反(fan)(fan)滲(shen)透(tou)水(shui)處(chu)理設(she)(she)(she)備(bei)通常由原水(shui)預處(chu)理系(xi)統、反(fan)(fan)滲(shen)透(tou)純化系(xi)統、超純化后處(chu)理系(xi)統三部分(fen)組成。反(fan)(fan)滲(shen)透(tou)設(she)(she)(she)備(bei)是(shi)水(shui)處(chu)理設(she)(she)(she)備(bei)中經常用(yong)的(de)一個系(xi)統。為(wei)了(le)減輕反(fan)(fan)滲(shen)透(tou)設(she)(she)(she)備(bei)的(de)工作壓力和正(zheng)常運(yun)行(xing)(xing)，反(fan)(fan)滲(shen)透(tou)設(she)(she)(she)備(bei)需(xu)要(yao)針對(dui)不同的(de)水(shui)質，不同的(de)需(xu)求進(jin)行(xing)(xing)預處(chu)理。其作用(yong)就是(shi)除去水(shui)中的(de)雜質，滿(man)足反(fan)(fan)滲(shen)透(tou)設(she)(she)(she)備(bei)的(de)進(jin)水(shui)要(yao)求，保證反(fan)(fan)滲(shen)透(tou)純化系(xi)統的(de)穩定運(yun)行(xing)(xing)。
反滲(shen)透水處理設備(bei)的主要優點(dian)可總(zong)結為：除鹽率(lv)高、水質好、能耗低、連(lian)續運行、性能穩定，無(wu)需化學品再生、無(wu)污染。
