ULP aromatic poly-amide composite elements is specially developed for groundwater and surface water treatment. The operating pressure is about 2/3 of the conventional low-pressure brackish water membranes and the rejection rate can reach 99.5%. With higher salt rejection rate, it can also meet the required permeate flow at very low operating pressure.
It mainly applies to treatment for surface water, groundwater, municipal water, etc. within salinity<2000mg/L. The application fields include bottled drinking water, dual water supply in residential area or industrial park, food and beverage production, etc. It has the characteristics of higher permeate flow, low operating pressure as well as high rejection rate.
