Njenge-coagulant esetshenziswa kabanzi emkhakheni wokwelashwa kwamanzi, i-PAC ibonisa ukuzinza kwamakhemikhali okuhle kakhulu ekushiseni kwegumbi futhi inobubanzi be-pH yokusetshenziswa okubanzi. Lokhu kuvumela i-PAC ukuthi isabele ngokushesha futhi yakhe izimbali ze-alum lapho iphatha izimfanelo ezahlukahlukene zamanzi, ngaleyo ndlela isuse ngempumelelo ukungcola emanzini. Ekuphathweni kwamanzi amdaka ezimbonini, i-PAC inomthelela omkhulu ekususweni kwezinto eziyingozi njenge-phosphorus, i-ammonia nitrogen, i-COD, i-BOD kanye nama-ion ensimbi esindayo. Lokhu kungenxa kakhulu yamandla okujiya aqinile e-PAC, ekwazi ukubopha lezi zinto eziyingozi zibe yizinhlayiya ezinkulu ngokumunca kanye nokubopha okugoqekayo, okwenza kube lula ukuhlala kanye nokuhlunga okulandelayo.
I-PAM: isikhali esiyimfihlo sokwenza ngcono ukugeleza kwegazi
Isebenzisana ne-PAC, i-PAM idlala indima ebalulekile ekwelapheni amanzi angcolile. Njenge-polymer flocculant, i-PAM ingathuthukisa umphumela we-flocculation ngokulungisa isisindo sayo sama-molecule, i-ionicity kanye ne-ionic degree. I-PAM ingenza ama-floc abe mancane kakhulu futhi yandise ijubane lokuthungwa, ngaleyo ndlela ithuthukise ukucaca kwamanzi. Uma umthamo we-PAM unganele noma ungaphezu kwalokho, ama-floc angase akhululeke, okuholela ekhwalithini yamanzi angcolile.
Ukwahlulela ukusebenza kahle kwe-PAC kanye ne-PAM ngezimo ze-floc
Qaphela usayizi wama-floc: Uma ama-floc emancane kodwa esatshalaliswe ngokulinganayo, kusho ukuthi isilinganiso somthamo we-PAM ne-PAC asihlanganiswanga. Ukuze kuthuthukiswe umphumela, umthamo we-PAC kufanele wandiswe ngendlela efanele.
Hlola umphumela wokubola: Uma izinto eziqinile ezimisiwe zinkulu futhi umphumela wokubola ulungile, kodwa i-supernatant yekhwalithi yamanzi ingcolile, lokhu kubonisa ukuthi i-PAC ayengezwanga ngokwanele noma isilinganiso se-PAM asifanele. Ngalesi sikhathi, ungacabanga ukwandisa umthamo we-PAC ngenkathi ugcina isilinganiso se-PAM singashintshi futhi uqhubeke nokubona umphumela.
Qaphela isimo se-floc: Uma i-floc ijiyile kodwa amanzi enamafu, umthamo we-PAM ungandiswa ngokufanele; uma inhlabathi incane futhi i-supernatant inamafu, kusho ukuthi umthamo we-PAM awanele, futhi umthamo wayo kufanele unyuswe ngokufanele.
Ukubaluleka kokuhlolwa kwembiza (okubizwa nangokuthi ukuhlolwa kwembiza): Ekuhlolweni kwembiza, uma kutholakala udongeni lwembiza, kusho ukuthi kufakwe i-PAM eningi kakhulu. Ngakho-ke, umthamo wayo kufanele wehliswe ngendlela efanele.
Ukuhlolwa kokucaca: Uma izinto eziqinile ezilengayo zincane noma ziqinile, uma i-supernatant icacile kakhulu, kusho ukuthi isilinganiso somthamo we-PAM ne-PAC sinengqondo kakhulu.
Ngamafuphi, ukuze kufezwe umphumela omuhle kakhulu wokugeleza kwamanzi, umthamo we-PAC kanye ne-PAM kumele ulawulwe futhi ulungiswe ngokucophelela. Ngokubuka kanye nokuhlola, singahlulela ngokunembile umphumela wokusetshenziswa kwalokhu okubili, ngaleyo ndlela senze ngcono inqubo yokwelapha indle. Ekusetshenzisweni okungokoqobo, kubalulekile ukucabangela ngokuphelele izimo ezithile zekhwalithi yamanzi, izidingo zokwelashwa, imingcele yemishini kanye nezinye izici ukwakha uhlelo lokulinganisa amakhemikhali olwenzelwe wena. Ngaphezu kwalokho, kufanele kunakwe ngokwanele ukugcinwa, ukuthuthwa kanye nokulungiswa kwe-PAC kanye ne-PAM ukuqinisekisa ukusebenza kahle nokuphepha kwemithi.
