詳細(xì)介紹
陶氏反滲透膜RO-3840/30-FF工藝是現(xiàn)如今的膜分離應(yīng)用技術(shù),該種工藝主要是應(yīng)用膜分離性能,進(jìn)而去除水中的多余微小顆粒物質(zhì),或是以吸附能力去發(fā)揮凈化分離作用,從而使物質(zhì)進(jìn)行分級(jí)、濃縮及凈化等過程。

陶氏反滲透膜RO-3840/30-FF基本原理
當(dāng)純水和鹽水被理想半透膜隔開,理想半透膜只允許水通過而阻止鹽通過,此時(shí)膜純水側(cè)的水會(huì)自發(fā)地通過半透膜流入鹽水一側(cè),這種現(xiàn)象稱為滲透,若在膜的鹽水側(cè)施加壓力,那么水的自發(fā)流動(dòng)將受到抑制而減慢,當(dāng)施加的壓力達(dá)到某一數(shù)值時(shí),水通過膜的凈流量等于零,這個(gè)壓力稱為滲透壓力,當(dāng)施加在膜鹽水側(cè)的壓力大于滲透壓力時(shí),水的流向就會(huì)逆轉(zhuǎn),此時(shí),鹽水中的水將流入純水側(cè),上述現(xiàn)象就是水的反滲透(RO)處理的基本原理。
陶氏反滲透膜RO-3840/30-FF使用注意事項(xiàng)
1、在安裝前,保持密封包裝,干燥陰涼處保存,避免曝曬并防凍。
2、安裝時(shí),選用適當(dāng)潤(rùn)滑劑,以甘油為佳。
3、新系統(tǒng)運(yùn)行時(shí),要沖洗,將保護(hù)液及溶劑沖干凈。
4、運(yùn)行1小時(shí)后,記錄各運(yùn)行參數(shù),48小時(shí)后再記錄各運(yùn)行參數(shù),對(duì)比兩者之間的變化。
DOW™ RO elements contain high-rejection FT30 reverse osmosis membrane that has successfully been used to process a wide range of food and dairy streams. These elements are especially effective in dewatering or product concentration. All materials of construction are compliant with U.S. Food & Drug Administration indirect food contact requirements and are suitable for use in food processing applications.
Used In:
Concentration of dairy products
Dewatering of liquid foods
Advantages:
High solute rejection gives greater yields
Food grade design and construction
