ENERGY CONSERVATION REVERSE OSMOSIS MEMBRANE ELEMENT

JK Energy Conservation (EC) series adopt new membrane process, with membrane surface layer having hydrophilic modification. On the premise of not changing the desalting ability, permeable ability is greatly increased under low pressure operation, water flux of unit membrane area the same with the other high pressure running products of the company. The automatic coiling technology highly improved the effective membrane area of membrane element and further improved the water flux, this series of products by increasing the membrane area and changing the way of the combination of membrane hydrophilic to increase the water flux of membrane element, and keep the water flux a balance, rather than a destructive limit to increase water flux of membrane, and therefore, the series of membrane element can keep the low rate of fouling, so as to maintain high yield for a long time, slow attenuation. That makes a series of EC membrane element with a low energy consumption, high yield and water flux stability, membrane element characteristics of long service life, less available of membrane element number to meet the water flux requirement, reduce the investment.
