Commercial 4021 Low Pressure Water Filter Water Treatment for Industrial RO Membrane
First, the low-pressure reverse osmosis membrane requires lower feed water pressure, which greatly reduces the investment cost of water pump-related equipment, thereby reducing the cost of membrane elements. Low-pressure RO can maintain a high desalination rate and reduce the operating pressure of membrane elements.
Second, it can effectively prevent secondary pollution. Low pressure reverse osmosis membrane and ultra-low pressure reverse osmosis membrane have larger specific surface area, lower working pressure, more water production and higher desalination rate than cellulose acetate membrane. and desalination rate, resulting in significant savings in system operating costs and capital investment. Low pressure reverse osmosis membranes retain all the advantages of reverse osmosis membranes. Excellent chemical stability. Low pressure reverse osmosis membrane is an ideal reverse osmosis membrane for preparing high-purity water. Compared with the traditional reverse osmosis membrane, the low pressure reverse osmosis membrane has the same high salt rejection rate and high pressure at low pressure, and the water flux has a neutral surface potential and high hydrophilicity, so it has a high antifouling ability. Due to the surface-active substances, it is very suitable for the treatment of wastewater containing impurities.
