1.給水壓力低的原因可能是：（1）給水流速不適當；（2）系統(tǒng)泄漏；（3）高壓泵入口水壓力不足或泵部漏水、漏氣；（4）精密過濾器濾芯污堵；（5）高壓泵故障。 2.給水壓力高的原因可能是：（1）高壓泵出口門調(diào)節(jié)不當；（2）從高壓泵到反滲透器之間的管道堵塞；（3）濃水調(diào)節(jié)門關的太緊或堵塞，濃水排放流量??；（4）回收率太低。 3.回收率低的原因可能是：（1）給水流速過高；（2）給水壓力或濃度低。 4.回收率高的原因可能是：（1）給水壓力過高；（2）給水流速不足； 5.反滲透設備兩端壓降高的原因可能是：（1）濃水流速高；（2）膜元件污染； 6.高壓泵停止運轉的原因可能是：（1）泵出水壓力過高（大于1.7MPa）；（2）泵入口水壓力過低（小于0.05MPa）。 7.反滲透設備產(chǎn)水量降低的原因可能是：（1）給水溫度低；（2）給水壓力低；（3）濃水濃度太高引起高的滲透壓；</p><p style="text-indent:25px">反滲透設備預處理藥劑與處理中使用的藥劑，包括混凝劑、助凝劑、氧化劑、還原劑、阻垢劑等，尤其是混凝劑和阻垢劑，這些藥劑的選擇、加藥量甚至藥品配方法都會對反滲透的運行有很大的影響。通常，我們會注意檢測進水的鐵含量，其實進水中的鋁含量高也會造成反滲透膜的污染。鋁對膜的污染是由于氫氧化鋁沉淀而導致的，氫氧化鋁沉淀物通常以膠體形式存在，是一種兩性氫氧化物，在6.5-6.7的pH范圍內(nèi)具有很小的溶解度，如果鋁凝聚過程在太高或太低的pH值下進行，鋁離子將進入反滲透裝置中造成反滲透膜的污染，因此對于采用鋁鹽為凝聚劑的預處理系統(tǒng)，其pH值較好控制在6.5-6.7，使鋁的溶解度達到較小，注意根據(jù)水質(zhì)及時調(diào)整加藥量，可能的話要定期檢測經(jīng)預處理過的水中的鋁含量，并控制在0.05mg/L以下。反滲透純凈水設備都是采用了這種技術，采用了自動供水和斷水的智能化控制，這就是純凈水設備。</p><div
