I-PAM Flocculant: umkhiqizo wamakhemikhali onamandla wokwelashwa kwamanzi ezimbonini

I-Polyacrylamide(PAM) i-hydrophilic synthetic polymer esetshenziswa kabanzi ezinqubweni zokwelashwa kwamanzi. Ngokuyinhloko isetshenziswa njenge-flocculant kanye ne-coagulant, i-ejenti yamakhemikhali ebangela izinhlayiya ezimisiwe emanzini ukuthi zihlangane zibe ama-floc amakhulu, ngaleyo ndlela kusize ukususwa kwazo ngokucaciswa noma ngokuhlunga. Ngokuya ngekhwalithi yamanzi angcolile, sebenzisa i-cationic, i-anionic, noma i-PAM engeyona i-ionic. I-Polyacrylamide inikeza izinzuzo ezimbalwa ekwelashweni kwamanzi, okuhlanganisa ukusebenza kahle kwayo phezu kwebanga elibanzi le-pH, izinga lokushisa, nobubanzi be-turbidity. Umthelela we-coagulation ungahlolwa kusetshenziswa izivivinyo zeJar noma ukulinganisa i-turbidity.

I-Polyacrylamide ingasetshenziswa kabanzi ekwelapheni amanzi ezimbonini, ukuthuthwa kwendle, ukuthuthwa kwamanzi angcolile, njll. Ezitshalweni zokwelapha amanzi, i-polyacrylamide isetshenziswa ezinqubweni ezihlukahlukene, kuhlanganise nokucaciswa okuyisisekelo nesesibili, ukuhlunga, nokubulala amagciwane. Phakathi nenqubo yokucacisa okuyinhloko, yengezwa emanzini aluhlaza ukuze kuthuthukiswe ukuhlaliswa kwezinto eziqinile ezimisiwe, ezisuke zisuswe ngokufakwa kwenhlabathi noma ukuntanta. Ekucaciseni okwesibili, i-polyacrylamide isetshenziselwa ukuqhubeka nokucacisa amanzi ahlanzekile ngokususa okuqinile okusele okumisiwe kanye nezinto eziphilayo ezikhangisiwe.

Umgomo wokusebenza wei-polyacrylamide flocculantiwukuthi: ngemva kokungeza isisombululo se-PAM, i-PAM ikhangisa ezinhlayiyeni, yenza amabhuloho phakathi kwazo. Echibini langempela, inamathela ekwakheni ama-flocs amakhulu, futhi umzimba wamanzi uba ne-turbid ngalesi sikhathi. Ngemva kokuba inani elikhulu lezinhlanzi likhula futhi libe likhudlwana, zizofuduka futhi zicwiliswe kancane kancane ngokuhamba kwesikhathi, futhi ungqimba olungaphezulu lwamanzi aluhlaza luzocaca. Le nqubo yokuhlanganisa ithuthukisa izici zokuxazulula izinhlayiya, okwenza kube lula ukuzikhipha ngesikhathi sokucaciswa noma ukuhlunga. I-Polyacrylamide ivame ukusetshenziswa ngokuhlanganiswa namanye ama-coagulants nama-flocculants ukuze kuzuzwe ukucaciswa okuphelele nokusebenza kokuhlunga.

I-Polyacrylamide nayo idlala indima ebalulekile ekuhlungeni amanzi. Ivamise ukusetshenziswa njengesihlungi sangaphambili kuzihlungi noma ezinye izindlela zokuhlunga ezingokoqobo ukuze kususwe okuqinile okumisiwe kanye ne-turbidity. Ngokwenza ngcono ukususwa kwalezi zinhlayiya, i-polyacrylamide isiza ukuqinisekisa ukucwenga okucacile, okuhlanzekile.

I-Polyacrylamide iyi-polymer ezinzile futhi engenabo ubuthi ephuka ngezinqubo zemvelo noma izindlela zokwelapha zebhayoloji. Kumele kuqashelwe ukuthi isixazululo esichithiwe sizobangela ukuthi phansi kusheleleke kakhulu, okungase kuholele ekuweni.

Kodwa-ke, inani le-PAM elisetshenzisiwe lincike ohlotsheni lwamanzi angcolile kanye nokuqukethwe kwezinhlayiya eziqinile ezimisiwe, kanye nokuba khona kwamanye amakhemikhali, ama-acids, nokungcola emanzini. Lezi zici zingase zithinte umphumela wokuhlanganisa we-PAM, ngakho-ke ukulungiswa okufanele kwenziwe ngesikhathi sokusetshenziswa. Imikhiqizo ye-PAM enezisindo zamangqamuzana ahlukene, amadigri e-ionic, nemithamo kufanele ikhethwe ngokucophelela ngezinhlobo ezahlukene zamanzi angcolile.
