反滲透膜表面在運行中由于給水帶入的物質(zhì)的污染面產(chǎn)生污垢，例如金屬氧化物的水合物、鈣的沉淀物，有機物和微生物。這些物質(zhì)在適當?shù)牟僮鳁l件下可借助于化學藥劑的清洗和有效地除去，稱為反滲透膜的清洗。反滲透系統(tǒng)污垢產(chǎn)生的因素預(yù)處理方式不當；預(yù)處理運行不正常；給水系統(tǒng)(管道、泵、閥門等)材料選擇不當；加化學藥品的系統(tǒng)(計量泵等)不正常；停機后沖洗不當；操作控制(如回收率、產(chǎn)品水水通量、給水流速等)不當；長期運行中積累的鈣、硅等沉淀物；反滲透給水的水源改變；給水水源的生物污染。反滲透系統(tǒng)污垢的判別反滲透復合膜的清洗，由于其對PH值和溫度的高穩(wěn)定性，只要選擇清洗工藝得當，就可以達到較好的清洗效果。如果未及時清洗，拖延太久，就很難徹底清洗千凈。有效的清洗是依據(jù)污垢的性質(zhì)選擇清洗化學藥品。錯誤選擇藥品將使污垢惡化，因而清洗前可根據(jù)下述幾個方面弄清污垢種類:反滲透裝置和系統(tǒng)的配置和組合;給水水化學分析成分;以前清洗的檢查結(jié)果;SDI測定的過濾膜上的污物分析;5μm過濾器濾芯上沉積物的分析;檢查給水管道內(nèi)表面打開壓力容器端部觀察在膜元件的進水端污垢的外狀(如紅棕色則可能是鐵污垢，生物污垢或有機物通常為黏性膠狀物)。南昌名常貴環(huán)保設(shè)備有限公司強化競爭意識，營造團隊精神。</p><div
