    反滲透(tou)制(zhi)備純化水(shui)是(shi)一(yi)種(zhong)常用(yong)的水(shui)(shui)處理技(ji)術，可以用(yong)于(yu)制備純(chun)化水(shui)(shui)。反(fan)滲(shen)(shen)(shen)透(tou)技(ji)術利(li)用(yong)半透(tou)膜，將水(shui)(shui)從低(di)濃(nong)(nong)度(du)(du)一(yi)側(ce)向高濃(nong)(nong)度(du)(du)一(yi)側(ce)滲(shen)(shen)(shen)透(tou)，直到兩種(zhong)溶(rong)(rong)液(ye)的滲(shen)(shen)(shen)透(tou)壓達到平衡。反(fan)滲(shen)(shen)(shen)透(tou)可以去除(chu)水(shui)(shui)中的溶(rong)(rong)解鹽類、有機(ji)物、微生物等雜質，得到較(jiao)為純(chun)凈的水(shui)(shui)。在反(fan)滲(shen)(shen)(shen)透(tou)膜組(zu)件中，水(shui)(shui)分(fen)子(zi)(zi)在壓力的作用(yong)下(xia)通過(guo)半透(tou)膜，而(er)離子(zi)(zi)、分(fen)子(zi)(zi)和大分(fen)子(zi)(zi)則被截(jie)留下(xia)來(lai)，從而(er)實現(xian)溶(rong)(rong)劑(ji)和溶(rong)(rong)質的分(fen)離。
