Domestic 97% Desalination 50g Reverse Osmosis Water Purifier Parts RO Membrane

Characteristics of reverse osmosis membrane technology: this equipment has the advantages of compact structure, small floor area, low water production per unit volume, low energy consumption, etc., and has been applied in almost all industries. Without camouflage, it relies on the pressure greater than the osmotic pressure to drain the desalted water through the membrane capillarity. It also has the membrane screening function, which can remove very small bacteria and viruses.

The reverse osmosis membrane should have the following characteristics:

(1) high-efficiency salt rejection at high flow rates;

(2) high mechanical strength and service life;

(3) able to function at lower operating pressures;

(4) capable of Resistant to chemical or biochemical effects;

(5) It is less affected by factors such as pH value and temperature;

(6) The source of film-making raw materials is easy, the processing is simple, and low cost.
