Reverse Osmosis

Reverse osmosis (RO) systems are designed to deliver a reliable supply of high purity water for your production or process. Impurities carried by influent can build up on membrane surfaces decreasing system efficiency and impacting permeate quality. Water containing suspended solids, dissolved minerals and microorganisms all contribute to this problem.  Chemtex offers a complete line of reverse osmosis treatment chemicals to help you combat membrane fouling and scaling problems:
