I-aluminium chlorohydrate (ACH) kanye ne-polyaluminum chloride (PAC) kubonakala sengathi ziyizinhlanganisela ezimbili ezihlukene zamakhemikhali ezisetshenziswa njenge-ama-flocculant ekwelapheni amanziEqinisweni, i-ACH imele njengento egxile kakhulu emndenini we-PAC, iletha okuqukethwe okuphezulu kakhulu kwe-alumina kanye nobulula obungatholakala ngezindlela eziqinile noma ezinhlotsheni zesisombululo esizinzile. Lezi ezimbili zinezici ezithile ezihlukile kancane, kodwa izindawo zazo zokusebenzisa zihlukile kakhulu. Lesi sihloko sizokunikeza ukuqonda okujulile kwe-ACH ne-PAC ukuze ukwazi ukukhetha umkhiqizo ofanele.
I-Polyaluminum chloride (PAC) iyi-polymer yama-molecule aphezulu enefomula yamakhemikhali ejwayelekile [Al2(OH)nCl6-n]m. Ngenxa yezakhiwo zayo zamakhemikhali ezihlukile, inezinhlobo eziningi zezicelo emikhakheni eyahlukahlukene. I-Polyaluminum chloride (PAC) idlala indima ebalulekile ekwelapheni amanzi, isusa ngempumelelo izinto eziqinile ezimisiwe, izinto ze-colloidal, kanye nezinto eziphilayo ezinganyibiliki ngezinqubo zokuxubana. Ngokususa izinhlayiya, i-PAC ikhuthaza ukuhlangana, ilula ukususwa kwazo emanzini. I-PAC, evame ukusetshenziswa kanye namanye amakhemikhali afana ne-PAM, ithuthukisa ikhwalithi yamanzi, inciphisa ukungcoliswa kwamanzi, futhi ihlangabezana nezindinganiso zemboni.
Emkhakheni wokwenza amaphepha, i-PAC isebenza njenge-flocculant engabizi kakhulu futhi ebangela umonakalo, ithuthukisa ukwelashwa kwendle kanye nosayizi ongathathi hlangothi we-rosin. Ithuthukisa imiphumela yosayizi, ivimbela ukungcoliswa kwendwangu kanye nohlelo.
Izicelo ze-PAC zifinyelela embonini yezimayini, zisiza ekuhlanzweni kwe-ore kanye nokuhlukaniswa kwamaminerali. Ihlukanisa amanzi ne-gangue, yenza kube lula ukusebenzisa kabusha, futhi ikhiphe amanzi odakeni.
Ekukhishweni nasekuhlanzweni kukaphethiloli, i-PAC isusa ukungcola, izinto eziphilayo ezinganyibiliki, kanye nezinsimbi emanzini angcolile. Isusa futhi isuse amaconsi kaphethiloli, izinzise imisele yamanzi futhi ivimbele ukulimala kokwakheka ngesikhathi sokumba uwoyela.
Ukunyathelisa nokufaka imibala kwezindwangu kuzuza ekhonweni le-PAC lokwelapha amanzi angcolile ngobuningi obukhulu kanye nokuqukethwe okuphezulu kokungcola kwemvelo. I-PAC ikhuthaza ukuqina okusheshayo kwezimbali ze-alum, okufeza imiphumela emihle yokwelapha.
I-ACH, i-Aluminium Chlorohydrate, enefomula yama-molecule i-Al2(OH)5Cl·2H2O, iyinhlanganisela ye-polymer engaphili ekhombisa izinga eliphezulu le-alkaliization uma kuqhathaniswa ne-polyaluminum chloride futhi ilandela i-aluminium hydroxide kuphela. Idlula ku-bridge polymerization ngamaqembu e-hydroxyl, okuholela ekutheni i-molecule iquke inani eliphakeme kakhulu lamaqembu e-hydroxyl.
Itholakala emazingeni okwelashwa kwamanzi kanye namakhemikhali ansuku zonke (izinga lobuhle), i-ACH iza ngezindlela zempuphu (eqinile) kanye nesisombululo (isixazululo), lapho okuqinile kuyimpuphu emhlophe kanti isisombululo siyimpuphu ekhanyayo engenambala.
Izinto ezinganyibiliki kanye nokuqukethwe kwe-Fe kuphansi, ngakho-ke kungasetshenziswa emikhakheni yamakhemikhali yansuku zonke.
I-ACH ithola ukusetshenziswa okuhlukahlukene. Isebenza njengezinto zokusetshenziswa kwemithi kanye nezimonyo ezikhethekile, ikakhulukazi njengesithako esiyinhloko sokuvimbela ukujuluka esaziwa ngokusebenza kwayo kahle, ukucasuka okuncane, kanye nokuphepha. Ngaphezu kwalokho, i-ACH iyabiza futhi ngenxa yalokho ayisetshenziswa kakhulu njenge-flocculant emanzini okuphuza kanye nokwelashwa kwamanzi angcolile ezimbonini. I-ACH iphinde ibonise ukujiya okusebenzayo kububanzi be-pH kunosawoti wensimbi ojwayelekile kanye nama-polyaluminum chloride aphansi.
