Na li-membrane tsa osmosis li ka sebelisoa hape ka mor'a hore li nkeloe sebaka?
Ka kakaretso, li-membrane tsa reverse osmosis li ka hloekisoa.
Caustic soda le hydrochloric acid hangata li sebelisoa indastering, 'me sesebelisoa se khethehileng sa ho hloekisa ntle le marang-rang se sebelisoa ka mocheso o itseng. Mokhoa ona o kenyelletsa ho hlatsoa ka soda ea caustic pele, ebe ka caustic soda, le ho inela nako e telele. Ho rarahana ha mokhoa ona ho feta tsebo ea batho ba tloaelehileng.
Kahoo ha ho kgothaletswe ho hloekisa lera la reverse osmosis, kaha le thata haholo ebile ha le bonolo ho le hloekisa.
Mokhoa oa ho hloekisa
- Sehlapo sa enzyme se sebelisoa ho phekola lera, le sebetsang ka ho khetheha khahlano le tšilafalo ea lintho tse phelang, haholo liprotheine, oli le lintho tse ling tse silafatsang tsa tlhaho. Phello ea ho hloekisa e betere ho 50-60 ℃. Ka kakaretso, ka mor'a ho matha matsatsi a 10 kapa halofo ea khoeli, sesepa sa 1% sa enzyme se sebelisetsoa ho hloekisa lera tlas'a khatello e tlaase. Ka lebaka la tšebeliso e tlase ea sesepa sa enzyme, ho hlokahala nako e telele ea ho qoelisoa.
- Tharollo ea citric acid e sebelisoa ho tsoela pele kapa ka cyclically rinse lera ka 1% -2% citric acid aqueous tharollo tlas'a khatello e phahameng kapa tlaase, e nang le phello e ntle ea ho hloekisa ho Fe (OH) 3 tšilafalo.
- Motsoako oa letsoai o nang le letsoai o sebetsa hantle bakeng sa ho hloekisa lera ka tšilafalo e matla ea maoto le matsoho. Lebaka ke hobane tharollo ea letsoai e phahameng e ka fokolisa litšebelisano lipakeng tsa li-colloid le ho khothaletsa sebopeho sa li-colloidal aggregates.
- Tharollo ea hydrogen peroxide, ho etsa mohlala, ho hlapolla 0.5L ea 30% H2O2 ka 12L ea metsi a deionized ebe o hloekisa bokaholimo ba lera, e sebetsa ka ho khetheha khahlanong le tšilafalo ea lintho tse phelang.
- Emulsion e qhibilihang ka metsi e sebetsa haholo bakeng sa ho hloekisa li-membrane tse silafalitsoeng ka oli le tšepe ea oxide, hangata e hloekisa metsotso e 30-60.
- Mokhoa o bonolo ka ho fetisisa oa ho hloekisa 'mele ke ho sebelisa khatello e tlase le phallo e phahameng ea metsi a phallang ka potlako ka metsotso e 30, e ka khutlisetsang ho kenella ha lera ho isa tekanyong e itseng. Leha ho le joalo, ha nako e ntse e ea, permeability e ntse e fokotseha. Ntle le moo, motsoako oa metsi le moea o ka sebelisoa ho theola lera ka tlas'a khatello e tlase metsotso e 15. Mokhoa ona o sebetsa hantle bakeng sa ho hloekisa li-membrane tseo qalong li silafalitsoeng ke lintho tse phelang.
Na ho na le tekanyetso e khethehileng ea ho khutlisa li-membrane tsa reverse osmosis?
Ka kakaretso, ka mor'a nako ea tšebeliso, tlhahiso ea metsi ea lera e tla fokotseha, khatello ea tlhahiso ea metsi e tla eketseha, 'me conductivity ea lera le eona e tla ameha. Ha mathata ana a etsahala, lera la hau le ka hloekisoa kapa la nkeloa sebaka.
Haeba khatello le tlhahiso ea metsi ea lera la reverse osmosis ka mor'a ho hloekisa ho finyella litlhoko, ho lekane, empa conductivity ka kakaretso ha e fokotsehe ntle le haeba lesela le silafalitsoe haholo ke lintho tse phelang, hobane boholo ba pore bo eketseha ka ho hlatsoa, 'me ho sa tsotellehe hore na ke tharollo ea mofuta ofe e sebelisoang, tlhahiso ea metsi le khatello ka mor'a ho hloekisa li ke ke tsa tšoana le lera le lecha.
Hlatsoa lesela le lecha
- Kamora ho kenya likarolo tsa lera, sistimi e ncha e hloka ho hlatsuoa ka botlalo ho tlosa litšila tsohle tse setseng, li-solvents le mekelikeli e sireletsang sistimi.
- Ha o sebelisa metsi a hlahisitsoeng bakeng sa ho noa, a hloka ho hlatsuoa bonyane lihora tse 24.
- Pele o qala tsamaiso, valve ea metsi e tsitsitseng e lokela ho bolokoa e bulehile ka ho feletseng. Ka mor'a hore tsamaiso e qale, valve ea metsi e tsitsitseng e ka koaloa butle-butle le butle-butle ho finyella tekanyo e behiloeng ea ho hlaphoheloa. Ho thibetsoe ka thata ho qala lisebelisoa ha valve ea metsi e tsitsitseng e koetsoe.
- Nakong ea ts'ebetso ea sistimi, li-valve tse holim'a lipeipi tsa tlhahiso ea metsi ha lia tlameha ho koaloa ka nako efe kapa efe (ho kenyeletsoa pele ho ts'ebetso, ts'ebetso ea tloaelo, ho hlatsoa le ho hloekisa lik'hemik'hale tsa sistimi).
- Pele o etsa opereishene e nang le khatello e phahameng, etsa hore moea o tsoe ka mokhoa o bonolo oa ho qala kapa ho laola lebelo la maqhubu ho ntša moea.
