Polycrylamide(UPam) uyi-hydrophilic solwentic polymer esetshenziswa kabanzi ezinqubweni zokwelashwa kwamanzi. Isetshenziswa ngokuyinhloko njenge-flocculant futhi i-ejenti yamakhemikhali ebangela izinhlayiya ezimisiwe emanzini ukuba ihlanganise ama-flocs amakhulu, ngakusiza ukususwa kwazo ngokucaciswa noma ekuhlunga. Ngokuya ngekhwalithi yamanzi amdaka, sebenzisa i-cationic, anionic, noma i-onic pam. I-PolyAcrylamide inikezela ngezinzuzo eziningana ekwelashweni kwamanzi, kufaka phakathi ukusebenza kwayo ngohlu olubanzi lwe-pH, lokushisa, kanye namabanga okubangela. Umphumela we-Cooagition ungahlolwa kusetshenziswa izivivinyo ze-jar noma ukulinganiswa kwe-turbidity.
I-PolyAcrylamide ingasetshenziswa kabanzi ekwelashweni kwamanzi kwezimboni, ekwelashweni kwendle, njll. Ezitshalweni zokwelashwa kwamanzi, ama-polyracrylamide asetshenziswa ngezinqubo ezahlukahlukene, kufaka phakathi ukucaciswa kwamabanga aphansi kanye nokuhlunga, kanye negciwane. Ngesikhathi senqubo yokuqala yokucacisa, yengezwa kumanzi aluhlaza ukukhuthaza ukulungiswa kwama-solids amisiwe, asuswe yi-sedimentation noma nge-flotation. Ekucacisweni kwesibili, i-polyyamide isetshenziselwa ukucacisa namanzi aphethwe ngokususa ama-solidi asamisiwe asamisiwe kanye nezinkulungwane ze-adposi.
Umgomo osebenzayo weI-PolyacryRlamide Flocculontyilena: Ngemuva kokungeza isixazululo se-pam, ama-pam adsbs kwizinhlayiya, akha amabhuloho phakathi kwawo. Echibini lokuqala, linamathela ukwakha ama-flocs amakhulu, futhi umzimba wamanzi uba yi-turbid ngalesi sikhathi. Ngemuva kokuthi inani elikhulu lama-flocs likhule futhi libe mkhulu, lizohamba lihambe kancane ngokuhamba kwesikhathi, futhi ungqimba olungaphezulu lwamanzi aluhlaza luzocacisa. Le nqubo yokuhlalela ithuthukisa izici zokuxazulula izinhlayiya, okwenza kube lula ukususa ngesikhathi sokucaciswa noma sokuhlunga. I-PolyAcrylamide imvamisa isetshenziswa ngokuhlanganiswa namanye ama-coabulants nama-flocculants ukufezekisa ukucaciswa okuhle nokuhlunga kokusebenza.
I-PolyAcrylamide nayo idlala indima ebalulekile ekuhlutjweni kwamanzi. Imvamisa isetshenziswa njengesihlungi sangaphambi kokuhlunga noma kwezinye izindlela zokuhlunga ngokomzimba ukususa ama-solids amisiwe kanye ne-turbidity. Ngokwenza ngcono ukususwa kwalezi zinhlayiya, i-polylacrylide isiza ukuqinisekisa i-filtrate ecacile, esothile.
I-PolyAcrylamide iyi-polymer eqinile futhi engeyona into enobuthi eyehlela ngezinqubo zemvelo noma izindlela zokwelashwa okuphilayo. Kumele kwaziwe ukuthi isixazululo esichithekile sizokwenza ukuthi isitezi sisheshe kakhulu, esingaholela ekuweni.
Kodwa-ke, inani le-PAM elisetshenzisiwe lincike ohlotsheni lwamanzi angcolile kanye nokuqukethwe kwezinhlayiya eziqinile ezimisiwe, kanye nokuba khona kwamanye amakhemikhali, ama-acid, kanye nokungcola emanzini. Lezi zinto zingathinta umphumela wokuhlangana wePam, ngakho-ke ushintsho olunengqondo ludinga ukwenziwa ngesikhathi sokusetshenziswa. Imikhiqizo ye-PAM enezinsimbi ezihlukile zamangqamuzana, ama-inic degrees, kanye nemithamo kufanele ikhethwe ngokucophelela ngezinhlobo ezahlukene zamanzi amdaka.
