Ekuhlanzweni kwendle, ukusebenzisa i-ejenti yokuhlanza amanzi kuphela kuvame ukwehluleka ukufeza umphumela. I-Polyacrylamide (PAM) kanye ne-polyaluminum chloride (PAC) zivame ukusetshenziswa ndawonye enkambisweni yokuhlanza amanzi. Ngayinye inezimpawu nemisebenzi ehlukile. Isetshenziswa ndawonye ukukhiqiza imiphumela engcono yokucubungula.
1. I-Polyaluminum chloride(I-PAC):
- Umsebenzi oyinhloko uyi-coagulant.
- Kunganciphisa ngempumelelo ukushaja kwezinhlayiya ezilenga emanzini, okubangela ukuthi izinhlayiya zihlangane zakhe ama-floc amakhulu, okwenza kube lula ukuthungwa nokuhluzwa.
- Ifanele izimo ezahlukene zekhwalithi yamanzi futhi inethonya elihle ekususeni ukungcola, umbala kanye nezinto eziphilayo.
2. I-Polyacrylamide(I-PAM):
- Umsebenzi oyinhloko uwukusiza nge-flocculant noma i-coagulant.
- Kungakhulisa amandla kanye nomthamo we-floc, okwenza kube lula ukuhlukana namanzi.
- Kunezinhlobo ezahlukene ezifana ne-anionic, i-cationic kanye ne-non-ionic, futhi ungakhetha uhlobo olufanele ngokwezidingo zakho ezithile zokwelashwa kwamanzi.
Umphumela wokusebenzisa ndawonye
1. Ukuthuthukisa umphumela wokujiya: Ukusetshenziswa okuhlangene kwe-PAC kanye ne-PAM kungathuthukisa kakhulu umphumela wokujiya. I-PAC kuqala iqeda amandla ezinhlayiya ezilengisiwe emanzini ukuze zakhe ama-floc okuqala, kanti i-PAM ithuthukisa amandla kanye nomthamo wama-floc ngokubopha kanye nokumuncwa, okwenza kube lula ukuzinza nokususa.
2. Thuthukisa ukusebenza kahle kokwelashwa: Ukusebenzisa i-PAC noma i-PAM eyodwa kungase kungafezi umphumela omuhle kakhulu wokwelashwa, kodwa inhlanganisela yakho kokubili inganikeza ukusebenza okugcwele ezinzuzweni zakho, ithuthukise ukusebenza kahle kokwelashwa, inciphise isikhathi sokusabela, inciphise umthamo wamakhemikhali, ngaleyo ndlela inciphise izindleko zokwelashwa.
3. Ukuthuthukisa ikhwalithi yamanzi: Ukusetshenziswa okuhlangene kungasusa kangcono izinto eziqinile ezilengayo, ukungcoliswa kanye nezinto eziphilayo emanzini, futhi kuthuthukise ukucaca kanye nobumsulwa bekhwalithi yamanzi angcolile.
Izinyathelo Zokuqapha Ekusetshenzisweni Okusebenzayo
1. Ukulandelana kokungeza: Ngokuvamile i-PAC ifakwa kuqala ukuze kuhlanganiswe i-preliminary, bese kuba i-PAM ukuze kuhlanganiswe i-flocculation, ukuze kwandiswe ukusebenzisana phakathi kwalokhu okubili.
2. Ukulawulwa kwesilinganiso: Isilinganiso se-PAC ne-PAM sidinga ukulungiswa ngokwezimo zekhwalithi yamanzi kanye nezidingo zokwelashwa ukuze kugwenywe ukumosha kanye nemiphumela emibi ebangelwa ukusetshenziswa ngokweqile.
3. Ukuqapha ikhwalithi yamanzi: Ukuqapha ikhwalithi yamanzi kufanele kwenziwe ngesikhathi sokusetshenziswa, futhi umthamo wamakhemikhali kufanele ulungiswe ngesikhathi ukuqinisekisa umphumela wokwelashwa kanye nekhwalithi yokungcola.
Ngamafuphi, ukusetshenziswa okuhlangene kwe-polyacrylamide ne-polyaluminum chloride kungathuthukisa kakhulu umphumela wokwelashwa kwamanzi, kodwa umthamo othize kanye nendlela yokusebenzisa kudingeka kulungiswe ngokwesimo sangempela.
