TML20-370 low pollution reverse osmosis membrance components, with effective membrance area of 370 squre feet. It’s applied for the desalination of bitter water with saltness lower than 10000ppm, surface water and industrial wastewater. Because it’s membrance has the feature of electric neutrality, so it dramatically reduced the absorbtion of bacteria and microorganism on the membrance surface. The maximum width of feed water flow channel not only have strong pollution resistance, also benefits for effective recovery after chemical cleanout. Mainly applied for many kinds of desalination fields such as recycle of municipal sewage and industrial wastewater, desalination of micropollution surface water, boiler feedwater of power station, reuse of cooling cycle wastewater.
