性能特点：
东丽RO膜TML20D-400 8英寸低压化学耐久性反渗透膜元件 是采用最新的材料及生产技术的一款高脱盐率、高产水量、耐化学清洗的膜元 件。
有效膜面积为400平方英尺，给水流道34mil， 适合于含盐量约10000ppm以下的给水， 有较严格的预处理、但给水中仍含有有机物等污染物的领域。由于其膜片呈电中性，这大大 减少了细菌、微生物在膜表面的吸附；最宽的34mil给水流道，使其不仅有较强的抗污染性， 更具有化学清洗后的有效恢复性。
TML20D-400具有最宽泛的清洗pH值范围（pH1~13）， 可以快速有效的解决膜元件的污染问题；反渗透膜片能够承受一定范围内，由于操作失误等 原因造成的轻微余氯泄露事故，提高了系统的安全性。
