Reverse Osmosis membrane is to spend hundreds of millions of dollars and after years of carefully developed in high-tech water procession technology. This kind of film separation technology, it is to rely on through the film under the pressure of the solvent solution and the process of the solute separation. Penetration is a physical phenomenon and the membranes can work under ultra low pressure to reach as high permeate flow and salt rejection as regular low pressure composite membrane, and achieves a salt rejection rate of up to at least 97%, which can decrease the investment costs for such relevant facilities as pump, piping, and container etc, and operating cost for the RO system, thus increasing the economic efficiency.
ULP series low pressure desalination reverse osmosis membrane components are polyamide composite membranes developed by our company for surface water groundwater.
ULP
They have the characteristics of low pressure operation, high water yield and good desalination performance.
It can achieve the same high water flux and high desalination rate under lower operating pressure than conventional low-pressure membrane.
It's operating pressure is around two thirds of the operating pressure of conventional low-pressure composite membrane, and the desalination rate can reach99.5%.
99.5%.
It can be used to treat surface water, groundwater and tap water with salinity less than 2000 ppm.
2000ppm,.
Among them, 8 inch desalination membrane is mainly used for desalination and purification of large and medium-sized chemical,pharmaceutical, food, power plant, process water for electronic plant, boiler supply water, and municipal water.
4 Inch desalination membrane is mainly used in small-scale pharmaceutical, food, electronic factory process water, ultra-pure water, etc.
It can also be used in desalination purification treatment in schools, communities and other water supply stations.
Among them, 2.5 inch desalination membrane is mainly used in small commercial water purifiers, hospitals and laboratory water purifiers.
