反滲透設(shè)備管路材質(zhì)選擇，要考慮內(nèi)部和外部的問題，內(nèi)部就是水質(zhì)對管路的腐蝕，外部就是運行環(huán)境。反滲透設(shè)備運行環(huán)境決定管路外部腐蝕情況，如果運行環(huán)境較好，一般采用表面涂層（如上油漆或者鍍鋅等）即可。水質(zhì)對管路的腐蝕要考慮余氯、化學(xué)品、PH值、溫度等。我們一般常用的有UPVC、不銹鋼等。 </p> <p> <br /> </p> <p> 不銹鋼的基本優(yōu)點是對一般腐蝕都有很好的耐性，不銹鋼很少產(chǎn)生電流腐蝕和應(yīng)力腐蝕破壞，但不銹鋼卻容易發(fā)生點蝕和縫隙腐蝕，點蝕反映金屬受到局部侵蝕，在其表面上造成凹陷孔洞，如果氧化鉻鈍化層被破壞，氯離子就會攻擊裸露的金屬形成點蝕?？p隙腐蝕與小孔、墊片表面、沉積物周圍以及螺絲下的裂縫等處的一小撮靜止水所導(dǎo)致的點蝕有關(guān)。為避免發(fā)生膜系統(tǒng)高壓管路的點蝕及縫隙腐蝕，建議如下： </p> <p> 一般水源，可以選用304不銹鋼； </p> <p> 原水含鹽量在2-5000PPM時，建議選用含碳量小于0.08%的316不銹鋼； </p> <p> 原水含鹽量在5-7000PPM時，建議選用含碳量小于0.03%的316L不銹鋼； </p> <p> 原水含鹽量在7-30000PPM時，建議選用含鉬量為4%-5%的904L不銹鋼。 </p> <p> <br />

style="text-indent:25px">反滲透設(shè)備的穩(wěn)定運行及使用壽命與日常的運行管理戚戚相關(guān)，反滲透設(shè)備運行注意事項主要集中在反滲透膜組件、反滲透高壓泵、保安過濾器、反滲透壓差、夏季高溫運行五方面。其中膜組件是保證出水水質(zhì)的關(guān)鍵部件，日常保養(yǎng)較為復(fù)雜，反滲透設(shè)備運行注意事項如下所述： 1)、反滲透膜的水解易造成反滲透裝置的性能惡化，為此，必須嚴格控制水的PH值，給水PH值在3-11范圍內(nèi)；若把FI值超標(biāo)的水供給反滲透裝置作為給水，在膜組件的表面將附著污垢，這樣必須通過清洗來去除污垢。 2)、當(dāng)注入的次氯酸鈉量不足而使給水中的游離氯不能測出時，在反滲透裝置的膜組件上會有黏泥發(fā)生，反滲透裝置的壓差將增大；但對于聚酰胺膜來講，必須嚴格控制進入膜組件的游離氯量，超過規(guī)定值將導(dǎo)致膜的氧化分解。 3)、過量的給水流量將使膜組件提前劣化，因此給水流量不能超過設(shè)計標(biāo)準(zhǔn)值。此外濃水的流量應(yīng)盡量避免小于設(shè)計標(biāo)準(zhǔn)值，在濃水流量過小的條件下運轉(zhuǎn)，會使反滲透裝置的壓力容器內(nèi)發(fā)生不均勻的流動及由于過分濃縮而在膜組件上析出污垢。 </p><p> 反滲透系統(tǒng)由反滲透膜(RO)、高壓泵及為保護反滲透膜而設(shè)置的保安過濾器組成。保安過濾器內(nèi)裝有過濾孔徑為5μm的濾芯。這些濾芯會過濾掉任何尺寸大于5μm的顆粒。對下游RO膜起到保護作用，否則RO膜表面極易結(jié)垢。目前較常用的滲透膜類別為聚酰胺膜，膜型式為卷式復(fù)合膜，該種型式的膜的除鹽率可達99.5%。由于RO膜易受水中PH值、余氯及水溫的影響，故RO膜運行前對進水水質(zhì)有嚴格要求： </p> <p> PH 值：3~10 </p> <p> 余氯值：<0.1mg/L </p> <p> SDI15值：<5.0 </p> <p> 水溫：<45 ℃ </p> <p> 以上任一指標(biāo)超出范圍，均有可能使?jié)B透膜產(chǎn)生變形，從而影響出水水質(zhì)和縮短膜的使用壽命。并且膜的種類不同對進水水質(zhì)要求也有所不同。在調(diào)試前可以根據(jù)RO膜廠家提供的說明進行確認。 </p> <p> <br /> 我們?nèi)粘Ｋ嬘玫募儍羲际墙?jīng)過反滲透設(shè)備處理的，水質(zhì)清澈。</p><div
