日本東麗TM720D-400反滲透膜元件 性能特點(diǎn)：
TM720D-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。
TM720D-400有效膜面積為400 平方英尺，給水流道34mil。適合于含鹽量10000ppm 以下的苦咸水淡化，以及微污染地表水的脫鹽、冷卻循環(huán)排污水的回用等各種應(yīng)用領(lǐng)域。
TM720D-400是目前擁有高產(chǎn)水量，高脫鹽率的苦咸水膜元件；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(nèi)，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(tǒng)的安全性。
