反滲透設(shè)備的膜在反滲透設(shè)備整體運(yùn)行上起著非常重要的作用，所以反滲透設(shè)備膜在安裝與拆卸的過(guò)程中有著很多的講究，安裝與拆卸不當(dāng)，很有可能造成無(wú)法挽回的損失。反滲透設(shè)備膜元件的安裝前的準(zhǔn)備 1、沖洗系統(tǒng)管路，如果系統(tǒng)是全新的，在安裝反滲透設(shè)備膜之前需充分沖洗系統(tǒng)管路，以避免碎片、溶劑、或者余氯等與膜元件接觸。 2、清潔壓力容器：在安裝膜元件之前需清潔壓力容器的內(nèi)部，防止污垢或碎片沉積在膜元件外表面。建議用棉球浸入50%的甘油溶液后，采用合適的工具在膜殼內(nèi)部來(lái)回擦洗，將膜殼內(nèi)壁清潔干凈。在清潔過(guò)程中，請(qǐng)注意不讓工具劃傷膜殼內(nèi)表面。</p><p> 反滲透設(shè)備的運(yùn)行管理 </p> <p>

</p> <p> <br /> </p> <p> 2、反滲透膜元件的檢查 </p> <p> （1）一般每隔半年（必要時(shí)可縮短時(shí)間），要對(duì)每套反滲透的一段、二段膜元件進(jìn)行檢查。 </p> <p> （2）開(kāi)壓力容器端蓋（使用**工具，并由技術(shù)熟練的技工操作）。 </p> <p> （3）檢查進(jìn)水段有無(wú)機(jī)械雜質(zhì)、金屬氧化物沉積，有無(wú)細(xì)菌微生物滋生，膜元件顏色有無(wú)變化，檢查膜有無(wú)結(jié)垢。 </p> <p> （4）如果需要還可以抽出反滲透膜元件進(jìn)行細(xì)致檢查，再抽進(jìn)水端膜元件時(shí)，一定不能直接抽，要把按水流方向它從壓力容器推出，安裝時(shí)同樣。 </p> <p>
