Main uses and characteristics of Toray reverse osmosis membrane

The main separation object of Toray reverse osmosis membrane technology is to separate the ion range in the solution. Reverse osmosis separation process does not need heating, has no phase change, has the advantages of less energy consumption, small equipment size, simple operation, strong adaptability and wide application range, and has become one of the important water treatment means.

Reverse osmosis membrane separation technology is a practical water treatment technology. Reverse osmosis is a fine filtration system at present. RO membrane can block all solutes and inorganic molecules and any organic matter with molecular weight greater than 100. Water molecules can be purified freely through R0 membrane, and the desalination rate of dissolved salt can reach 95% or even 99%. Therefore, reverse osmosis is widely used. Toray reverse osmosis membrane is gradually used for desalination of seawater and brackish water, as well as the manufacture of domestic drinking water and industrial pure water.

Basic principle and characteristics of Dongli reverse osmosis membrane

When fresh water and salt water are separated by a semipermeable membrane that can only penetrate water but not solute, fresh water will naturally penetrate the semipermeable membrane to the salt water side, which is called osmosis. When the water level on the brine side reaches a certain height, pressure is generated, thus preventing fresh water from further infiltrating into the brine side. If a pressure greater than osmotic pressure is applied to the brine side, the water in the brine will reach the fresh water side through the semi-permeable membrane from the brine side, which is called reverse osmosis.
