier, which isolates the harmful sediment, rust, solid suspended matter, bacteria, and viruses. It can be said that it is really meaningful. Clean water on it.
What should you pay attention to when installing a water purifier at home?
With the increasing attention to drinking water health issues and the pursuit of healthy living quality, more and more people are aware of the importance of installing a water purifier to protect the health of family drinking water. However, only the scientific installation of the Olansi water purifier can extend the service life based on its function. 1
What should I pay attention to when installing the water purifier?
01 Reserve power lines in advance Currently, the water purifiers favored by consumers on the market are ultrafiltration water purifiers and reverse osmosis water purifiers. Ultrafiltration water purifiers do not need to be energized, but reverse osmosis water purifiers need to be powered. If you are not sure which water purifier to install, it is recommended to reserve the power supply circuit of the water purifier before the decoration, so as to avoid the need to take the bright-line when installing the reverse osmosis water purifier, which will damage the decoration. In addition, the circuit of the water purifier must be separated from other home appliances in the home, because if the water purifier leaks, it will affect other household appliances.
02 Reserve enough space under the cupboard In order to make the kitchen tidier, most people choose to install the water purifier under the cupboard. Therefore, if you want to install a water purifier at home, you should plan the space under the cabinet in advance to reserve enough space for the water purifier. In addition, many reverse osmosis water purifiers will carry a pressure tank. This pressure tank is actually a water storage tank, so when space is reserved, not only space is reserved for the host! If the space under the cupboard is small, don’t worry, the Franny reverse osmosis water purifier FLN-100G-09Plus breaks the installation pattern under the cabinet, and the platform and wall mount are installed, which saves space and adds artistic style to the kitchen.
Three installation methods to meet multiple needs
03 The installation location is critical The choice of the installation position of the water purifier is very important. Generally, the water purifier should be installed close to the water source and the location of the main water, such as near the kitchen pool and near the sink. In addition, the position of the water purifier should not be too dark. If it is installed in the cabinet, it is recommended to install the bulb under the cabinet. The switch is placed in a convenient position for easy operation. In addition, the installation of the water purifier in the north should be selected in the indoor insulation, so as to avoid the temperature is too low to affect the machine water.
04 It is not appropriate to install the location to remember Most of the water purifiers and filter elements are made of plastic, so the water purifier should not be installed close to the heat source, such as the gas stove. If the water purifier is installed close to the heat source, it will easily cause the plastic to decompose and cause pollution. In addition, the water purifier should not be installed outdoors, and the water purifier should be placed outdoors for a long time, which makes the plastic shell of the water purifier brittle and shortens the service life of the water purifier. In addition, the water purifier needs to replace the filter element regularly, so the water purifier installation should not be chosen in a small space because the space is too small, it will be very troublesome to replace the filter element.
Tips: After the installation of the water purifier is completed, the total inlet ball valve should be opened to debug the water purifier to observe whether the joint is leaking. The observation time is about two hours.
After we purchase the water purifier, we will encounter some minor problems during the use. Recently, many customers have called to ask if the water purifier does not produce water or the water is very low. So, today, I will teach you some knowledge about the household water purifiers that do not have water. I hope to help everyone.
The machine itself is faulty: no matter what device, it is very normal to have problems after using it for a long time. Household water purifiers will directly affect the machine’s clean water if internal parts or malfunctions, or other internal parts are damaged. For example, water quality is turbid, water is very small, and even water is not a common thing. Solution: When we use it for half a year, it is best to check and maintain the internal parts of the machine every 2-3 months, which is responsible for the health of our drinking water. And inspection and maintenance can extend the life of the machine and internal parts. This will ensure the water output and water quality of the product.
The water of the water purifier consists of water inlets, water pipes, filters, if this is the first time the water is not used, but the installation order of the water inlet and the water and pipes is wrong, the solution: the faucet, then the water purifier Installation specifications; if there is no water or less water after a period of use, it may be the cause of the blockage of the pipe or the filter is clogged. Solution: Pipe blockage directly removes the blocked part or replaces the new water pipe; the filter blockage will filter out and replace the new filter for direct use.
Check the pipeline of the water purifier, straighten out the water purifier pipeline; check the water purifier power supply, turn on the water purifier 220V AC, if the water purifier input power is normal, check the transformer output voltage; check the high voltage switch or float switch Whether it is malfunctioning, can’t jump back; check if the water inlet solenoid valve is normal. Unscrew the solenoid valve outlet, turn on the power, check whether the water is flowing, if it does not pass water, turn to the next test; open the original water ball valve to check whether the filter element is blocked before the reverse osmosis membrane, such as blockage; if the water is passed, the solenoid valve is damaged. Check if the pressure after the booster pump has reached the required pressure. If it is lower than 0.3MPa, it needs to be replaced; open the reverse osmosis membrane pure water port, if there is no water, the reverse osmosis membrane is damaged; check whether the wastewater discharge is too large, so that the ratio of pure and wastewater is out of balance; check whether the activated carbon filter element is clogged.
With the deepening of industrialization, there are more and more pollutants in rivers. Tap water is taken from rivers and rivers, and some pollution is inevitable. Nowadays more and more families choose to install water purifiers to solve tap water. Water quality problems. So, what is the working principle of water purifier filtration?
Water filter filtration uses a filter element and is a physical filtration process. It separates water molecules from other impurities through the size of the grid on the filter element. Water purifiers generally have a variety of filter elements, each of which has a different impurity. Filter elements such as PP cotton activated carbon, as well as ultrafiltration membrane, reverse osmosis RO membrane, and other types.
First level: PP cotton PP cotton is mainly made of rust, sediment and other large particles from the water. The large particles are isolated on the outside through the filter holes on the PP cotton. Second stage: granular activated carbon Granular activated carbon has an adsorption function, can adsorb residual chlorine in tap water, remove the odor of tap water, and can also absorb color substances and restore the thoroughness of tap water.
Third stage: compressed activated carbon Compressed activated carbon and granular activated carbon work the same, but the effect is better. 1. Compressed activated carbon particles are fine, using hair hole technology, the diameter is tortuous, which greatly prolongs the contact time between water and activated carbon during use; 2. The decolorization effect of compressed activated carbon is good; 3. Compressed activated carbon has high precision and more abundant filtration, and the water outlet is ensured; 4. Compressed activated carbon filtration accuracy can be controlled; 5. Compressed activated carbon is more environmentally friendly. Compressed activated carbon filtration precision controllable Small class Then there are small partners to ask since compressed activated carbon has more advantages than granular activated carbon, why our water purifiers do not directly contain compressed activated carbon, why should we install granular activated carbon? This involves the rationality of the water treatment process. First of all, if the activated carbon in the water purifier is replaced by compressed activated carbon, the water discharge efficiency may be reduced by at least half on the existing basis. Secondly, water purification is a step-by-step filtration process, so multi-stage filtration is required. Eliminate pollutants in water; finally, the cost of granular activated carbon is lower than that of compressed activated carbon.
Fourth stage: RO film The RO membrane filters all of the above impurities and is mainly used to filter heavy metals in tap water because of its smallest pores. At this point, almost all of the pollutants in the tap water are filtered and can be directly consumed. Granule
Level 5: Rear activated carbon (T33) Using the adsorption principle of activated carbon, it can effectively remove residual chlorine, toxic and harmful substances in water, and improve water quality and taste.
