Nakong ea ts'ebetso ea 'mabole le lisebelisoa tse ling tsa majoe, metsi a litšila a hlahisoang a na le phofo e ngata ea majoe le pholiso. Haeba metsi ana a litšila a ntšoa ka ho toba, a ke ke a baka tšenyo ea mehloli ea metsi feela, empa hape a tla silafatsa tikoloho ka botebo. Ho rarolla bothata bona, k'hamphani e itseng e sebetsanang le lejoe e sebelisa mokhoa oa ho theola lik'hemik'hale, o kopantsoeng le polyaluminium chloride (PAC) le polyacrylamide (PAM), e kopantsoe lelisebelisoa tsa khatiso ea sefa, ho finyella phekolo e sebetsang le ho tsosolosoa ha likhoerekhoere, ha ho ntse ho etsoa melemo e meng ea moruo.
1. Litšobotsi le mathata a kalafo ea likhoerekhoere
Metsi a litšila a sebetsanang le 'mabole a na le litšobotsi tsa lintho tse tiileng tse emisitsoeng haholo le sebopeho se rarahaneng. Likaroloana tse ntle tsa phofo ea majoe li thata ho lula ka tlhaho, 'me se pholileng se na le lik'hemik'hale tse sa tšoaneng tse kang li-surfactants, rust inhibitors, joalo-joalo, tse eketsang bothata ba ho hloekisa metsi a litšila. Haeba e sa hloekisoe hantle, lintho tse tiileng tse fanyehiloeng ka har'a likhoerekhoere li tla koala liphaephe, 'me lik'hemik'hale tse ka har'a pholileng li tla silafatsa mobu le metsi.
2, Filter e ntse e tsoela pele ho sebetsa
K'hamphani e kentse mechine e hatisang e sebetsang hantle haholo tsamaisong ea likhoerekhoere. Ntlha ea pele, eketsa polyaluminium chloride le polyacrylamide ka har'a linkho tsa dosing tse fanoeng ka mochine oa khatiso, 'me u qhale le ho li hlohlelletsa ka tekanyo e itseng. Sethethefatsi se qhibilihisitsoeng se laoloa ka nepo ke pompo ea dosing ho isa tanka e kopanyang ea mochini o hloekisang. Ka tanka ea ho kopanya, lik'hemik'hale li kopantsoe ka ho feletseng le likhoerekhoere, 'me li-coagulation le flocculation reactions li etsahala ka potlako. Ka mor'a moo, mokelikeli o tsoakiloeng o kena ka kamoreng ea filthara ea mochine oa khatiso, 'me tlas'a khatello, metsi a ntšoa ka lesela la sefe, ha sediment e koaletsoe ka kamoreng ea ho hloekisa. Ka mor'a nako ea ho hloekisa khatello, ho etsoa kaka ea seretse e nang le mongobo o fokolang, e finyellang karohano e sebetsang ea ho tiea le metsi.
Ka kakaretso, ts'ebeliso ea mokhoa oa ho theola boima ba lik'hemik'hale, o kopantsoeng le polyaluminium chloride le polyacrylamide, 'me o kopantsoe le lisebelisoa tsa khatiso ea filthara ho phekola metsi a litšila a entsoeng ka 'mabole ke tharollo e sebetsang hantle, ea moruo, le tikoloho e nang le boleng bo botle ba papatso.
