東麗RO膜TML20D-400 8英寸低壓化學耐久性反滲透膜元件 是采用最新的材料及生產技術的一款高脫鹽率、高產水量、耐化學清洗的膜元 件。
有效膜面積為400平方英尺，給水流道34mil， 適合于含鹽量約10000ppm以下的給水， 有較嚴格的預處理、但給水中仍含有有機物等污染物的領域。由于其膜片呈電中性，這大大 減少了細菌、微生物在膜表面的吸附；最寬的34mil給水流道，使其不僅有較強的抗污染性， 更具有化學清洗后的有效恢復性。
TML20D-400具有最寬泛的清洗pH值范圍（pH1~13）， 可以快速有效的解決膜元件的污染問題；反滲透膜片能夠承受一定范圍內，由于操作失誤等 原因造成的輕微余氯泄露事故，提高了系統的安全性。
