SINOMEMB® series fouling resistant (SNBW-FR) membrane elements are made of fouling resistant membrane and widened feed conduit (34mil-56mil, customized according to customer's working conditions). The membrane surface is more smooth and hydrophilic, and the membrane charge is closer to electric neutral, which can destroy the foundation of fouling and organic pollution blockage.The membrane element has stronger ability to resist inorganic salt scaling and colloid and organic pollution, which greatly improves the cleaning and recovery performance of the membrane, broadens the application field of the membrane element and to the greatest extent prolongs the service life of the membrane element.The system can still maintain a low pressure drop,high durability, high removal rate and high water yield even under high pollution conditions,make this series of Brackish water RO membrane elements superior throughout its life cycle.
FR series products are aromatic polyamide reverse osmosis membrane element with anti-fouling property used in complex 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 highdesalination, good restorative after cleaning and low pressure drop (the pressure gap between the feedwater and concentrated water ).
