Kodi PAC imachita chiyani poyeretsa madzi?

Polyaluminium kloride (PAC) imagwira ntchito yofunika kwambiri pakuyeretsa madzi, imagwira ntchito ngati coagulant ndi flocculant. Pamalo oyeretsa madzi, PAC imagwiritsidwa ntchito kwambiri chifukwa cha kusinthasintha kwake komanso kuchita bwino pochotsa zonyansa m'magwero amadzi. Mankhwalawa ndi omwe amathandizira kwambiri pakupanga ma coagulation ndi ma flocculation, zomwe zimathandiza kupititsa patsogolo ntchito zonse zopangira madzi.

Coagulation ndi sitepe yoyamba yopangira madzi, pomwe PAC imawonjezeredwa kumadzi osaphika. Ma aluminium okhala ndi ma aluminium okhala ndi ma AC amapangitsa kuti tinthu tating'ono ting'onoting'ono ting'onoting'ono tigwirizane. Tinthu tating'onoting'ono timeneti timapanga magulu akuluakulu komanso olemera kwambiri, zomwe zimapangitsa kuti zikhale zosavuta kuti zituluke m'madzi panthawi yotsatila. Njira ya coagulation ndiyofunikira pakuchotsa zonyansa za colloidal ndi zoyimitsidwa zomwe sizingasefedwe mosavuta.

Flocculation imatsatira coagulation ndipo imaphatikizapo kugwedezeka pang'ono kapena kusakaniza kwa madzi kulimbikitsa mapangidwe a magulu akuluakulu kuchokera ku tinthu tating'onoting'ono tambirimbiri. PAC imathandizira pagawoli popereka ndalama zowonjezera, kulimbikitsa kugundana ndi kuphatikizika kwa tinthu tating'onoting'ono tomwe timapanga zazikulu komanso zonenepa. Ziphuphuzi zimakhazikika bwino panthawi ya sedimentation, zomwe zimapangitsa kuti madzi azikhala omveka bwino.

Ubwino umodzi wodziwika wa PAC pakuwongolera madzi ndikusinthika kwake kumitundu ingapo yamtundu wamadzi. Imachita bwino m'malo okhala acidic komanso amchere, ndikupangitsa kuti ikhale yoyenera kuthira madzi osiyanasiyana. Kuphatikiza apo, PAC ndiyothandiza pakuthana ndi kusinthasintha kwamadzi ndipo itha kugwiritsidwa ntchito m'njira zosiyanasiyana zochizira madzi, kuphatikiza kuthira madzi akumwa, kuyeretsa madzi m'mafakitale, komanso kuthira madzi oyipa.

PAC imagwira ntchito yofunikira kwambiri pakuyeretsa madzi, kuthandizira kuti madzi aziyenda bwino ndikuchotsa zonyansa m'magwero amadzi. Kusinthasintha kwake, kutsika mtengo, ndi ubwino wa chilengedwe kumapangitsa kukhala chida chofunika kwambiri pofunafuna madzi aukhondo ndi otetezeka. Kumvetsetsa kufunika kwa PAC pakuwongolera madzi kumatsimikizira kufunika kwake pothana ndi zovuta zamtundu wamadzi padziko lonse lapansi.
