Mun samar da ingantattun mafita a bangaren ruwa

Yadda za a magance rarrabawar hankali na membrane osmosis baya

Tsarin juzu'i na osmosis wani bangare ne mai mahimmanci na kananan kayan aiki na tsaftataccen ruwa mai tsafta, amma kuma akwai wani hadari mai boye a cikin tsarin bayajin osmosis, ma'ana, farfajiyar membrane ta baya mai sauki ne don samar da karko mai karfi ta hanyar warwarewa ko wasu abubuwa masu riƙewa, wanda zai shafi ingancin ƙazantar kayan aikin maganin ruwa.

1. methodara saurin gudu

Da farko dai, zamu iya ɗaukar matakan da aka saba amfani dasu a masana'antar sunadarai don haɓaka rikice-rikice. Wato, yi ƙoƙarin ƙara saurin layin ruwan da ke gudana ta saman membrane. Za'a iya rage lokacin tallatawa na ragewa ta hanyar rage lokacin zama na ruwa da kuma kara saurin gudu na ruwa a cikin kananan da matsakaiciyar sikandiyyar tsaftataccen ruwan magani.

2. Hanyar shiryawa

Misali, ana saka duniyoyin 29 ~ 100um a cikin ruwa mai magani kuma suna gudana ta cikin tsarin osmosis tare don rage kaurin layin iyakar membrane da kara saurin yaduwar. Za'a iya yin kayan ƙwallan da gilashi ko methyl methacrylate. Bugu da kari, don tsarin osmosis na tubular baya, ana iya cika ball soso na ball a cikin ruwan abincin. Koyaya, don farantin da nau'ikan membrane membrane, hanyar ƙara filler bai dace ba, galibi saboda haɗarin toshe hanyar tashar.

3. Hanyar bugun jini

Addedara injin janareta a cikin aikin kayan aikin gyaran ruwa. Limar da ƙarfin bugun jini sun bambanta. Gabaɗaya, mafi girman amplitude ko mita, mafi girman saurin gudu ne. Ana amfani da agitators a cikin duk na'urorin gwaji. Kwarewa ya nuna cewa coefficient na canja wurin taro yana da alaƙa ta linzami tare da yawan juyin juya halin mai tayar da hankali.

4. Shigar da mai talla da tashin hankali

Masu tallata tashin hankali iri-iri iri-iri ne waɗanda ke iya haɓaka tsarin gudana. Misali, don abubuwan tubular, an saka baffles karkace a ciki. Ga farantin karfe ko mirgine nau'in membrane module, raga da sauran kayan za a iya yin layi don inganta tashin hankali. Tasirin mai talla da tashin hankali yana da kyau ƙwarai.

5. Add dispersive sikelin mai hanawa

Don hana membrane na osmosis baya daga sikeli a cikin kayan maganin ruwa, an ƙara acid mai ƙanshi ko hydrochloric acid don daidaita darajar pH. Koyaya, saboda lalatawa da zubewar tsarin acid, mai gudanarwar yana cikin damuwa, don haka ana ƙara maɓallin sikelin rarrabawa don kiyaye aikin yau da kullun na tsarin kula da ruwa.
