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)進行分級、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,此時膜純水側(cè)的水會自發(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)流動將受到抑制而減慢,當(dāng)施加的壓力達到某一數(shù)值時,水通過膜的凈流量等于零,這個壓力稱為滲透壓力,當(dāng)施加在膜鹽水側(cè)的壓力大于滲透壓力時,水的流向就會逆轉(zhuǎn),此時,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
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,選用適當(dāng)潤滑劑,以甘油為佳。
3、新系統(tǒng)運行時,要沖洗,將保護液及溶劑沖干凈。
4、運行1小時后,記錄各運行參數(shù),48小時后再記錄各運行參數(shù),對比兩者之間的變化。
