I-Aluminium chlorohydrate (ACH) ne-polyaluminium chloride (PAC) zibonakala zingamakhemikhali amabili ahlukene asetshenziswa njengeama-flocculants ekwelapheni amanzi. Eqinisweni, i-ACH ime njengento egxile kakhulu emndenini we-PAC, iletha okuqukethwe okuphezulu kwe-alumina kanye nokuyisisekelo okungafinyeleleka ngamafomu aqinile noma amafomu esixazululo azinzile. Laba bobabili banokusebenza okuhlukile okuhlukile, kepha izindawo zabo zokusebenza zihluke kakhulu. Lesi sihloko sizokunikeza ukuqonda okujulile kwe-ACH ne-PAC ukuze ukwazi ukukhetha umkhiqizo olungile.
I-Polyaluminium chloride (PAC) iyi-polymer yemolekyuli ephezulu enefomula yamakhemikhali evamile [Al2(OH)nCl6-n]m. Ngenxa yezakhiwo zayo zamakhemikhali eziyingqayizivele, inohlu olubanzi lwezinhlelo zokusebenza emikhakheni ehlukahlukene.I-Polyaluminium chloride (PAC) idlala indima ebalulekile ekwelapheni amanzi, iqede ngempumelelo izinto eziqinile ezimisiwe, izinto ezingama-colloidal, nezinto eziphilayo ezingancibiliki ngezinqubo zokuhlangana. Ngokuqeda izinhlayiya, i-PAC ikhuthaza ukuhlanganisa, yenza kube lula ukususwa kwazo emanzini. I-PAC, evame ukusetshenziswa eceleni kwamanye amakhemikhali afana ne-PAM, ithuthukisa ikhwalithi yamanzi, inciphisa ukungcola, futhi ihlangabezana nezindinganiso zomkhakha.
Emkhakheni wokwenza amaphepha, i-PAC isebenza njenge-flocculant engabizi kanye ne-precipitant, ethuthukisa ukuhlanzwa kwendle kanye nokulinganisa kwe-rosin-neutral. Ithuthukisa imiphumela yokulinganisa, ivimbele indwangu kanye nokungcoliswa kwesistimu.
Izicelo zePAC zidlulela embonini yezimayini, zisiza ekugezweni kwensimbi nokuhlukaniswa kwezimbiwa. Ihlukanisa amanzi ne-gange, yenza kube lula ukusetshenziswa kabusha, futhi ikhiphe udaka.
Ekukhishweni nasekucwengisisweni kukaphethiloli, i-PAC isusa ukungcola, izinto eziphilayo ezingancibiliki, nezinsimbi emanzini angcolile. Iqeda amandla futhi isuse amaconsi kawoyela, iqinise imithombo yamanzi futhi ivimbele ukulimala kokwakheka ngesikhathi sokumba uwoyela.
Ukuphrinta izindwangu nokudaya kuyazuza ekhonweni le-PAC lokuhlanza amanzi angcolile ngamavolumu amakhulu kanye nokuqukethwe okuphezulu kokungcola kwemvelo. I-PAC ikhuthaza ukuhlanzwa okuqinile, okusheshayo kwezimbali ze-alum, ukufeza imiphumela emangalisayo yokwelapha.
I-ACH, i-Aluminium Chlorohydrate, enefomula yamangqamuzana i-Al2(OH)5Cl·2H2O, iyinhlanganisela ye-polymer engaphili ebonisa izinga eliphezulu le-alkalization uma kuqhathaniswa ne-polyaluminium chloride futhi ilandela kuphela i-aluminium hydroxide. Ithola i-polymerization yebhuloho ngamaqembu e-hydroxyl, okuholela ku-molecule equkethe inani eliphakeme kakhulu lamaqembu e-hydroxyl.
Itholakala ekuhlanzweni kwamanzi nasemabangeni amakhemikhali ansuku zonke (ibanga lezimonyo), i-ACH iza ngamafomu empushana (okuqinile) kanye noketshezi (isixazululo), okuqinile kube yimpushana emhlophe kanye nesixazululo uketshezi olungenambala olubonisa ngale.
I-insoluble matter kanye nokuqukethwe kwe-Fe kuphansi, ngakho-ke kungasetshenziswa ezindaweni zansuku zonke zamakhemikhali.
I-ACH ithola izinhlelo zokusebenza ezihlukahlukene. Isebenza njengezinto ezingavuthiwe zemithi nezimonyo ezikhethekile, ikakhulukazi njengesithako esiyinhloko sokulwa nokujuluka esaziwa ngokusebenza kwayo, ukucasuka okuphansi, nokuphepha. Ngaphezu kwalokho, i-ACH iyabiza ngakho-ke ayivamisile ukusetshenziswa njenge-flocculant emanzini okuphuza kanye nokwelashwa kwamanzi angcolile ezimbonini. I-ACH iphinda ibonise ukujiya okusebenzayo ku-pH spectrum ebanzi kunosawoti wensimbi ovamile kanye ne-low-basin polyaluminium chloride.
