LP Series Low Pressure Desalination RO Membrane

Product Description:

LP series low pressure desalination RO membrane is polyamide composite membrane to be used for ground and underground water desalination. It is featured with low pressure running, high water production capacity and good desalination. Under relatively low operation pressure, it can reach same high water flow and high desalination as normal low pressure membrane. Its operative pressure is 2/3 of normal low pressure composite membrane and desalination rate can reach 99.5%. It is applicable to the desalination treatment of ground water, underground water and tap water with salt content below 2000ppm. 

8” RO membrane is mainly used for pure water and boiler feeding water production in medium to large scaled chemical factory, pharmaceutical factory, food factory, electrical factory and power generation plant, as well as the desalination and purification of municipal used water. 

4” RO membrane is mainly used for pure water and ultrapure water production in small scaled pharmaceutical factory, food factory, electrical factory, as well as the desalination and purification of water supply stations at schools and communities. 

2.5” RO membrane is mainly used for pure water production of small commercial pure water machines like those in hospitals and labs.
