ULP (Ultra Low Pressure) series are ultra-low pressure aromatic polyamide composite membrane components Vontron latest research and development for surface water and groundwater desalination, and conventional low pressure membranes can achieve the same in the ultra-low operating pressure conditions high water flux and high rejection rate. Low pressure is about to run its regular operating pressure of 2/3 composite membrane desalination rate of 99.5%. Thereby reducing investment costs and operating costs associated with reverse osmosis system pumps, piping, vessels and other equipment to improve economic efficiency. ULP series desalination membrane elements for the salinity of about 2000ppm below surface water, groundwater, water and municipal water, water is mainly used in a variety of sizes of pure water, boiler feed water, food processing and pharmaceutical manufacturing industry and other kinds of fields.
