HOR Series is the oxidation-resistant polyamide membrane element independently developed by VONTRON. Aiming to overcome the shortcoming of low oxidation resistance commonly existing in traditional polyamide RO membrane, it utilizes unique applies specialized synthesizing process to strengthen the oxidation resistance of membrane element, allowing the disinfectants to be directly added into the on-line elements, thus achieving the complete asepsis of RO mainbody.
