LP Industrial Reverse Osmosis Membrane Element
LP (Low Pressure) series is an aromatic polyamide composite membrane element for desalination of brackish water, featuring low operating pressure, high water yield and high desalination rate. It has a high removal rate of dissolved salts, TOC, SiO2 and other substances, and is especially suitable for the preparation of high purity water in the electronics and electric power industries.
LP series membrane elements are suitable for desalination of surface water, groundwater, tap water and municipal water with salt content below 10,000ppm, and are mainly used in various scales of industrial pure water, power plant boiler make-up water and other fields, as well as in the field of brackish water applications such as high-concentration saline wastewater and beverage water manufacturing.
