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(huì)對(duì)反滲透的運(yùn)行有很大的影響。 </p> <p> 通常，我們會(huì)注意檢測(cè)進(jìn)水的鐵含量，其實(shí)進(jìn)水中的鋁含量高也會(huì)造成反滲透膜的污染。鋁對(duì)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(guò)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(duì)于采用鋁鹽為凝聚劑的預(yù)處理系統(tǒng)，其pH值比較好控制在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(shí)調(diào)整加藥量，可能的話要定期檢測(cè)經(jīng)預(yù)處理過(guò)的水中的鋁含量，并控制在0.05mg/L以下。 </p><p style="text-indent:25px">預(yù)處理系統(tǒng)介紹反滲透水處理系統(tǒng)一般包括預(yù)處理系統(tǒng)、反滲透裝置、后處理系統(tǒng)、清洗系統(tǒng)和電氣控制系統(tǒng)。預(yù)處理系統(tǒng)一般包括石英砂過(guò)濾器、活性炭過(guò)濾器、精密過(guò)濾器等。其主要作用是降低原水的污染指數(shù)和余氯等其他雜質(zhì)，達(dá)到反滲透的進(jìn)水要求。預(yù)處理系統(tǒng)詳細(xì)分類說(shuō)明：1、石英砂過(guò)濾器石英砂過(guò)濾器主要去除水中的懸浮物、膠體、泥沙、粘土、腐植物、顆粒物等雜質(zhì)?？山档退臐岫?，達(dá)到水質(zhì)澄清的目的，保護(hù)反滲透膜。2、活性炭過(guò)濾器活性炭過(guò)濾器主要利用活性炭表面大量的羥基（氫氧基）和羥基等官能團(tuán)，對(duì)各種物質(zhì)進(jìn)行化學(xué)吸附，去除水中的異味、有機(jī)物、膠體、鐵及余氯，同時(shí)降低水的色度、濁度，減少對(duì)反滲透系統(tǒng)的污染。3、軟化器利用離子交換樹脂上的鈉離子交換水中的鈣鎂離子，降低水的硬度，同時(shí)用軟水鹽進(jìn)行離子交換樹脂再生。軟水鹽又名離子交換樹脂再生劑。反滲透水設(shè)備具有水質(zhì)好、耗能低、無(wú)污染、工藝簡(jiǎn)單、操作簡(jiǎn)便等優(yōu)點(diǎn)。</p><div

1、通常膜元件置于1%濃度的亞硫酸氫鈉溶液中保存，首先應(yīng)用純水充分沖洗。 </p> <p> 2、膜元件的給水側(cè)有一個(gè)濃水密封圈、注意密封圈的安裝方向是口朝上張開。濃水密封圈的功能是保證原水全部流到膜元件內(nèi)不發(fā)生龐流。原水自身流速會(huì)使?jié)馑芊馊Φ拈_口朝壓力容器內(nèi)壁緊壓密封。若密封圈的安裝方向相反，原水不能密閉，造成一部分原水流到膜元件外側(cè)，使膜表面流速降低，導(dǎo)致產(chǎn)生結(jié)垢，從而縮短膜的使用壽命。 </p> <p> 3、確認(rèn)O型圈安裝在連接配件指定位置上，安裝時(shí)要注意O型圈及連接件表面沒有劃傷或附著物。注意不要將O型圈扭曲安裝。若連接件發(fā)生泄漏，原水就會(huì)進(jìn)入到產(chǎn)水中，會(huì)導(dǎo)致產(chǎn)水水質(zhì)下降。安裝在集水管上時(shí)，O型圈和集水管的表面用純水、蒸餾水或甘油沾濕以便于安裝。 </p> <p> <br /> 反滲透是指如果在高濃度的一邊加壓，使水份從高濃度迫往低濃度的一邊，把水凈化。東莞反滲透設(shè)備要多少錢</p><p style="text-indent:25px">反滲透設(shè)備采用進(jìn)口反滲透膜，脫鹽率高，使用壽命長(zhǎng)，運(yùn)行成本低廉。徐匯區(qū)反滲透設(shè)備哪家專業(yè)</p><p
