225 Psi Large Flux Brackish Water Membrane 8040 Sewage Wastewater Treatment Membrane
225 psi Low Fouling Brackish Water 8040 RO Membrane for Wastewater Treatment
Keensen Low Fouling series products are aromatic polyamide reverse osmosis membrane element with anti-fouling property used in complicated influent condition. This series membrane adopts special process technology to improve the hydrophilicity, charge characteristic and surface smoothness, and reduces the growth and adsorption of pollutants and surface microorganisms in products running. FR membrane element adopts 34mil wide channel spacer for easy cleaning, and also helps to reduce fouling and pressure difference of membrane system and maintain a longer lifespan.
It mainly used for reclaimed water, reused water, waste water, reverse osmosis concentrated water treatment, etc.within salinity<10000mg/L. The application fields include electricity, metallurgy, steel, chemical industry, textile and dyeing,municipal sewage etc. It has the characteristics of high- desalination, good restorative after cleaning and low pressure drop (the pressure gap between the feedwater and concentrated water ).
