2.外觀的區別：單級反滲透設備與雙極反滲透設備的外觀區別在于，單級設備配置一臺立式泵，雙極反滲透設備配置兩臺立式泵。
3.運行系統不同：系統的不同之處在于，單級設備是通過膜分離技術除去水中一些物質的設備。雙極反滲透設備是指通過兩個反滲透膜對原水進行過濾，從而達到較高的脫鹽率標準。當原水水質接近自來水時，采用二級反滲透技術，水的電導率可達10μs/cm。一般工業或其他行業對水質要求不太高時，采用單級設備。如果對水質有嚴格要求，則采用雙級反滲透設備。
4.工藝流程不同： 單級反滲透設備又稱一級反滲透設備，即原水經預處理系統和精密過濾器經高壓泵送至反滲透裝置，直接產生產品水，稱為單級反滲透。兩級反滲透設備又稱兩級反滲透。原水加壓進入預處理系統粗濾，進入精密過濾器過濾。之后由一級高壓泵加壓至一級反滲透系統。系統產生的水由二級高壓泵加壓至二級反滲透系統，產生產品水，稱為二級反滲透。
