Aluminium sulfate e le coagulant ho hloekisa metsi a litšila

Matsatsing ana, bareki ba bangata ba na le litlhoko tse phahameng le tse phahameng tsa aluminium sulfate, kahoo k'hamphani ea rona e ile ea etela bareki ba bang.Re fumane hore leha ho na le litaelo, batho ba bang ba ntse ba sa utloisise hantle, ’me ba iphapanyetsa lintlha tse ling tse lokelang ho eloa hloko.Kajeno, mohlophisi o tla buisana le uena ka aluminium sulfate e le coagulant.

Aluminium sulfate e loketse feela boholo ba asiti, aluminium sulfate e se nang tšepe e ka sebelisoa bakeng sa maemo a acidic le a sa nke lehlakore, ho bola ha sistimi ho fokotsehile haholo, mme kalafo ea metsi a masoeu e tla ba bonolo;polyaluminium chloride e ka sebelisoa mefuteng e sa nke lehlakore kapa ea alkaline Boloka tefiso e batlang e le ntle, ho e-na le ho theha Al(OH) 3 precipitates kapele joalo ka sehlahisoa sena, le ka lebaka la pre-hydrolysis ea polyaluminium chloride, pH boleng ba sistimi. e ke ke ea theoha haholo.

Aluminium sulfate e batla e tsitsitse moeeng.Ha e le 86.5, e tla lahleheloa ke karolo ea metsi a crystallization, 'me ha e le 250, e tla lahleheloa ke metsi ohle a crystallization.Ha e futhumatsoa, ​​e atoloha ka matla 'me e fetoha seponche.Ha e chesoa e le khubelu, e fetoha sulfur trioxide le aluminium oxide.E na le maemo a leholimo ha mongobo o lekanyelitsoeng o ka tlase ho 25%.Matsoai a sa qhibiliheng a theoha ka mor'a ho belisa nako e telele.Ho feta moo, ho kopantsoe le phello ea phekolo ea metsi a aluminium sulfate holim'a metsi a litšila a turbid, polyaluminium chloride e ka boela ea finyella phello ea ho tlosa moferefere, esita le ho potlakisa nako ea ho finyella phello ea ho tlosoa ha turbidity, empa hobane theko ea eona e lekanyelitsoeng e batla e phahame le nako ea ho tlosa turbidity ha e telele haholo.Ha ho bapisoa le ferrous sulfate, seretse se entsoeng ka letsoai la aluminium se teteaneng, se ka fokotsang haholo litšenyehelo tsa ho phekola seretse.

Selelekela se ka holimo se amana le aluminium sulfate.Ho ka bonoa ho tsoa ka holimo hore ho nepahetse ho sebelisa aluminium sulfate e le coagulant ha ho phekoloa metsi a litšila a litšila.Haeba u ntse u sa utloisise letho, ka kopo ikopanye le rona ka kotloloho.
