style="text-indent:25px">反滲透設(shè)備預(yù)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(yùn)行有很大的影響。通常，我們會注意檢測進(jìn)水的鐵含量，其實(shí)進(jìn)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(dǎo)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(jìn)行，鋁離子將進(jìn)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(yù)處理系統(tǒng)，其pH值較好控制在6.5-6.7，使鋁的溶解度達(dá)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(yù)處理過的水中的鋁含量，并控制在0.05mg/L以下。嘉興反滲透設(shè)備批發(fā)廠家反滲透設(shè)備安裝在室內(nèi)的必須保證室溫不得低于0度。</p><div

1、空氣排水和再沖水組件交替用水或清洗液注滿，再用空氣把水火清洗液排出。清洗作用靠空氣/水界面的湍流結(jié)果。采用此技術(shù)時，要防止膜脫水。如用清洗液灌注，pH值大于10或小于4的配方和毒性較大的配方，不得采用此項技術(shù)。 2、反向流清洗反向清洗對受腐蝕產(chǎn)物、淤泥污染的膜組件特別有效，因為這些污染物大都沉積在給水進(jìn)水端一側(cè)。具體做法是把清洗液輸液管接到RO段的濃水口，把清洗液排放管接到RO段的進(jìn)水口。對于受淤泥污染的膜組件，采用交替正洗、反洗也是有效的。每次運(yùn)行時間大約為30s~3min。假如頻繁換向，應(yīng)當(dāng)配備岐管和閥門，以減少換向時清液的泄漏。</p><p style="text-indent:25px">運(yùn)行人員的既能水平的高低、取決于運(yùn)行人員能否及時發(fā)現(xiàn)并正確處理系統(tǒng)的缺陷和隱患是影響反滲透設(shè)備運(yùn)行的重要因素。運(yùn)行人員的誤操作對系統(tǒng)的危害更大，而且對這種膜元件的損壞常常是無法恢復(fù)的。反滲透設(shè)備重啟前和運(yùn)行后的沖洗工作一定要做好，防止設(shè)備中有殘余氣體在高壓下運(yùn)行，形成氣錘會損壞膜，以及膜濃水側(cè)的無機(jī)鹽的濃度高于原水，易結(jié)垢而污染膜。操作壓力、回收率（或濃水排放量）、進(jìn)水的SDI（污染指數(shù)）、pH、余氯和溫度是反滲透裝置的主要運(yùn)行控制參數(shù)；脫鹽率、產(chǎn)水量和壓差是三個主要監(jiān)視性能參數(shù)。在運(yùn)行管理中必須嚴(yán)格遵守，決不能隨意改變操作條件。特別是要防止提高回收率來增加產(chǎn)水量，導(dǎo)致反滲透膜面產(chǎn)生結(jié)垢；要防止在SDI值超標(biāo)的情況下繼續(xù)運(yùn)行，導(dǎo)致反滲透膜的堵塞；要防止在允許較大壓差以上繼續(xù)工作而造成膜元件的破壞性損壞。反滲透設(shè)備裝置自動化程度高，運(yùn)行維護(hù)和設(shè)備維護(hù)工作量很少。</p><div

隨著反滲透設(shè)備的使用時間加長產(chǎn)水量會隨之減少，但是到冬季產(chǎn)水量會變得更少，這是因為水溫低透水性變小，反滲透膜密度也會相應(yīng)產(chǎn)生變化，導(dǎo)致產(chǎn)水量更少。應(yīng)加強(qiáng)預(yù)處理裝置反洗次數(shù)，沖洗時間增長，精濾芯要勤換，反滲透膜反洗時間加長，壓力激增，這樣才會保證反滲透設(shè)備正常運(yùn)行。通常水溫每下降1℃，反滲透膜的產(chǎn)水量下降3%，冬天的產(chǎn)水量約為夏天產(chǎn)水量的50%左右。廢水增加，由于產(chǎn)水量降低，廢水的流量會相應(yīng)增加，廢水比增大，這是正?，F(xiàn)象，待溫度回升后，廢水會減少，產(chǎn)水流量增加。反滲透設(shè)備如果安裝在室外，必須有防凍措施，如果沒有防凍措施可能會導(dǎo)致濾瓶、膜殼等凍裂，溫度在零度以下必須停止使用水處理設(shè)備。反滲透設(shè)備安裝在室內(nèi)的必須保證室溫不得低于0度，由于水在凝固過程體積會膨脹，如果結(jié)冰，直接導(dǎo)致凈水器所有的管路、濾瓶、膜殼等都會爆裂，從而發(fā)生漏水。反滲透設(shè)備預(yù)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。嘉興反滲透設(shè)備批發(fā)廠家</p><p
