反滲透技術(shù)因具有特殊的優(yōu)越性而得到日益的應(yīng)用。反滲透凈水設(shè)備的清洗問題可能使許多技術(shù)力量不強(qiáng)的用戶遭受損失，所以要做好反滲透設(shè)備的管理，就可以避免出現(xiàn)嚴(yán)重的問題。1.低壓沖洗反滲透設(shè)備定期對反滲透設(shè)備進(jìn)行大流量、低壓力、低pH值的沖洗有利于剝除附著在膜表面上的污垢，維持膜性能，或當(dāng)反滲透設(shè)備進(jìn)水SDI突然升高超過，應(yīng)進(jìn)行低壓沖洗，待SDI值調(diào)至合格后再開機(jī)。2.反滲透設(shè)備停運保護(hù)由于生產(chǎn)的波動，反滲透設(shè)備不可避免地要經(jīng)常停運，短期或長期停用時必須采取保護(hù)措施，不適當(dāng)?shù)靥幚頃?dǎo)致膜性能下降且不可恢復(fù)。短期保存適用于停運15d以下的系統(tǒng)，可采用每1～3d低壓沖洗的方法來保護(hù)反滲透設(shè)備。實踐發(fā)現(xiàn)，水溫20℃以上時，反滲透設(shè)備中的水存放3d就會發(fā)臭變質(zhì)，有大量細(xì)菌繁殖。因此，建議水溫高于20℃時，每2d或1d低壓沖洗一次，水溫低于20℃時，可以每3d低壓沖洗一次，每次沖洗完后需關(guān)閉凈水設(shè)備反滲透裝置上所有進(jìn)出口閥門。長期停用保護(hù)適用于停運15d以上的系統(tǒng)，這時必須用保護(hù)液（殺菌劑）充入凈水設(shè)備反滲透裝置進(jìn)行保護(hù)。常用殺菌劑配方（復(fù)合膜）為甲醛10（質(zhì)量分?jǐn)?shù)）、異噻唑啉酮20mg/L、亞硫酸氫鈉1（質(zhì)量分?jǐn)?shù)）。北京商用反滲透設(shè)備南昌名常貴環(huán)保設(shè)備有限公司效益來源于服務(wù)社會的回報。</p><div

④估算所用清洗液體積;⑤保證清洗液進(jìn)入系統(tǒng)前，所有的清洗藥品完全溶解和混合;⑥清洗液的溫度和pH值范圍符合規(guī)定值。清洗方法[3]一般的化學(xué)清洗步驟如下所示。具體的事項根據(jù)現(xiàn)場的工作條件及清洗的要求確定。①沖洗膜元件。用反滲透產(chǎn)水或離子交換水進(jìn)行幾分鐘沖洗。②配置藥品。保證藥品完全溶解。③循環(huán)。用低流量置換膜元件中的水，排放一部分清洗液后，進(jìn)行循環(huán)。循環(huán)流量以表8的范圍為準(zhǔn)。污染嚴(yán)重時，如果選擇大流量循環(huán)，則有可能會產(chǎn)生壓差過高的問題，從而損壞膜元件(單支膜元件大壓降MPa)。此時，采用以下方法進(jìn)行操作比較可靠：-循環(huán)運行開始5分鐘，按設(shè)定流量1/3的量進(jìn)行循環(huán);-循環(huán)5–10分鐘間，按設(shè)定流量2/3的循環(huán)流量循環(huán);-10分鐘后按流量要求循環(huán)。循環(huán)的時間要根據(jù)具體情況決定。一般以1小時為準(zhǔn)。這期間要隨時檢測pH值是否變化。壓力應(yīng)該盡量保持較低的水平，盡可能的沒有產(chǎn)水出現(xiàn)。同時監(jiān)測壓差是否有變化。④浸泡及再循環(huán)。緩慢關(guān)閉反滲透膜元件入口的閥門，循環(huán)量接近零時，關(guān)閉循環(huán)泵。為了防止液體流出壓力容器，浸泡時可以關(guān)閉相關(guān)的閥門。浸泡的時間根據(jù)污染的程度決定。一般在1–12小時范圍。浸泡后打開相關(guān)閥門再進(jìn)行循環(huán)。⑤沖洗。</p><p> 然后調(diào)整控制器，達(dá)到運行狀態(tài)。9、將反滲透設(shè)備主機(jī)電控面板上電源開關(guān)，由OFF關(guān)位旋至ON開位，電源接通使進(jìn)水電磁閥打開，加壓水泵及高壓水泵同時啟動。10、反滲透主機(jī)電源開關(guān)打開時，微電腦控制器內(nèi)部設(shè)置將沖洗電磁閥馬上打開，反滲透主機(jī)自動沖洗。電源每關(guān)閉、啟動一次，自動沖洗都進(jìn)行一次。電源關(guān)閉時，計時取消，恢復(fù)到零位，下次啟動重新計時。11、設(shè)備運行中當(dāng)進(jìn)水水壓低于低壓開關(guān)設(shè)定值時，低壓開關(guān)動作，微電腦控制器內(nèi)部設(shè)置將主機(jī)高壓泵關(guān)閉。待水壓恢復(fù)時，主機(jī)高壓泵自動啟動。12、待反滲透純水設(shè)備主機(jī)沖洗結(jié)束后，適當(dāng)調(diào)整高壓泵泵后節(jié)流閥，控制膜前進(jìn)水壓力不得超過15kg/cm2。同時調(diào)整濃水調(diào)節(jié)閥，控制純水流量。滿足上述條件后，再將濃水調(diào)節(jié)閥與高壓泵節(jié)流閥配合使用調(diào)整，使設(shè)備回收率在合適范圍內(nèi)。無論任何時候，都不要將濃水調(diào)節(jié)閥完全關(guān)閉，否則會使反滲透主機(jī)壓力突然升高，造成設(shè)備的損壞或危及操作者的安全。南昌名常貴環(huán)保設(shè)備有限公司確保工作生產(chǎn)安全,關(guān)愛生命,以人為本。</p><div

若不是因溫度和壓力的因素而引起的產(chǎn)水量逐漸減少15%時，或水質(zhì)逐漸下降超標(biāo)時，則說明反滲透膜需要進(jìn)行化學(xué)清洗。在運行中，由于各種原因會偶然出現(xiàn)一些故障問題，出現(xiàn)問題后應(yīng)詳細(xì)查看運行記錄，分析故障原因。三、反滲透系統(tǒng)一般故障原因分析詳細(xì)內(nèi)容請點擊：反滲透設(shè)備12大常見問題維修指南四、反滲透設(shè)備短期或長期停運時的保護(hù)方法：詳情請點擊：反滲透設(shè)備短期或長期停運時的保護(hù)方法五、反滲透設(shè)備日常運行應(yīng)記錄的數(shù)據(jù)；六、運行注意事項：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(yán)格控制水的PH值，給水PH值在3-11范圍內(nèi)。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(yán)?格控制進(jìn)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。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。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)。南昌名常貴環(huán)保設(shè)備有限公司誠信為本質(zhì)量佳，質(zhì)量服務(wù)譽(yù)天下。北京商用反滲透設(shè)備</p><p
