XLE – Extra Low Energy BWRO Membranes

By changing membrane surface and chemical properties, and upgrading the formulation and production conditions for both the supporting layer and thin film composite layer, IonClear™ XLE Series RO membrane offer enlarged specific surface area and hydrophilicity to maximize permeate flux rate. It is applicable for municipal waste water treatment, and it is one of the membrane elements with the highest water flux and lowest operating pressure. The total cost of the system with this element is the low, therefore it can significantly improve overall operating economy of the membrane system. As the latest RO membrane element with extra-low energy consumption and high performance, its operating pressure is about 1/2 less than regular BW RO membrane elements, and the rejection rate can reach 99%
