當(dāng)把相同體積的稀溶液和濃液分別置于一容器的兩側(cè)，中間用半透膜阻隔，稀溶液中的溶劑將自然的穿過半透膜，向濃溶液側(cè)流動(dòng)，濃溶液側(cè)的液面會(huì)比稀溶液的液面高出一定高度，形成一個(gè)壓力差，達(dá)到滲透平衡狀態(tài)，此種壓力差即為滲透壓。若在濃溶液側(cè)施加一個(gè)大于滲透壓的壓力時(shí)，濃溶液中的溶劑會(huì)向稀溶液流動(dòng)，此種溶劑的流動(dòng)方向與原來滲透的方向相反，這一過程稱為反滲透。起源早使用于美國(guó)太空人將尿液回收為純水使用。醫(yī)學(xué)界還以反滲透法的技術(shù)用來洗腎（血液透析）。反滲透膜可以將重金屬、農(nóng)藥、細(xì)菌、、雜質(zhì)等徹底分離。整個(gè)工作原理均采用物理法，不添加任何殺菌劑和化學(xué)物質(zhì)，所以不會(huì)發(fā)生化學(xué)變相。并且反滲透膜并不分離溶解氧，所以通過此法生產(chǎn)得出的純水是活水，喝起來清甜可口。反滲透，英文為ReverseOsmosis，它所描繪的是一個(gè)自然界中水分自然滲透過程的反向過程。早在1950年美國(guó)科學(xué)家，隔了幾秒后吐出一小口的海水。他由此而產(chǎn)生疑問：陸地上由肺呼吸的動(dòng)物是無法飲用高鹽份的海水，那為什么海鷗就可以飲用海水呢？這位科學(xué)家把海鷗帶回了實(shí)驗(yàn)室，經(jīng)過解剖發(fā)現(xiàn)在海鷗嗉囊位置有一層薄膜，該薄膜構(gòu)造非常精密。海鷗正是利用了這薄膜把海水過濾為可飲用的淡水。南昌名常貴環(huán)保設(shè)備有限公司優(yōu)質(zhì)產(chǎn)品，是走向世界的橋梁。貴陽純水反滲透設(shè)備報(bào)價(jià)咨詢</p><p

進(jìn)水壓力對(duì)反滲透膜的影響反滲透膜的進(jìn)水壓力不會(huì)對(duì)鹽的透過量造成直接的影響，但是進(jìn)水壓力升高會(huì)讓反滲透的靜壓力升高，因?yàn)楫a(chǎn)水量加大了，這時(shí)候的鹽透過量變化不會(huì)太大，產(chǎn)水量增加了就稀釋了透過膜的鹽分，降低了透鹽率，這不就相當(dāng)于升高了脫鹽率嗎。當(dāng)進(jìn)水壓力超過一定值時(shí)，由于過高的回收率，加大了濃差極化，又會(huì)導(dǎo)致鹽透過量增加，抵消了增加的產(chǎn)水量，使得脫鹽率不再增加。反滲透設(shè)備壓力開關(guān)怎樣調(diào)試？水處理反滲透設(shè)備高/低壓保護(hù)，是為了防止RO高壓泵空轉(zhuǎn)或在超過極限高/低壓下工作。高壓開關(guān)，是高壓保護(hù)用的。隨著設(shè)備使用時(shí)間增長(zhǎng)，膜會(huì)污堵，自然膜進(jìn)口壓力會(huì)增高，當(dāng)壓力增高到一定程度，為了保護(hù)設(shè)備、管道不破損，就需要有高壓開關(guān)進(jìn)行保護(hù)，壓力增加到壓力開關(guān)預(yù)設(shè)值時(shí)，會(huì)強(qiáng)制設(shè)備停機(jī)。低壓開關(guān)，當(dāng)進(jìn)水管內(nèi)壓力低時(shí)，反滲透膜不能正常工作，會(huì)一直排廢水，所以當(dāng)進(jìn)水壓力達(dá)不到工作要求時(shí)，就會(huì)切斷電路，讓機(jī)器停止工作。當(dāng)進(jìn)水管內(nèi)壓力達(dá)到工作要求時(shí)，又會(huì)開始工作。低壓開關(guān)有兩個(gè)可調(diào)螺絲，一個(gè)是調(diào)基準(zhǔn)壓力，一般為0-6bar，一個(gè)是調(diào)回差壓力，一般為0-2bar，可以對(duì)照著用螺絲刀調(diào)節(jié)。常見低壓開關(guān)總是跳有兩種可能性。貴陽純水反滲透設(shè)備報(bào)價(jià)咨詢</p><p
