In Ukwelashwa Kwamanzi Angcolile Ezimbonini, kuzoba nezinhlayiya ezincane eziningi ezilenga emanzini angcolile. Ukuze ususe lezi zinhlayiya futhi wenze amanzi acwebe futhi asetshenziswe kabusha, kubalulekile ukusebenzisaIzithasiselo Zamakhemikhali Amanzi -Ama-Flocculant (I-PAM) ukwenza lezi zinhlayiya ezilengayo Ukungcola kubumbana kube ama-molecule amakhulu bese kuhlala phansi.
Izinhlayiya ze-colloid emanzini zincane, futhi ubuso buyamanziswa futhi bushajwe ukuze buzinze. Ngemva kokuba i-flocculant ingeziwe emanzini, iyashiswa ibe yi-colloid eshajwe kanye nama-ion ayo azungezile ukuze kwakhiwe ama-micelle anesakhiwo sikagesi esinezingqimba ezimbili.
Indlela yokuxuba ngokushesha ngemva kokufaka umthamo isetshenziswa ukukhuthaza amathuba kanye nenani lokushayisana phakathi kwezinhlayiya zokungcola kwe-colloidal emanzini kanye nama-micelles akhiwe yi-hydrolysis ye-flocculant. Izinhlayiya zokungcola emanzini ziqala zilahlekelwe ukuzinza kwazo ngaphansi kwesenzo se-flocculant, bese zihlangana zibe izinhlayiya ezinkulu, bese zihlala phansi noma zintanta phezulu endaweni yokuhlukanisa.
Umkhiqizo we-GT we-velocity gradient G okhiqizwa ngokushukumisa kanye nesikhathi sokushukumisa i-T ungamela ngokungaqondile inani eliphelele lokushayisana kwezinhlayiya kuso sonke isikhathi sokusabela, futhi umphumela wokusabela kokujiya ungalawulwa ngokushintsha inani le-GT. Ngokuvamile, inani le-GT lilawulwa phakathi kuka-104 no-105. Uma kucatshangelwa ithonya lokujiya kwezinhlayiya zokungcola ekushayisaneni, inani le-GTC lingasetshenziswa njengepharamitha yokulawula ukuchaza umphumela wokujiya, lapho u-C emele ukujiya kwezinhlayiya zokungcola emanzini angcolile, futhi kunconywa ukuthi inani le-GTC libe phakathi kuka-100 noma ngaphezulu.
Inqubo yokushukumisela i-flocculant ukuthi isakazeke ngokushesha emanzini futhi ixubane ngokulinganayo nawo wonke amanzi angcolile ibizwa ngokuthi ukuxuba. Izinhlayiya zokungcola emanzini ziyasebenzisana ne-flocculant, futhi ngezindlela ezifana nokucindezelwa kwengqimba ephindwe kabili kagesi kanye nokungaguquguquki kukagesi, ukuzinza kuyalahleka noma kuncishiswe, kanti inqubo yokwakha ama-micro floc ibizwa ngokuthi i-coagulation. Inqubo yokuhlanganisa kanye nokwakheka kwama-micro floc akhula abe ama-floc amakhulu ngezindlela ezifana ne-adsorption bridging kanye ne-sediment net capture ngaphansi kokushukunyiswa kwezinto ezihlanganisa ama-bridging kanye nokugeleza kwamanzi ibizwa ngokuthi i-flocculation. Ukuxuba, ukuhlanganisa kanye ne-flocculation kubizwa ngokuthi i-coagulation. Inqubo yokuxuba ngokuvamile iqedwa ethangini lokuxuba, futhi ukuhlanganisa kanye ne-flocculation kwenziwa ethangini lokusabela.
Mayelana nokusetshenziswa kweI-Polyacrylamidekanye nokugeleza kwayo, ungaxhumana ne-Ukwenziwa Kwamakhemikhali Amanziukuze ufunde kabanzi
