I-PAM Flocculant: umkhiqizo wamakhemikhali onamandla wokwelapha amanzi ezimbonini

I-Polyacrylamide(PAM) iyi-polymer yokwenziwa ephilizayo esetshenziswa kabanzi ezinqubweni zokwelashwa kwamanzi. Isetshenziswa ngokuyinhloko njenge-flocculant kanye ne-coagulant, i-chemical agent ebangela ukuthi izinhlayiya ezilenga emanzini zihlangane zibe ama-floc amakhulu, ngaleyo ndlela isize ekususweni kwawo ngokucaciswa noma ukuhlunga. Kuye ngekhwalithi yamanzi angcolile, sebenzisa i-cationic, i-anionic, noma i-non-ionic PAM. I-Polyacrylamide inikeza izinzuzo eziningana ekuphathweni kwamanzi, okuhlanganisa ukusebenza kwayo ngaphezu kobubanzi be-pH, izinga lokushisa, kanye nobubanzi bokugcwala kwamanzi. Umphumela wokugcwala kwamanzi ungahlolwa kusetshenziswa izivivinyo zeJar noma ukulinganisa ukugcwala kwamanzi.

I-Polyacrylamide ingasetshenziswa kabanzi ekuhlanzweni kwamanzi ezimbonini, ekuhlanzweni kwendle, ekuhlanzweni kwamanzi amdaka, njll. Ezitshalweni zokuhlanza amanzi, i-polyacrylamide isetshenziswa ezinqubweni ezahlukahlukene, okuhlanganisa ukucaciswa kokuqala nokwesibili, ukuhlunga, kanye nokubulala amagciwane. Ngesikhathi senqubo yokucaciswa kokuqala, ifakwa emanzini aluhlaza ukuze kukhuthazwe ukuhlaliswa kwezinto eziqinile ezimisiwe, ezibe sezisuswa ngokuthungwa noma ngokuntanta. Ekucacisweni kwesibili, i-polyacrylamide isetshenziselwa ukucacisa amanzi alungisiwe ngokususa izinto eziqinile ezisele ezimisiwe kanye nezinto eziphilayo ezifakwe emanzini.

Umgomo wokusebenza wei-polyacrylamide flocculantyilokhu: ngemva kokufaka isixazululo se-PAM, i-PAM iyanamathela ezinhlayiyeni, yakha amabhuloho phakathi kwazo. Echibini lokuqala, inamathela ukuze yakhe ama-floc amakhulu, futhi umzimba wamanzi uba namafu ngalesi sikhathi. Ngemva kokuba inani elikhulu lama-floc likhule futhi libe likhulu, lizohamba futhi licwile kancane ngokuhamba kwesikhathi, futhi ungqimba olungaphezulu lwamanzi aluhlaza luzocaca. Le nqubo yokuhlanganisa ithuthukisa izici zokuzinza kwezinhlayiyeni, okwenza kube lula ukuzisusa ngesikhathi sokucacisa noma ukuhlunga. I-Polyacrylamide ivame ukusetshenziswa ngokuhlanganiswa nezinye izinto ezihlanganisa ama-coagulant nama-flocculant ukuze kufezwe ukucaca okuhle kanye nokusebenza kokuhlunga.

I-Polyacrylamide nayo idlala indima ebalulekile ekuhlungeni amanzi. Ivame ukusetshenziswa njengesihlungi sangaphambi kokuhlunga ezihlungini noma kwezinye izindlela zokuhlunga ngokomzimba ukususa izinto eziqinile ezilengayo kanye nokungcoliswa kwamanzi. Ngokuthuthukisa ukususwa kwalezi zinhlayiya, i-polyacrylamide isiza ukuqinisekisa ukuhlunga okucacile nokuhlanzekile.

I-Polyacrylamide iyi-polymer eqinile futhi engenabo ubuthi ephuka ngezinqubo zemvelo noma izindlela zokwelapha zebhayoloji. Kufanele kuqashelwe ukuthi isixazululo esichithekile sizokwenza ukuthi phansi kube bushelelezi kakhulu, okungaholela ekuweni.

Kodwa-ke, inani le-PAM elisetshenziswayo lincike ohlotsheni lwamanzi angcolile kanye nokuqukethwe kwezinhlayiya eziqinile ezilengayo, kanye nokuba khona kwamanye amakhemikhali, ama-asidi, kanye nokungcola emanzini. Lezi zici zingathinta umphumela wokujiya kwe-PAM, ngakho-ke kudingeka kwenziwe izinguquko ezifanele ngesikhathi sokusetshenziswa. Imikhiqizo ye-PAM enesisindo sama-molecule ahlukene, ama-ionic degrees, kanye nemithamo kufanele ikhethwe ngokucophelela ngezinhlobo ezahlukene zamanzi angcolile.
