High Permeate thicker feed spacer Brackish Water fouling resistance Reverse Osmosis membrane 4" Elements
Aromatic polyamide composite Fouling Resistant brackish water series of RO reverse osmosis membrane element with anti-fouling property used in complex influent condition. This series membrane adopts special processtechnology to improve the hydrophilicity, charge characteristic and surface smoothness, andreduces the growth and adsorption of pollutants and surface microorganisms in products runningFR membrane element adopts 34mil wide channel spacer for easy cleaning, and also helps toreduce 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 watertreatment, etc.within salinity<10000mg/L. The application fields include electricity, metallurgy, steel.chemical industry, textile and dyeing, municipal sewage etc. lt has the characteristics of high.desalination, good restorative after cleaning and low pressure drop (the pressure gap between thefeedwater and concentrated water ).
