Kodi Poly Aluminium Chloride imachotsa bwanji zoyipitsidwa m'madzi?

Poly Aluminium Chloride(PAC) ndi mankhwala omwe amagwiritsidwa ntchito kwambiri pochiza madzi ndi madzi oipa chifukwa cha mphamvu yake pochotsa zonyansa. Njira yake yochitira zinthu imaphatikizapo njira zingapo zofunika zomwe zimathandiza kuti madzi ayeretsedwe.

Choyamba, PAC imagwira ntchito ngati coagulant mu njira zochizira madzi. Coagulation ndi njira yosokoneza tinthu tating'onoting'ono ta colloidal ndi kuyimitsidwa m'madzi, zomwe zimapangitsa kuti zigwirizane ndikupanga tinthu tambirimbiri totchedwa flocs. PAC imakwaniritsa izi mwa kusokoneza milandu yoyipa pamwamba pa tinthu tating'onoting'ono ta colloidal, zomwe zimawalola kubwera palimodzi ndikupanga flocs kudzera munjira yotchedwa charge neutralization. Ma flocs awa amakhala osavuta kuchotsa kudzera muzosefera zotsatira.

Mapangidwe a flocs ndi ofunikira kuti achotse zowononga zosiyanasiyana m'madzi. PAC imachotsa bwino zolimba zoyimitsidwa, monga tinthu tadongo, silt, ndi organic kanthu, poziphatikiza mumagulu. Zolimba zoyimitsidwazi zimatha kuyambitsa chipwirikiti m'madzi, kupangitsa kuti aziwoneka ngati mitambo kapena yakuda. Ndi agglomerating particles mu lalikulu flocs, PAC facilitates awo kuchotsa pa sedimentation ndi kusefera njira, chifukwa mu bwino madzi.

Kuphatikiza apo, PAC imathandizira kuchotsa zinthu zomwe zasungunuka komanso zoyambitsa mitundu m'madzi. Zinthu zomwe zasungunuka, monga humic ndi fulvic acid, zimatha kupereka kukoma kosasangalatsa ndi fungo losasangalatsa kumadzi ndipo zimatha kuchitapo kanthu ndi mankhwala opha tizilombo kuti apange mankhwala ophera tizilombo toyambitsa matenda. PAC imathandiza kuti ma coagulate azitha kukhazikika komanso kukopa zinthu za organiczi pamwamba pa magulu opangidwa, potero amachepetsa kuchuluka kwawo m'madzi oyeretsedwa.

Kuphatikiza pa zinthu zachilengedwe, PAC imathanso kuchotsa zowononga zosiyanasiyana m'madzi. Zowonongekazi zingaphatikizepo zitsulo zolemera, monga arsenic, lead, ndi chromium, komanso anions ena monga phosphate ndi fluoride. PAC imagwira ntchito popanga ma insoluble metal hydroxide precipitates kapena potengera ayoni achitsulo pamwamba pake, potero amachepetsa kuchuluka kwawo m'madzi oyeretsedwa mpaka kufika pamiyezo yogwirizana ndi malamulo.

Kuphatikiza apo, PAC imawonetsa zabwino kuposa ma coagulant ena omwe amagwiritsidwa ntchito kwambiri pochiza madzi, monga aluminium sulfate (alum). Mosiyana ndi alum, PAC sisintha kwambiri pH ya madzi panthawi ya coagulation, zomwe zimathandiza kuchepetsa kufunika kwa mankhwala osintha pH ndikuchepetsa mtengo wonse wa mankhwala. Kuphatikiza apo, PAC imapanga zotayira zochepa poyerekeza ndi alum, zomwe zimapangitsa kutsika kwamitengo yotayika komanso kuwononga chilengedwe.

Ponseponse, Poly Aluminium Chloride (PAC) ndi coagulant yothandiza kwambiri yomwe imagwira ntchito yofunika kwambiri pochotsa zowononga zosiyanasiyana m'madzi. Kutha kwake kulimbikitsa coagulation, flocculation, sedimentation, ndi adsorption njira zimapangitsa kuti ikhale gawo lofunikira pamakina opangira madzi padziko lonse lapansi. Pothandizira kuchotsedwa kwa zinthu zolimba zoyimitsidwa, zinthu zosungunuka, zinthu zomwe zimayambitsa mitundu, ndi zowonongeka, PAC imathandiza kupanga madzi akumwa oyera, omveka bwino komanso otetezeka omwe amakwaniritsa malamulo. Kutsika mtengo kwake, kugwiritsa ntchito mosavuta, komanso kuchepa kochepa pa pH yamadzi kumapangitsa kukhala chisankho chokondedwa kwa malo opangira madzi kufunafuna njira zodalirika komanso zokhazikika zoyeretsera madzi.
