25 mayankho wamba a reverse osmosis membrane technology vuto (Gawo 2)

7. Ndani amagulitsa zinthu zoyeretsera membrane kapena kuyeretsa?

Makampani oyeretsa madzi amatha kupereka zida zapadera zoyeretsera ma membrane ndi ntchito zoyeretsera, ndipo ogwiritsa ntchito amatha kugula zoyeretsera zotsuka pa membrane malinga ndi malingaliro amakampani a membrane kapena ogulitsa zida.

8. Kodi kuchuluka kovomerezeka kwa silika kolowera kwa nembanemba ya reverse osmosis ndi iti?

Kuchuluka kovomerezeka kwa silika kumadalira kutentha, pH, ndi scale inhibitor. Nthawi zambiri, kuchuluka kovomerezeka m'madzi okhazikika ndi 100ppm popanda kuwonjezera kwa scale inhibitor. Ma scale inhibitors ena amatha kuloleza kuchuluka kwa silika m'madzi okhazikika kukhala 240ppm. Chonde funsani wopereka scale inhibitor.

9. Kodi chromium imakhudza bwanji nembanemba ya RO?

Zitsulo zina zolemera monga chromium zimatha kuyambitsa makutidwe ndi okosijeni a klorini, zomwe zimapangitsa kuwonongeka kosasinthika kwa nembanemba. Izi ndichifukwa choti kukhazikika kwa Cr6 + m'madzi ndikoyipa kuposa kwa Cr3 +. Zikuwoneka kuti ma ion achitsulo okhala ndi ma oxidation valence apamwamba amakhala ndi mphamvu yowononga kwambiri. Choncho, kuchuluka kwa chromium kuyenera kuchepetsedwa kapena osachepera Cr6 + iyenera kuchepetsedwa kukhala Cr3 + mu gawo lachidziwitso choyambirira.

10. Ndi mtundu wanji wa preprocessing womwe umafunika pamakina a RO?

Dongosolo lachidziwitso choyambirira limapangidwa ndi kusefera kolimba (~ 80 ma microns) kuchotsa tinthu tating'onoting'ono, ndikuwonjezera ma okosijeni monga sodium hypochlorite, ndiye kusefa mwatsatanetsatane kudzera musefa ya multimedia kapena thanki yowunikira, kuwonjezera ma okosijeni monga sodium bisulfite kuti achepetse chlorine yotsalira, ndipo pomaliza kukhazikitsa fyuluta yachitetezo isanalowe polowera. Ntchito ya fyuluta yachitetezo, monga momwe dzinalo likusonyezera, ndikukhala ngati njira yomaliza yotetezera kuti tinthu tating'ono ting'onoting'ono zisawononge zowonongeka ndi zigawo za pampu yothamanga kwambiri. Magwero amadzi okhala ndi tinthu tambiri toyimitsidwa zolimba nthawi zambiri amafunikira milingo yayikulu yopangira mankhwala kuti akwaniritse zofunikira zomwe zatchulidwa; Kwa magwero amadzi okhala ndi kuuma kwakukulu, tikulimbikitsidwa kugwiritsa ntchito kufewetsa kapena kuwonjezera ma asidi ndi ma scale inhibitors. Kwa magwero amadzi okhala ndi ma microbial ndi organic, activated carbon kapena anti fouling nembanemba amafunikanso.

11.Kodi reverse osmosis kuchotsa tizilombo toyambitsa matenda monga mavairasi ndi mabakiteriya?

Reverse osmosis (RO) ndi wandiweyani kwambiri ndipo ali ndi mlingo wochotsa kwambiri wa mavairasi, bacteriophages, ndi mabakiteriya, osachepera 3 zipika kapena kuposa (kuchotsa mlingo> 99.9%). Komabe, ziyenera kuzindikirika kuti nthawi zambiri, tizilombo toyambitsa matenda timatha kuberekana kumbali yotulutsa madzi ya nembanemba, zomwe zimatengera kusonkhanitsa, kuyang'anira, ndi kukonza njira. Mwa kuyankhula kwina, kuthekera kwa dongosolo kuchotsa tizilombo toyambitsa matenda kumadalira kwambiri ngati dongosolo, kachitidwe, ndi kasamalidwe kake ndi koyenera m'malo motengera zomwe zili mu membrane.

12. Kodi kutentha kumakhudza bwanji kupanga madzi?

Kutentha kumapangitsa kuti madzi achuluke, ndipo mosiyana. Pogwira ntchito pansi pa kutentha kwakukulu, mphamvu yogwiritsira ntchito iyenera kuchepetsedwa kuti ikhale yofanana ndi kupanga madzi, ndi mosemphanitsa. Chonde onani mitu yokhudzana ndi kusintha kwa kutentha kwa TCF pakusintha kwamadzi.
