Chemical and PetrochemicalOverview of Pure Water in Chemical and Petrochemical Industries In the petrochemical and chemical industries, water treatment equipment that is both cost-effective and capable of meeting users' specific process water requirements can be produced through different combinations of production processes such as reverse osmosis, ion exchange, and EDI, tailored to the users' specific water quality demands. Commonly employed processes can be categorized into ion exchange systems, reverse osmosis systems, and reverse osmosis + EDI electrodeionization systems. Water used in the petrochemical and chemical industries primarily includes water for concentration, separation, purification, and water distribution equipment in chemical processes, desalinated and softened boiler makeup water, as well as production water for industries such as papermaking, electroplating, and printing and dyeing.
