若不是因溫度和壓力的因素而引起的產水量逐漸減少15%時，或水質逐漸下降超標時，則說明反滲透膜需要進行化學清洗。在運行中，由于各種原因會偶然出現一些故障問題，出現問題后應詳細查看運行記錄，分析故障原因。三、反滲透系統(tǒng)一般故障原因分析詳細內容請點擊：反滲透設備12大常見問題維修指南四、反滲透設備短期或長期停運時的保護方法：詳情請點擊：反滲透設備短期或長期停運時的保護方法五、反滲透設備日常運行應記錄的數據；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，必須嚴格控制水的PH值，給水PH值在3-11范圍內。當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)定值將導致膜的氧化分解。若把FI值超標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計標準值。此外濃水的流量應盡量避免小于設計標準值，在濃水流量過小的條件下運轉。</p><p> 反滲透設備是將原水經過活性碳過濾器、精細過濾器等預處理過濾后，再通過反滲透膜將水質的多種物質、膠體、細菌、鹽類等分離出來，從而使水質得到進一步的凈化，本文小編就來說一說關于反滲透設備的操作方法是什么？反滲透設備的操作方法如下：開機前，觀察反滲透設備預處理水箱水位是否正常，原水壓力是否正常。檢查所有閥門，以確定閥門處于正確狀態(tài)，將反滲透設備上一級進水調節(jié)閥、濃水調節(jié)閥打開處于適當開度，二級進水調節(jié)閥、濃水調節(jié)閥打開，一級產水管路無節(jié)流裝置，二級產水排放或接入純水箱。預處理過濾器正反沖洗30分鐘，觀察預處理供水水質符合反滲透設備進水要求后，將自動控制閥旋至運行位置，進水電磁閥自動開啟，一級沖洗電磁閥開啟對一級RO膜低壓沖洗。打開保安過濾器前進水閥，將預處理之后的水導入反滲透設備，打開保安過濾器排氣閥，排盡保安過濾器內空氣，打開高壓泵排氣閥，排盡高壓泵內空氣，將預處理水導入膜內，排盡反滲透膜內空氣。繼續(xù)通入預處理水、浸泡反滲透膜，并低壓沖洗反滲透膜內保護液。以上就是反滲透設備的操作方法介紹。南昌名常貴環(huán)保設備有限公司優(yōu)質灌溉，締造將來。</p><div

預熱清洗液時應以低流量。然后以盡可能低的清洗液壓力置換元件內的原水，其壓力僅需達到足以補充進水至濃水的壓力損失即可，即壓力必須低到不會產生明顯的滲透產水。低壓置換操作能夠限度的減低污垢再次沉淀到膜表面，視情況而定，排放部分濃水以防止清洗液稀釋。循環(huán)當原水被置換掉后，濃水管路中就應該出現清洗液，讓清洗液循環(huán)回清洗水箱并保證清洗液溫度恒定。浸泡停止清洗泵的運行，讓膜元件完全浸泡在清洗液中。有時元件浸泡1小時就足夠了，但對于頑固的污染物，需要延長浸泡時間，如浸泡10～15小時或浸泡過夜。為了維持浸泡過程的溫度，可采用很低的循環(huán)流量（約為表１所示流量的10%）。高流量水泵循環(huán)按表１所列的流量循環(huán)30～60分鐘。高流量能沖洗掉被清洗液洗下來的污染物。如果污染嚴重，請采用高于表１所規(guī)定的50%的流量將有助于清洗，在高流量條件下，將會出現過高壓降的問題，單元件允許的壓降為１bar(15psi)，對多元件壓力容器允許壓降為(50psi)，以先超出為限。沖洗用清潔水（去除硬度、不含金屬離子如鐵和氯的RO產品水或去離子水）進行低壓沖洗，沖洗系統(tǒng)內的清洗液可以用預處理的合格產水，除非存在腐蝕問題。為了防止沉淀，沖洗溫度為20oC。南昌名常貴環(huán)保設備有限公司優(yōu)質產品，是走向世界的橋梁。哈爾濱醫(yī)療反滲透設備什么價格</p><p
