Txhawm rau kom zoo dua flocculate thiab precipitate polyaluminum chloride, hom polyaluminum chloride yuav tsum tau xaiv ua ke nrog cov dej zoo ntawm cov dej phwj tuaj. Tsuas yog los ntawm kev nrhiav hom zoo tuaj yeem ua tiav ob zaug qhov txiaj ntsig nrog ib nrab ntawm kev siv zog. Hauv qab no, polyaluminium chloride manufacturers yuav tshuaj xyuas plaub txheej txheem ntawm polyaluminium chloride hauv cov txheej txheem dej tsim nyog.
Kev daws teeb meem ntawm PAC polyaluminium chloride flocculant: nws yog txheej txheem ntawm floc nyob hauv lub tank, uas yuav tsum tau ua kom qeeb dej. Txhawm rau txhim kho qhov ua tau zoo, lub raj inclined (phaj hom) lub tank yog feem ntau siv (cov txheej txheem huab cua flotation yog siv los cais cov flocs). ), ntau cov paj tuab tuab yog thaiv los ntawm cov phab ntsa ntawm cov yeeb nkab inclined (phaj) thiab sib sau rau hauv qab ntawm lub pas dej, cov txheej txheej sab saud yog cov dej ntshiab, thiab cov paj uas tseem tshuav nrog cov khoom me me thiab qhov ntom ntom me me. nqis thaum tseem sib tsoo. Cov residual turbidity tsis hloov kiag li. Lub beaker xeem yuav tsum tau qeeb ntawm 20-30 rpm rau 5 feeb, thiab tom qab ntawd ntsiag to rau 10 feeb los ntsuas qhov seem turbidity.
