30% Polyaluminum Chloride (PAC) yochizira madzi - Kugwira ntchito bwino kwa mafakitale ambiri
Ndi kusintha kosalekeza kwa miyezo yosamalira madzi m'mafakitale komanso yosamalira madzi otayidwa m'matauni, kufunikira kwa msika wa zinthu zogwira ntchito bwino komanso zokhazikika za polyaluminum chloride (PAC) kukupitilira kukula.

Kodi Ferric Sulfate Ndi Yofanana Ndi Polymeric Ferric Sulfate?
Kodi polyaluminum chloride ndi acidic kapena alkaline?
Polyaluminum Chloride (PAC) ndi polima yopanda chilengedwe yokhala ndi kapangidwe ka mankhwala a poly-nuclear hydroxyl complexes (njira yodziwika bwino: [Al₂(OH)ₙCl₆₋ₙ]ₘ). Akasungunuka m'madzi, ma ayoni a aluminiyamu (Al³⁺) amakumana ndi ma hydrolysis reaction, kutulutsa ma ayoni a hydrogen (H⁺) omwe amapanga yankho la acidic ndi pH yokhazikika pakati pa 2.0–4.5. Khalidwe ili limapatsa PAC zabwino zotsatirazi.
Kusiyana Pakati pa Polyaluminum Ferric Chloride ndi Polyaluminum Chloride
Zinthu zomwe zingagwiritsidwe ntchito nthawi zonse mutatha kukhudzidwa ndi chinyezi
Ngati polyferric sulfate yolimba imangotupa chifukwa cha chinyezi, koma palibe oxidation kapena kusintha kwa mtundu (monga chikasu kapena kufiira), ingagwiritsidwebe ntchito nthawi zonse mutaiphwanya. Mukamaigwiritsa ntchito, ndikofunikira kulimbitsa kusakaniza kuti muchepetse kusungunuka ndikuwonjezera kuchuluka kwa yankho kuti muwonetsetse kuti flocculation ikugwira ntchito bwino.
Kodi ndi chiyani chomwe chingagwiritsidwe ntchito m'malo mwa polyaluminum chloride pochiza zimbudzi?
Pochiza zimbudzi, polyaluminum chloride (PAC) imagwiritsidwa ntchito kwambiri, koma njira zina zotsatirazi zitha kuganiziridwa pazochitika zinazake (monga kuchepetsa zotsalira za aluminiyamu, kusintha kuti madzi azitentha bwino kapena kukonza mtengo wake):
Kugwiritsa ntchito polyferric sulfate mu ulimi wa nsomba
Polyferric sulfate (PFS) imagwiritsidwa ntchito ngati njira yabwino yochepetsera madzi komanso yochepetsera zinyalala mu ulimi wa nsomba. Ikhoza kusintha kwambiri malo osungira nsomba kudzera mu kuyandama, mvula, kusungunuka kwa okosijeni, kuwola ndi kuwonjezera michere. Ntchito zake ndi izi:
