Membrane permeation element is characterized by low pressure operation, high water production and good desalination performance. It can realize the same high water content flow rate and high desalination rate as the conventional low-pressure membrane under low operating pressure. Its working pressure is about 2/3 of the working pressure of conventional low-pressure composite membrane, which can be used in surface water, groundwater and municipal water supply system with salt content below 2000 parts per batch.

The 2.5-inch desalination membrane is mainly used in small commercial water purifiers, hospitals and laboratory water purifiers. The 4-inch seawater desalination membrane is mainly applied to the small-scale treatment of pure water and high temperature water used in the fields of medicine, food, electronics, etc. It can also be used for the desalination and treatment of seawater in the water supply stations such as schools. The seawater desalination membrane is mainly applied to the large and medium-sized chemical industry, pharmacy, foodstuffs, electronics factories, pure water treatment, boiler water, etc., and it can be used for the desalination and purification of the municipal water as well.
