Kugawa mitundu ya PAC ndi milingo yofanana
Kusiyana kwa mitundu ya PAC kumasonyeza mwachindunji mulingo wake wa chiyero ndi zigawo zake zazikulu, zomwe zimagawidwa m'magawo anayi:

Pochiza zimbudzi, kugwiritsa ntchito pamodzi kwa PAC (polyaluminum chloride) ndi PAM (polyacrylamide) ndi njira yodziwika bwino yogwiritsira ntchito. Chifukwa chachikulu chili mu njira yothandizirana komanso mphamvu yogwirizana ya ziwirizi, ndipo zotsatira zabwino kwambiri zochizira sizingapezeke pozigwiritsa ntchito padera. Izi ndi kusanthula mfundo ndi mfundo za zifukwa zazikulu:

Malinga ndi kusanthula kwathunthu kwa malamulo omwe alipo komanso zinthu zomwe zilipo, polyaluminum chloride (PAC) si chinthu choopsa mwalamulo, koma chifukwa cha zinthu zake zomwe zimagwiritsidwa ntchito, kugwiritsa ntchito ndi kusungira kuyenera kutsatira malamulo achitetezo. Kusanthula kwapadera ndi motere:

1. Kuwunika zizindikiro zazikulu za khalidwe

1. Kuchuluka kwa aluminiyamu (Al₂O₃)

● Giredi ya mafakitale: ≥28% (chimango cha mbale/mtundu wa spray), giredi ya madzi akumwa: ≥30%;

● Dziwani: Kuchuluka kwa madzi (30%) kungakhale kosathandiza m'madzi okhala ndi asidi/madzi opanda matope ambiri ndipo kuyenera kufanana ndi ubwino wa madzi.

Polyaluminum chloride (PAC) youma ndi roller-dry, yomwe ndi flocculant yothandiza kwambiri poyeretsa madzi, imagwiritsidwa ntchito kwambiri poyeretsa madzi komanso posamalira madzi otayira. Monga mtundu wolimba wa polyaluminum chloride (PAC), imapangidwa pogwiritsa ntchito njira yowumitsa ng'oma, zomwe zimapereka zabwino monga kusungira mosavuta komanso kugwiritsa ntchito bwino kwambiri. Pansipa ndifotokoza mfundo zazikulu:

Malinga ndi "PAC ya madzi akumwa" (GB15892-2020), zizindikiro zazikulu ndi izi:

Kuchuluka kwa Alumina (Al₂O₃): madzi> kapena ofanana ndi 10%, olimba> kapena ofanana ndi 29%, kuti zitsimikizire kuti flocculation ikuyenda bwino.

Kukhazikika kwa zoletsa zachilengedwe kwapangitsa kuti mphamvu zopanga zazing'ono ndi zapakati zichoke. Mwachitsanzo, m'dera la PAC lopanga ku Gongyi, Henan, mtengo wa Q1 unakwera ndi 10% pakanthawi kochepa chifukwa cha zoletsa zachilengedwe mu 2025. Pakapita nthawi, kuwunika zachilengedwe kwachotsa mphamvu zopanga zochepa (monga zinthu zopanda kuyera kotsika zopangidwa pogwiritsa ntchito njira ya drum), zomwe zapangitsa kuti makampani ambiri aziganizira kwambiri za malonda komanso kuti makampani otsogola azitha kuchita bwino kwambiri.

Madzi akumwa a polyaluminum chloride ndi chosakaniza cha polymer chosapangidwa mwachilengedwe chomwe chimapangidwira kuyeretsa madzi akumwa. Fomula yake ya mankhwala ndi [Al₂(OH)ₙCl₆−n]m[Al₂​(OH)ₙCl₆−n​]m​. Chogulitsachi chikugwirizana ndi "Hygienic Standard for Drinking Water" yaku China yokhudza kuchuluka kwa zitsulo zolemera (arsenic ≤0.0005%, lead ≤0.001%) ndi kuchuluka kwa mchere (40%-60%). Poyerekeza ndi zinthu zamakampani, zikuwonetsa zabwino zake:
