东丽膜TML20D-400

日本东丽TML20D-400反渗透RO膜元件 性能特点：

东丽TML20D-400 8英寸低压化学耐久性反渗透膜元件是采用较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**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；较宽的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具有较宽泛的清洗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。
