Bohlokoa ba litaba tsa aluminium ka polyaluminium chloride

Sebakeng sa ho hloekisa likhoerekhoere le ho hloekisa metsi, Polyaluminium Chloride ke flocculant e sebelisoang haholo ebile e sebetsa haholo. Har'a matšoao a fapaneng a ho lekola boleng le ts'ebetso ea polyaluminium chloride, ha ho pelaelo hore litaba tsa aluminium oxide ke e 'ngoe ea lintlha tsa bohlokoa ka ho fetisisa. E susumetsa haholo katleho, boholo ba ts'ebeliso, le katleho ea litšenyehelo tsa polyaluminium chloride.

Likahare tsa aluminium ke sesupo sa bohlokoa sa ho lekanya metsoako e sebetsang

Aluminium oxide content ka polyaluminium chloride ke pontšo ea bohlokoa ea likarolo tsa eona tse sebetsang. Ka kakaretso, litaba tse phahameng tsa aluminium oxide li bolela hore polyaluminium chloride e ka etsa flocculation le sedimentation ka matla ho feta.Phekolo ea Metsi. Ha polyaluminium chloride e kenngoa metsing a litšila, aluminium oxide e kena ka hydrolysis le polymerization reactions ka metsing, ho etsa letoto la li-multi-nuclear hydroxyl complexes tse lefshoang haholo. Li-complexes tsena li fokotsa litefiso tse holim'a likaroloana tsa colloidal, li etsa hore li lahleheloe ke botsitso le ho kopana, ho etsa lihlopha tse kholoanyane. Sena se potlakisa ts'ebetso ea sedimentation, ho tlosa lintho tse tiileng tse emisitsoeng, colloidal, le lintho tse ling tse qhibilihisitsoeng metsing. Haeba dikahare tsa aluminium oxide li le tlase, likarolo tse sebetsang tse fumanehang bakeng sa karabelo ha li lekane ka tekanyo e lekanang, ho etsa hore ho be thata ho fihlela phello e lakatsehang ea flocculation. Ka lebaka leo, litšila tse ka har'a metsi a litšila li ke ke tsa e-ba teng ka ho feletseng le ho arohana, ho fokotsa haholo ts'ebetso ea tlhoekiso ea metsi.

Likahare tse fapaneng tsa alumina li khetholla phapang ea mefuta ea ts'ebeliso

Ho ipapisitsoe le maemo a fapaneng a litaba tsa alum, polyaluminium chloride ka kakaretso e ka aroloa ka limaraka tse 'maloa, joalo ka 30%,28%,26% le 24%. Limaraka tse fapaneng li loketse ho phekola litšoaneleho tse fapaneng tsa metsi. Ha ho hloekisoa metsi a litšila a nang le litšila tse ngata, a nang le palo e kholo ea lintho tse tiileng tse emisitsoeng, ho hlokahala hore ho be le alum e phahameng ho finyella flocculation e matla. High-alum-content polyaluminium chloride e ka etsa li-flocs tse kholo ka potlako, e kopanya ka potlako le ho theola litšila ka metsing, ka katleho e fokotsa moferefere oa metsi a litšila. Leha ho le joalo, bakeng sa metsi a litšila a tlaase, ho sebelisa polyaluminium chloride e nang le alum-content e phahameng ho ka etsa hore lintho tse tiileng tse emisitsoeng li se ke tsa thekesela. Sena se bakoa ke hore metsi a litšila a na le asiti e ngata, 'me lihlahisoa tsa polyaluminium chloride tse nang le alum e ngata hangata li na le asiti, e leng se etsang hore ho be thata hore li sebetsane ka katleho le lintho tse ka metsing a litšila. Ho phaella moo, lintho tse tiileng tse ka metsing li ka 'na tsa e-ba bobebe haholo,' me polyaluminium chloride e phahameng ea concentration e ke ke ea khona ho li khanna hore li lule. Ka hona, ha ho phekoloa metsi a litšila a tlaase-turbidity, ho loketse haholo ho khetha polyaluminium chloride e nang le alum e batlang e le tlaase.

Likahare tsa aluminium li ama katleho ea litšenyehelo

Ho latela pono ea tlhahiso, litaba tsa alumina li amana haufi-ufi le litšenyehelo tsa tlhahiso. Ho hlahisa polyaluminium chloride ea boleng bo phahameng ba aluminium ho hloka lisebelisoa tse tala tsa boleng bo holimo le mekhoa e nepahetseng ea tlhahiso, e leng ho eketsang litšenyehelo tsa tlhahiso. Leha ho le joalo, lits'ebetsong tse sebetsang, litaba tsa alumina tse phahameng ha se kamehla li leng betere; ho bohlokoa ho nahana ka litšenyehelo le katleho ea kalafo. Nakong ea phekolo ea metsi a litšila, ho latela ka bofofu polyaluminium chloride e phahameng ea aluminium ntle le ho nahana ka boleng ba sebele ba metsi ho ka lebisa litšenyehelong tse eketsehileng tsa phekolo 'me ho ka' na ha hlōleha ho finyella liphello tse nepahetseng. Ka hona, ho khetha polyaluminium chloride e nang le lisebelisoa tse nepahetseng tsa alumina ho netefatsa phekolo e sebetsang ea metsi ha ho ntse ho fokotsa litšenyehelo, kahoo ho eketsa katleho ea litšenyehelo.

Ka bokhutšoanyane, aluminium oxide content ka polyaluminium chloride ke ea bohlokoa haholo ho hloekisa metsi a litšila le ho hloekisa metsi. Ha se feela sesupo sa bohlokoa bakeng sa ho lekola likarolo tse sebetsang tsa polyaluminium chloride empa hape e etsa qeto ea hore na sehlahisoa se sebetsa joang le katleho ea sona. Lits'ebetsong tse sebetsang, ke habohlokoa ho khetha ka saense le ka mokhoa o utloahalang lihlahisoa tsa polyaluminium chloride tse nang le dikahare tse nepahetseng tsa aluminium oxide tse thehiloeng ho maemo a fapaneng a boleng ba metsi ho finyella liphello tse ntle tsa phekolo ea metsi le melemo ea moruo.
