直飲水設備能夠穩定運行是基于一定的條件之上，只有滿足這些條件才能夠使直飲水設備達到一個*的工作狀態，滿足對高品質水源的需求，所以以下這些直飲水設備運行條件用戶應準確掌握。<div> </div><div>直飲水設備工藝通常由反滲透膜、高壓泵、還有精密過濾器等裝置組成。保安過濾器里有過濾孔徑大約為5μm的濾芯。這種濾芯能夠過濾掉大于5μm的大型顆粒物質，從而保護下游反滲透膜，該情況下的防滲透膜除鹽率zui高能達99.5%。由于原水PH值得影響，膜運行前要對原水水質要個要求，原水PH值要控制在3-10，余氯值應該小于0.1mg/L，SDI15值小于5.0，水溫溫度控制在45℃以下。任何一項指標超標，都會造成RO膜的損壞。</div><div> </div><div>水溫對產水量的影響也是非常明顯的，隨著水溫的增加，水通量幾乎呈線性增大的趨勢，這主要歸功與透過膜的水分子粘度下降，擴散能力增加；系統由于存在著進水水溫可能產生變化，當溫差比較大的時候，就比較難于判斷膜系統是否被污染或是否性能下降，因此，就必須對RO進行數據標準化。</div><div> </div><div>通過初始運行72小時的數據為原始數據得出校正流量，并把該流量作為參考標準值，當系統工況出現變化時，利用標準化后的數據進行比較，在流量下降15%時應考慮對系統進行維護性清洗，以防止膜出現嚴重的污堵現象。</div><div> </div><div>RO膜作為直飲水設備核心過濾元件，它的性能決定整個系統的性能，所以用戶一定要掌握準確的運行條件，以保證產水質量。</div><p

/></p><div>直飲水設備是現如今公共場所非常普及的一款飲用水供應設備，因此產水一旦哪個指標不合格，就會嚴重威脅飲用者的健康，為了避免這一問題，我們應詳細了解造成指標不達標的原因有哪些，根據實際情況及時解決問題：</div><div> </div><div>TOC反應的是水受到有機物污染的程度，一旦TOC指標增大那么肯定是受到了有機物污染，直飲水是由直飲水設備制得的，那么TOC指標增大一定是設備受到了污染，基本總結為以下幾種情況：</div><div> </div><div>1、如果設備運行良好且直飲水不合格的話，就說明反滲透膜組件的脫鹽能力下降，需要更換了。</div><div> </div><div>2、設備運行中突然純水不合格，是因為膜組件的密封圈和連接器出現的問題，建議分段檢查找出異常端，跟換新的配件，設備剛開機二級電導率變化很大且很難調節下來，這種說明的問題就是一級后二級前的二氧化碳脫除裝置出現問題。</div><div> </div><div>3、其他問題：</div><div> </div><div>有的時候還會出現電導率合格直飲水中的亞硝酸鹽超標或者細菌超標的問題，這種問題一般來源于管道，現在大部分廠家在提供設備的時候，缺乏必要的直飲水管道處理，有的廠家可能從來沒處理過，造成設備間斷運行后菌斑形成，這種問題出現后只能大面積的更換純水管道，一般的清潔和消毒都不是十分好用。</div> </div> <div class="articleCtrl"> <p
