反滲透水處理技術(shù)通常用于海水、苦咸水的淡化，水的軟化處理、廢水處理以及食品、醫(yī)院工業(yè)的提純、濃縮、分離等方面。此外、反滲透技術(shù)應(yīng)用于除鹽預(yù)處理也取得了很好的效果，主要是使離子交換樹脂的負(fù)荷減輕91%以上，樹脂的再生計(jì)量也減少90%.因此，不僅節(jié)約了費(fèi)用而且也有利于環(huán)保，反滲透技術(shù)還可以用于去除水中的微粒、有機(jī)物、膠體物質(zhì)，對(duì)減輕離子交換樹脂的污染延長壽命都有良好的作用。大家一起來了解一下反滲透純水處理設(shè)備工作原理都哪些？反滲透水處理設(shè)備通常由原水預(yù)處理系統(tǒng)、反滲透純化系統(tǒng)、超純化后處理系統(tǒng)三部分組成。預(yù)處理的目的主要是使原水達(dá)到反滲透膜分離組件的進(jìn)水要求，保證反滲透純化系統(tǒng)的穩(wěn)定運(yùn)行。反滲透膜系統(tǒng)是一次性去除原水中98%以上離子、有機(jī)物及***微生物（理論上）經(jīng)濟(jì)高效的純化方法。超純化后處理系統(tǒng)通過多種集成技術(shù)進(jìn)一步去除反滲透純水中尚存的微量離子、有機(jī)物等雜質(zhì)，以滿足不同用途的終水質(zhì)指標(biāo)要求。反滲透（ReverseOsmosis，簡(jiǎn)稱RO）是以壓力差為推動(dòng)力的一種高新膜分離技術(shù)，具有一次分離度高、無相變、簡(jiǎn)單高效的特點(diǎn)。反滲透膜“孔徑”已小至納米（1nm=10-9m）。</p><p> 大家知道反滲透設(shè)備的反滲透膜的工作壓力不宜過低，也不能太高，過低過高都會(huì)對(duì)反滲透膜造成一定的影響，建議參考膜廠家的標(biāo)準(zhǔn)工作壓力，然后根據(jù)實(shí)際情況進(jìn)行微調(diào)，比如說水中的雜質(zhì)較多的話，就需要適當(dāng)?shù)脑黾右稽c(diǎn)壓力，這樣才能達(dá)到更好的效果。如果你還有疑惑，可以找迪奧反滲透設(shè)備廠家的提供技術(shù)協(xié)助。其實(shí)反滲透設(shè)備除了反滲透膜的工作壓力之外還需要注意以下主要參數(shù)。反滲透設(shè)備的主要參數(shù)反滲透設(shè)備對(duì)水溫的要求，反滲透膜元件對(duì)水質(zhì)都是有一定的要求的，高溫膜元件外生產(chǎn)的復(fù)合膜要求進(jìn)水水溫控制在0~45℃，醋酸纖維素膜要求進(jìn)水水溫控制在0~40℃。對(duì)進(jìn)水壓力的要求，苦咸水處理時(shí)用的工業(yè)膜高進(jìn)水壓力為600psi()，海水淡化膜高進(jìn)水壓力為1200psi()。膜的高進(jìn)水流量，8支膜元件的高進(jìn)水流量為75gpm(17t/h)。4支膜元件的高進(jìn)水流量為16gpm()。單支膜元件的損壞壓力，榮國單只膜元件的壓力太高時(shí)，就會(huì)對(duì)膜元件造成損壞。所以單支膜的高壓力不能超過Mpa(10psi)。濃縮水和透過水量之比，每支膜的抗污染力都是有限的，所以膜的濃縮水與透過水量之比是有一定要求的，所以要求單支膜元件濃縮水與透過水量的小比例為5：1。南昌名常貴環(huán)保設(shè)備有限公司以真誠為先導(dǎo)，以務(wù)實(shí)為基礎(chǔ)。</p><div
