class="visible-xs" style="margin:20px;text-align:center;font-size: 20px;line-height: 150%">反滲透設備的清洗方法</h1> <p style="margin:0 0 20px 0;color:#CCC;text-align:center;"> 來(lái)源：點(diǎn)擊：2193  </p> <span style="font-size: 14px;"> 在節約用水保護環(huán)境的號召下，近年來(lái)，反滲透技術(shù)因越來(lái)越具有優(yōu)越性而得到日益廣泛的應用。反滲透設備在反滲透技術(shù)的支持下，漸漸成為水處理行業(yè)通用的設備，使用十分廣泛。但是反滲透設備反滲透水處理設備的清洗問(wèn)題確實(shí)一個(gè)技術(shù)活，技術(shù)性不強的用戶(hù)在清洗反滲透設備的清洗過(guò)程中很容易就會(huì )損壞到反滲透設備，所以我公司有義務(wù)告訴大家反滲透設備正確合理的清洗方法，這樣就在很大程度上能夠避免出現嚴重的問(wèn)題。</span><br><span style="font-size: 14px;"> </span><br><span style="font-size: 14px;"> 第一種方法：低壓沖洗反滲透設備</span><br><span style="font-size: 14px;"> </span><br><span style="font-size: 14px;"> 定期對反滲透設備進(jìn)行大流量、低壓力、低pH值的沖洗有利于剝除附著(zhù)在膜表面上的污垢，維持膜性能，或當反滲透設備進(jìn)水SDI突然升高超過(guò)5.5以上時(shí)，應進(jìn)行低壓沖洗，待SDI值調至合格后再開(kāi)機。</span><br><span style="font-size: 14px;"> </span><br><span style="font-size: 14px;"> 第二種方法：反滲透設備停運保護</span><br><span style="font-size: 14px;"> </span><br><span style="font-size: 14px;"> 由于生產(chǎn)的波動(dòng)，反滲透設備不可避免地要經(jīng)常停運，短期或長(cháng)期停用時(shí)必須采取保護措施，不適當地處理會(huì )導致膜性能下降且不可恢復。短期保存適用于停運15d以下的系統，可采用每1～3d低壓沖洗的方法來(lái)保護反滲透設備。實(shí)踐發(fā)現，水溫20℃以上時(shí)，反滲透設備中的水存放3d就會(huì )發(fā)臭變質(zhì)，有大量細菌繁殖。因此，建議水溫高于20℃時(shí)，每2d或1d低壓沖洗一次，水溫低于20℃時(shí)，可以每3d低壓沖洗一次，每次沖洗完后需關(guān)閉凈水設備反滲透裝置上所有進(jìn)出口閥門(mén)。長(cháng)期停用保護適用于停運15d以上的系統，這時(shí)必須用保護液（殺菌劑）充入凈水設備反滲透裝置進(jìn)行保護。常用殺菌劑配方（復合膜）為甲醛10（質(zhì)量分數）、異噻唑啉酮20mg/L、亞硫酸氫鈉1（質(zhì)量分數）。</span><br><span style="font-size: 14px;"> </span><br><span style="font-size: 14px;"> 第三種方法：反滲透膜化學(xué)清洗</span><br><span style="font-size: 14px;"> </span><br><span style="font-size: 14px;"> 在正常運行條件下，反滲透膜也可能被無(wú)機物垢、膠體、微生物、金屬氧化物等污染，這些物質(zhì)沉積在膜表面上會(huì )引起凈水設備反滲透裝置出力下降或脫鹽率下降、壓差升高，甚至對膜造成不可恢復的損傷，因此，為了恢復良好的透水和除鹽性能，需要對膜進(jìn)行化學(xué)清洗。一般3～12個(gè)月清洗一次，如果每個(gè)月不得不清洗一次，這說(shuō)明應該改善的預處理系統，調整的運行參數。如果1～3個(gè)月需要清洗一次，則需要提高設備的運行水平，是否需要改進(jìn)預處理系統較難判斷。</span><br><span style="font-size: 14px;"> </span><br><span style="font-size: 14px;"> 綜合以上三種對不同情況下不同的處理方法，用戶(hù)們就可以大限度地延長(cháng)反滲透設備的壽命并可以提高反滲透設備的工作效率和工作質(zhì)量，掌握這三種反滲透設備的清洗方法，將是用戶(hù)們的非常大的收益。以上信息由<strong><a
