日本東麗反滲透膜

性能特點(diǎn)

日本東麗TML20D-400反滲透RO膜元件 性能特點(diǎn):

東麗RO膜TML20D-400 8英寸低壓化學(xué)耐久性反滲透膜元件 是采用新的材料及生產(chǎn)技術(shù)的一款高脫鹽率、高產(chǎn)水量、耐化學(xué)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(lǐng)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;寬的34mil給水流道,使其不僅有較強的抗污染性, 更具有化學(xué)清洗后的有效恢復性。

TML20D-400具有寬泛的清洗pH值范圍(pH1~13), 可以快速有效的解決膜元件的污染問(wèn)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。
