陶氏反滲透膜RO-3838/30-FF基本原理
當(dāng)純水和鹽水被理想半透膜隔開(kāi),理想半透膜只允許水通過(guò)而阻止鹽通過(guò),此時(shí)膜純水側(cè)的水會(huì)自發(fā)地通過(guò)半透膜流入鹽水一側(cè),這種現(xiàn)象稱(chēng)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(guò)膜的凈流量等于零,這個(gè)壓力稱(chēng)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-3838/30-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。
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。
