反滲透(RO)系統:了解反滲透(RO)系統中通道和階段之間的區別

1級和2級RO系統之間的區別

在一級反滲透系統中,給水作為一股水流進入反滲透系統,然后作為濃縮水或滲透水離開反滲透系統。 

在兩階段系統中,第一階段的濃縮物(或廢品)然后成為第二階段的給水。從第一階段收集的滲透水與第二階段收集的滲透水合并。附加階段可提高系統的恢復能力。

 

大批

反滲透系統中,陣列描述了兩級??系統中壓力容器的物理布置。壓力容器包含反滲透膜(通常在壓力容器中有1至6個反滲透膜)。每個階段可以有一定數量的帶有反滲透膜的壓力容器。然后,每個階段的廢品將成為下一個連續階段的進料流。前一頁顯示的2級反滲透系統是2:1陣列,這意味著前2個反滲透容器的濃縮物(或廢品)將被送入下一個反滲透容器。

具有濃縮液回收的反滲透系統

對于不能適當分級的反滲透系統,并且給水化學性質允許的話,可以利用精礦再循環設置,將一部分精礦流回饋給給水到第一級,以幫助提高系統恢復。

 

單程RO與雙程RO

可以將通行證視為獨立的反滲透系統。考慮到這一點,單程反滲透系統和雙程反滲透系統之間的區別在于,對于雙程反滲透,從第一遍通過的滲透物成為第二遍(或第二次反滲透)的給水,最終產生因為它基本上已經通過了兩個反滲透系統,所以滲透質量更高。

除了產生質量更高的滲透物外,雙程系統還允許通過在第一遍和第二遍之間注入苛性堿來從滲透物中除去二氧化碳氣體。RO后使用混合床離子交換樹脂床時,CO2是不可取的。通過在第一次通過后添加苛性堿,可以增加第一次通過的滲透水的pH值,并將CO2轉化為碳酸氫根(HCO3-)和碳酸鹽(CO3-2),以便在第二次通過中獲得更好的RO膜截留率。單程反滲透不能做到這一點,因為在存在陽離子(例如鈣)的情況下注入苛性堿并形成碳酸鹽(CO3-2)會導致反滲透膜結垢。
