In Unyango lwamanzi amdaka kwimizi-mveliso, kuya kubakho amasuntswana amaninzi amancinci axhonyiweyo emanzini amdaka. Ukuze ususe la masuntswana kwaye wenze amanzi acace aze asetyenziswe kwakhona, kuyimfuneko ukusebenzisaIzongezo zeKhemikhali zamanzi -Iiflocculants (I-PAM) ukwenza la masuntswana axhonyiweyo Ukungcola kujika kube ziimolekyuli ezinkulu kwaye kuhlale phantsi.
Amasuntswana e-colloid emanzini mancinci, kwaye umphezulu uyamanziswa kwaye utshajwe ukuze uzinze. Emva kokuba i-flocculant yongezwe emanzini, iyatshintshwa ibe yi-colloid etshajiweyo kunye nee-ion ezijikelezileyo ukuze zenze ii-micelles ezinesakhiwo sombane esiphindwe kabini.
Indlela yokuxuba ngokukhawuleza emva kokufaka idosi iyasetyenziswa ukukhuthaza amathuba kunye nenani lokungqubana phakathi kwee-colloidal uncoil particles emanzini kunye nee-micelles ezenziwe yi-hydrolysis ye-flocculant. Ii-punctile uncoils emanzini ziqala zilahlekelwe kukuzinza kwazo phantsi kwesenzo se-flocculant, emva koko zihlangana zibe zii-punctile ezinkulu, zize zihlale phantsi okanye zintante phezulu kwindawo yokwahlula.
Imveliso ye-GT ye-velocity gradient G eveliswa kukuxuba kunye nexesha lokuxuba i-T ingamela ngokungathanga ngqo inani lilonke lokungqubana kwamasuntswana kwixesha lonke lokusabela, kwaye isiphumo se-coagulation reaction sinokulawulwa ngokutshintsha ixabiso le-GT. Ngokubanzi, ixabiso le-GT lilawulwa phakathi kwe-104 kunye ne-105. Ukuqwalasela impembelelo yoxinzelelo lwamasuntswana okungcola kwi-collision, ixabiso le-GTC lingasetyenziswa njengepharamitha yolawulo ukuchaza isiphumo se-coagulation, apho u-C emele uxinzelelo olukhulu lwamasuntswana okungcola kwi-lindle, kwaye kucetyiswa ukuba ixabiso le-GTC libe phakathi kwe-100 okanye ngaphezulu.
Inkqubo yokubangela ukuba i-flocculant isasazeke ngokukhawuleza emanzini ize ixubane ngokulinganayo nawo onke amanzi amdaka ibizwa ngokuba yi-mixing. Amasuntswana angcolileyo emanzini adibana ne-flocculant, kwaye ngeendlela ezifana nokucinezelwa komaleko ombane ophindwe kabini kunye nokungashukumi kombane, uzinzo luyalahleka okanye lunciphe, kwaye inkqubo yokwenza ii-micro floc ibizwa ngokuba yi-coagulation. Inkqubo yokuhlanganiswa kunye nokwenziwa kwee-micro floc ezikhula zibe zii-floc ezinkulu ngeendlela ezifana ne-adsorption bridging kunye ne-sediment net capture phantsi kwe-agitation yezinto ezidibanisa i-bridging kunye nokuhamba kwamanzi ibizwa ngokuba yi-flocculation. Ukuxuba, ukuxinana kunye ne-flocculation zibizwa ngokuba yi-coagulation. Inkqubo yokuxuba ngokubanzi igqitywa kwi-mixing tank, kwaye ukuxinana kunye ne-flocculation kwenziwa kwi-reaction tank.
Malunga nokusetyenziswa kweI-Polyacrylamidekunye nokuxinana kwayo, ungaqhagamshelanaUkuveliswa kweekhemikhali zamanziukufunda okungakumbi
