The most critical issue in treating industrial process water using GWT Reverse Osmosis technology is pretreatment. The process water source chemistry will determine the appropriate pretreatment technology to be used.

Prior to considering reverse osmosis in an industrial process water application, a complete water analysis is required. Using this analysis, we can evaluate the best treatment approach. After analyzing the clients water analysis, GWT determines the specific optimal pretreatment technologies to be used prior to the RO system to minimize operating costs and maximize the production of high quality treated water. Elevated levels of calcium, magnesium or silica can contribute to RO membrane fouling, and will need to be handled by appropriate anti-scalant chemicals.

In many process water applications, using a GWT reverse osmosis system can reduce operating cost by providing high quality water for ingredient water, cooling tower water, or boiler feed water.
