Industrial RO membrane elements

La description

1 Domestic membrane elements The ****-sized and ****-sized domestic membrane elements are mainly applicable to various small-sized systems, such as household water purifier and other water purifying devices in hospital and laboratory, which are EM-RO*******0, EM-RO********0, EM-NF*******0 and EM-NF********0. 2.2.2 Industrial RO membrane elements ●ULP Series: Ultra-low Pressure RO Membrane Elements Working under the conditions of ultra low operating pressure, ULP membrane series can achieve as high permeated flow and rejection rate as regular low-pressure membranes can. Its testing pressure is approximately 1 MPa, and can achieve a NaCl rejection rate of as high as *9.0%. The ULP series products contain ****-sized, ****-sized, ****-sized, ****-sized and ****-sized. ●LP Series: Low Pressure RO Membrane Element With the operation of low-pressure, high permeated flow and excellent desalination, LP series is mainly applicable to brackish water desalination. Furthermore, with the excellent properties in rejecting soluble salts, TOC and SiO2, it is particularly applicable to preparation of high-purity water for electronic and electrical power industries. ●FR Series: Fouling Resistant RO Membrane Element The ****-sized and ****-sized FR membrane series is mainly applied to reuse of wastewater and treatment of high polluted surface water. For treatment of water with inferior quality grade, it adopts the design of wider feed inflow conduit net, which makes it easier to be cleaned. Furthermore, the membrane surface has been specially processed with special technology, thus changing the electric charge and the smoothness of membrane surface, increasing the hydrophilicity of membrane surface, reducing the contaminants and microbes adhering to the membrane surface, bringing about the performance of stronger resistant to scaling, organic contamination and microbe contamination, and therefore decreasing the fouling speed of membrane element and elongating its service life. ●HOR Series: High Oxidation Resistant RO Membrane Element The ****-sized and ****-sized HOR series, independently developed E-MEM Co., Ltd. upon years of research, is mainly applied to treatment of wastewater reuse, surface water with high microbe contamination, and feed containing oxidative substances as well as applied to germ-free system, etc. Considering the shortcoming of regular polyamide RO membrane in weak resistance to oxidation, with special materials, the HOR series has integrated special synthetic process to strengthen the oxidation resistance of membrane element. The use of HOR membrane elements can simplify and optimize the pretreatment process of RO system, save the investment cost and elongate the service life.
