　　TML20N-400low pollution reverse osmosis

　　I. Summary

　　TML20N-400 low pollution membrane reverse osmosis component, efficient membrane area is 400 square foot, the width of feedwater channel is 34mil. It is suitable for the brackish water and surface water and industrial waste water desalinization of less than 10000 ppm salt content, which is the special use of strict pretreatment system. Because the membrane displays electric neutrality, which can reduce the adsorption of bacteria and microorganisms, the most wide feedwater channel is 34mil, which has the strong anti-pollution, which is more beneficial to the restorement after chemical cleaning.
