In Ukwelashwa kwamanzi wezimboni, kuzoba nezinhlayiya eziningi eziningi ezimisiwe emanzini angcolile. Ukususa lezi zinhlayiya futhi wenze amanzi acace futhi asetshenziswe kabusha, kuyadingeka ukuyisebenzisaIzithasiselo zamakhemikhali zamanzi -Ama-Flocculatants (Upombolo) Ukwenza lezi zinhlayiya zokuthi ukungcola kwezinhlayiya ezimisiwe zigxile kumamolekyuli anobuningi futhi ahlale phansi.
Izinhlayiya ze-colloid emanzini zincane, futhi ingaphezulu liyachitheka futhi libhekene necala lokubenza zinzile. Ngemuva kokuthi i-flocculant ingezwe emanzini, ihlelwe nge-colloid ekhokhisiwe kanye nama-ion azungezile ukwakha ama-micelles ngesakhiwo sesendlalelo sikagesi esiphindwe kabili.
Indlela yokuvuselela ngokushesha ngemuva kokutholwa kwe-dosing ukukhuthaza ithuba nenombolo yokushayisana phakathi kwezinhlayiya zokungcola ezivuthayo emanzini kanye neMicelletes ezakhiwe yi-hydrolysis ye-flecculant ye-flocculant. Izinhlayiya zokungcola emanzini kuqala zilahlekelwa ukuqina kwazo ngaphansi kwesenzo se-flecculant, bese sihlanganisa omunye komunye abe izinhlayiya ezinkulu, bese sihlala phansi noma sithengele endaweni yokuhlukanisa.
Umkhiqizo we-GT we-velocity gradient g ekhiqizwa ngokuvusa kanye nesikhathi sokuvuselela i-T kungamelela ngokungaqondile inani eliphelele lokushayisana kwezinhlayiyana kulo lonke isikhathi sokuphendula, kanye nomphumela wokuphendula we-cooration ungalawulwa ngokushintsha ukushintsha inani le-GT. Ngokuvamile, inani le-GT lilawulwa phakathi kuka-104 no-105. Uma ucabanga ngethonya lokungcola kwenhlaka izinhlayiya ngokushayisana, lapho c lungasetshenziswa njenge-control parameter yokuqothula izinhlayiya zokukhuculula indle, futhi kunconywe ukuthi inani le-GTC libe phakathi kuka-100 noma ngaphezulu.
Inqubo yokuhambisa i-flocculant ukuze isebenzise ngokushesha emanzini futhi ihlanganiswe ngokulinganayo nawo wonke amanzi angcolile abizwa ngokuthi ukuxuba. Izinhlayiya zokungcola emanzini zisebenzisana ne-flocculant, futhi ngezindlela ezifana nokucindezelwa kwesendlalelo sogesi kagesi kanye nokungathathi hlangothi kukagesi, ukuqina kulahlekile noma kuncishiswe, futhi inqubo yokwakha ama-flocs amancane ibizwa ngokuthi ama-coagition. Inqubo yokuqokwa kanye nokwakheka kwama-flocs amancane akhula abe yi-flocs enkulu ngokusebenzisa izindlela zokubopha kanye nokuthwebula kwe-sediment net ngaphansi kokuphazamiseka kwezinto zokuphazamiseka nokugeleza kwamanzi kubizwa ngokuthi yi-floccation. Ukuxuba, ukubheja kanye ne-floccation kubizwa ngokuthi ukuhlangana. Inqubo yokuxuba ngokuvamile igcwaliswe ethangini lokuxuba, futhi ukubheja kanye ne-floccution kwenziwa ethangi lokuphendula.
Mayelana nokusetshenziswa kwePolycrylamidekanye ne-floccution yayo, ungaxhumana neUkukhiqizwa kwamakhemikhali wamanziUkuze ufunde kabanzi
