Oxidation Resistant RO Element

Oxidation Resistant RO Element has the characteristics of low pressure in operation, high permeate flow and excellent performance.By applying the special synthesis process, the antioxidant properties of membrane components have been enhanced, enable it to withstand the impact of a certain amount of oxidant substances, thus simplified and optimized the pretreatment of RO system.The process reduces bio-pollution of membrane element, saves operation cost and extends the service life.
