alkaline water purifier vs ro

RO water purifier accessories: faucet, pressure bucket, water pipe, joint (ball valve), casing, Deng Yuan pump, PP filter, activated carbon filter, RO membrane, wastewater ratio, check valve, high pressure switch, low pressure switch, etc.

RO water purifier water purification process

The raw water enters the first three-stage filter element of the RO water purifier through the water pipe for initial filtration, and then the water is pressurized by the booster pump to let the water flow in the RO reverse osmosis membrane, and the water source is finely purified by the reverse osmosis effect of the RO membrane. To the pressure tank, it is kept by the pressure tank.

When it is needed, open the pressure barrel ball valve, press the pressure tank to let the water flow into the last small T33 filter element (exquisite activated carbon filter, mainly to purify the water quality), and then output clean water through the gooseneck faucet.

RO reverse osmosis technology principle

RO reverse osmosis technology is the most effective treatment technology for filtering heavy metals.

The principle of reverse osmosis is to apply a pressure greater than the pressure on one side of the raw water to reversely infiltrate the water molecules from the higher concentration to the lower concentration. Since the pores of reverse osmosis are much smaller than several hundred times or even thousands of times of case poisons and bacteria, various viruses, bacteria, heavy metals, solid solubles, and contaminated organic matter cannot pass through the RO reverse osmosis membrane, thereby purifying the water quality. purpose.

Why is it called ‘reverse osmosis’ filtering?

When the same volume of dilute solution (such as fresh water) and concentrated solution (such as salt water) are placed on both sides of the semipermeable membrane, the solvent in the dilute solution will naturally pass through the semipermeable membrane and spontaneously flow to the side of the concentrated solution. This phenomenon is called infiltration.

When the permeation reaches equilibrium, the liquid level on the concentrated solution side will be higher than the liquid level of the dilute solution, that is, a pressure difference is formed, and the pressure difference is the osmotic pressure.

If a pressure greater than the osmotic pressure is applied to the concentrated solution side, the flow direction of the solvent will be opposite to the original permeation direction, and the flow from the concentrated solution to the dilute solution side begins. This process is called reverse osmosis.

Simply put, by energizing, applying pressure to the concentrated solution, changing the original direction of penetration, and realizing the countercurrent of the concentrated solution, thereby purifying the concentrated solution and producing pure water.
