Engineered with advanced polyamide technology, it achieves an exceptional 98.5% contaminant rejection rate while operating at significantly lower pressures than conventional membranes, reducing energy consumption and system costs. Ideal for diverse water sources including surface and underground water, this membrane is a top-tier choice for professional-grade water purification in industrial, food processing, and pharmaceutical settings. ## Description The ULP series of ultra-low-pressure polyamide compound membrane elements are newly developed by Vontron Membrane Technology Co., Ltd. Working under the conditions of ultra-low operating pressure, ULP membrane series can achieve as high permeated flow and rejection rate as regular low-pressure membranes can, it runs under approximately two thirds pressure of that regular low pressure compound membranes, and can achieve a rejection rate of as high as 98%. It is applicable to desalination of surface water and underground water. It operates under approximately two thirds of the operating pressure of regular low-pressure composite membranes, which can decrease the investment costs for additional facilities such as: pumps, pipelines, containers and the operating cost for the RO system, thus increasing the economic efficiency. Applicable to desalination treatment of those water sources with NaCl lower than 2000 ppm, such as surface water, underground water, tap water and municipal water. ULP series membrane elements are mainly applicable to applications such as window cleaning, aquatic use, foodstuff processing, and pharmaceutical production.
