陶氏反滲透膜LC LE 4040技術(shù)原理是滲透的一種反向遷移運(yùn)動(dòng)，它主要是在壓力推動(dòng)下，借助半透膜的截留作用，迫使溶液中的溶劑與溶質(zhì)分開(kāi)。溶液濃度越高，滲透壓值越大。在反滲透過(guò)程中所要施加的壓力，在系統(tǒng)和膜強(qiáng)度允許的范圍內(nèi)，必需遠(yuǎn)大于溶液滲透壓值，一般為滲透壓值的幾倍到近幾十倍。當(dāng)鹽的水溶液與多孔的半透膜表面接觸時(shí)，則在膜的溶液界面上選擇吸附一層水分子，在反滲透壓力的作用下，通過(guò)膜的毛細(xì)管作用流出純水。并連續(xù)地流出形成界面純水層。

陶氏反滲透膜LC LE 4040分離對(duì)象是溶解的離子和分子量幾百以上的有機(jī)物，能透過(guò)溶劑而不能透過(guò)溶質(zhì)的膜一般稱之為理想的半透膜。當(dāng)把溶劑和溶液分別置于此膜的兩側(cè)時(shí)，純?nèi)軇⒆匀淮┻^(guò)半透膜而自發(fā)地向溶液一側(cè)流動(dòng)。這種現(xiàn)象叫滲透。當(dāng)滲透過(guò)程進(jìn)行到溶液的液面產(chǎn)生一個(gè)壓力，溶劑向溶液方向流動(dòng)的趨勢(shì)，即達(dá)到平衡，此壓力稱為該溶液的滲透壓。
