Kodi Poly Aluminium Chloride imachotsa bwanji zinthu zodetsa m'madzi?

Poly Aluminiyamu Chloride(PAC) ndi mankhwala omwe amagwiritsidwa ntchito kwambiri pochiza madzi ndi madzi otayidwa chifukwa cha mphamvu yake yochotsa zinthu zodetsa. Kagwiridwe kake ka ntchito kamakhala ndi njira zingapo zofunika zomwe zimathandiza kuti madzi ayeretsedwe.

Choyamba, PAC imagwira ntchito ngati cholumikizira madzi m'njira zotsukira madzi. Kutsekeka kwa madzi ndi njira yosokoneza tinthu ta colloidal ndi suspensions m'madzi, zomwe zimapangitsa kuti tigwirizane ndikupanga tinthu tating'onoting'ono totchedwa flocs. PAC imakwaniritsa izi mwa kuchepetsa mphamvu zoyipa pamwamba pa tinthu ta colloidal, zomwe zimawalola kuti agwirizane ndikupanga flocs kudzera mu njira yotchedwa charge neutralization. Kenako flocs izi zimakhala zosavuta kuchotsa kudzera mu njira zotsatizana zosefera.

Kupangidwa kwa ma floc ndikofunikira kwambiri pochotsa zinthu zosiyanasiyana zodetsa m'madzi. PAC imachotsa bwino zinthu zolimba zomwe zapachikidwa, monga tinthu ta dongo, matope, ndi zinthu zachilengedwe, poziyika mu ma floc. Zinthu zolimba zimenezi zimatha kuyambitsa matope m'madzi, zomwe zimapangitsa kuti azioneka ngati mitambo kapena mdima. Mwa kusonkhanitsa tinthu timeneti kukhala ma floc akuluakulu, PAC imathandiza kuti zichotsedwe panthawi yothira madzi ndi kusefa, zomwe zimapangitsa kuti madzi azikhala oyera.

Kuphatikiza apo, PAC imathandiza kuchotsa zinthu zachilengedwe zosungunuka ndi zinthu zomwe zimayambitsa utoto m'madzi. Zinthu zachilengedwe zosungunuka, monga humic ndi fulvic acids, zimatha kupangitsa madzi kukhala ndi kukoma kosasangalatsa komanso fungo loipa ndipo zimatha kuchitapo kanthu ndi mankhwala ophera tizilombo toyambitsa matenda kuti apange zinthu zina zowononga tizilombo toyambitsa matenda. PAC imathandiza kutseka ndi kuyamwa mankhwala achilengedwe awa pamwamba pa ma flocs opangidwa, motero amachepetsa kuchuluka kwawo m'madzi okonzedwa.

Kuwonjezera pa zinthu zachilengedwe, PAC imathanso kuchotsa zinthu zosiyanasiyana zosapangidwa kuchokera m'madzi. Zinthu zimenezi zingaphatikizepo zitsulo zolemera, monga arsenic, lead, ndi chromium, komanso ma anion ena monga phosphate ndi fluoride. PAC imagwira ntchito popanga zinthu zosasungunuka zachitsulo hydroxide kapena kuyamwa ma ayoni achitsulo pamwamba pake, motero imachepetsa kuchuluka kwawo m'madzi okonzedwawo kufika pamlingo womwe ukugwirizana ndi miyezo yoyenera.

Kuphatikiza apo, PAC ili ndi ubwino kuposa ma coagulants ena omwe amagwiritsidwa ntchito kwambiri pochiza madzi, monga aluminium sulfate (alum). Mosiyana ndi alum, PAC sisintha kwambiri pH ya madzi panthawi yothira madzi, zomwe zimathandiza kuchepetsa kufunikira kwa mankhwala osinthira pH ndikuchepetsa mtengo wonse wochizira. Kuphatikiza apo, PAC imapanga matope ochepa poyerekeza ndi alum, zomwe zimapangitsa kuti ndalama zotayira zichepe komanso kuwonongeka kwa chilengedwe.

Ponseponse, Poly Aluminium Chloride (PAC) ndi coagulant yogwira ntchito kwambiri yomwe imagwira ntchito yofunika kwambiri pochotsa zinthu zosiyanasiyana zodetsa m'madzi. Kuthekera kwake kulimbikitsa kugawanika, kuyandama, kusungunuka, ndi njira zothira madzi kumapangitsa kuti ikhale gawo lofunikira kwambiri m'machitidwe ochizira madzi padziko lonse lapansi. Mwa kuthandizira kuchotsa zinthu zolimba zomwe zapachikidwa, zinthu zachilengedwe zosungunuka, mankhwala oyambitsa mitundu, ndi zinthu zopanda chilengedwe, PAC imathandiza kupanga madzi oyera, oyera, komanso otetezeka omwe amakwaniritsa miyezo yovomerezeka. Kugwiritsa ntchito kwake mopanda mtengo, kosavuta kugwiritsa ntchito, komanso kuchepa kwa pH ya madzi kumapangitsa kuti ikhale chisankho chabwino kwambiri cha mafakitale ochizira madzi omwe akufuna njira zodalirika komanso zokhazikika zoyeretsera madzi.
