The FRP membrane housing adopts epoxy resin and fiber material after special process treatment, with good corrosion resistance, excellent temperature resistance, pressure resistance and wear resistance, these characteristics make the membrane housing can maintain safety and stability in the long-term use process. The reverse osmosis process needs to be carried out under high pressure, and the FRP membrane housing can withstand pressures of up to 2,000 psi, thus ensuring the normal operation of the RO membrane elements. FRP membrane housing has good insulation properties, which can effectively isolate the influence of external temperature on the membrane. Because of these characteristics, we can use it to compose equipment for civil and industrial water treatment, such as seawater desalination, wastewater treatment and drinking water purification and other fields.
