Reverse osmosis membrane is the core component to achieve reverse osmosis. It is an artificial semi -semi -diaphragm made of simulated biological semi -diaphragm. Generally made of polymer materials. Such as acetate cellulose film, aromatic polybacchide membrane, and aromatherapy. The diameter of the micropores on the surface is generally between 0.5 and 10nm, and through the size of sex, the chemical structure of the membrane itself. Some polymer materials have good exclusion of salt, and the water through the water is not good. Some polymer material chemical structures have more hydrophilic groups, so the water through the water is relatively fast. Therefore, a satisfactory reverse osmosis membrane should have an appropriate infiltration or dehydration rate.
The reverse osmosis membrane should have the following characteristics:
(1) It should have an efficient salinity rate at a high current;
(2) Has high mechanical strength and service life;
(3) Can play the function under low operation pressure;
(4) The impact of chemical or biochemical effects;
(5) It is less affected by factors such as pH value, temperature and other factors;
(6) The source of the diaphragm is easy, easy to process, and low cost.
The structure of reverse osmosis membrane has two types: asymmetric membrane and average film. The current membrane material is mainly used for cubin and aromatic polyamide.
Its components include hollow fiber, rolling, plate frame and tube.
It can be used to operate chemical unit operations such as separation, concentration, and purification, and is mainly used in pure water preparation and water treatment industry.
We have a Thai customers who basically order the reverse osmosis membrane once in three months. He is mainly used to filter fresh water. He said that the effect was very good and he would continue to repurchase.
