Mulingo woyenera kwambiri wa pH wa polyaluminium chloride mumadzi otayira a mapepala
Liti Polyaluminium Chloride amagwiritsidwa ntchito pochiza zimbudzi zopanga mapepala, mtundu wabwino kwambiri wa pH umakhudzidwa ndi zinthu zambiri. Maphunziro osiyanasiyana ndi magwiridwe antchito amapereka milingo yosiyana pang'ono, nthawi zambiri pakati pa 6 ndi 9. Zotsatirazi ndizochitika zenizeni mu data yosiyana:
Mchere ndi chimodzi mwazizindikiro zazikulu za polyferric sulfate (PFS), ndipo kutsika kwake komanso kutsika kumakhudza mwachindunji magwiridwe antchito a flocculation. Chikoka chapadera limagwirira ndi zochitika ntchito ndi monga
Chikoka chachindunji cha salinity pakuchita bwino kwa flocculation
Kufunika kwa zinthu za alumina mu polyaluminium kloride
M'munda wa mankhwala a zimbudzi ndi Kuyeretsa Madzi, polyaluminium chloride ndi yogwiritsidwa ntchito kwambiri komanso yothandiza kwambiri. Pakati pa zizindikiro zosiyanasiyana zowunika momwe polyaluminium chloride imagwirira ntchito, zomwe zili mu aluminium oxide mosakayikira ndi chimodzi mwazinthu zofunika kwambiri. Imakhudza kwambiri mphamvu, kuchuluka kwa ntchito, komanso kutsika mtengo kwa polyaluminium chloride.
Njira yodziwira za Polyaluminium Chloride
Monga coagulant yofunika kwambiri pamankhwala amadzi, kuzindikira kwa polyaluminium chloride (Pac) khalidwe liyenera kuchitidwa mozungulira zizindikiro zazikulu, kuphatikizapo aluminiyamu, mchere, pH mtengo ndi madzi osasungunuka, ndi zina zotero.
Nayitrojeni Wokwanira Woposa Mulingo Ndi Mphamvu Zake pa Njira Zoyeretsera Zonyansa
Kuchuluka kwa nayitrogeni wokwanira pamadzi ochotsera zinyalala kumawonekera makamaka pakugwirira ntchito bwino, zochitika zazing'onoting'ono, komanso kusasunthika kwa utsi, monga tafotokozera mwatsatanetsatane pakuwunika ndi malingaliro awa:
Ubwino ndi kuipa kwa njira yokonzekera aluminium chloride
Chitsulo zotayidwa njira: liwiro anachita ndi mofulumira, ndipo kuchuluka kwa polyaluminium kolorayidi akhoza analandira mu nthawi yochepa. Komanso, zitsulo za aluminiyamu zimapezeka kwambiri, zomwe zimapereka chitsimikizo cha kupanga kwakukulu.
Kusiyana pakati pa polyaluminium chloride ndi polyaluminium ferric chloride
Aluminiyamu kolorayidi (PAC) ndi polyaluminium ferric chloride (PAFC) ndi awiri omwe amagwiritsidwa ntchito kwambiri polima polima flocculants, kusiyana kwakukulu ndi motere:
Ntchito minda ya white polyaluminium kolorayidi
White polyaluminium chloride (yomwe imadziwikanso kuti kupukuta polyaluminium chloride) imagwiritsidwa ntchito kwambiri m'magawo ambiri chifukwa cha kuyera kwake komanso kutsika kwake kosadetsedwa. Zotsatirazi ndi zochitika zake zogwiritsira ntchito komanso ubwino wake:
Kusiyana pakati pa polyferric sulphate ndi ferrous sulphate
Kusiyanitsa kwakukulu pakati pa ferrous sulfate ndi polymeric ferric sulfate kumawonetsedwa ndi mankhwala, zotsatira za mankhwala, zochitika zogwiritsira ntchito komanso kusinthasintha kwa chilengedwe, motere:
