Product Introduction
Oxidation-resistant reverse osmosis membrane element
Oxidation-resistant reverse osmosis membrane element is suitable for desalination and TOC removal of oxidizing aqueous solution, especially for purification of high-concentration hydrogen peroxide. The membrane element has the characteristics of high TOC and boron removal rate and can be used in the preparation process of electronic-grade hydrogen peroxide.
