Ngwọta mmiri bụ akụkụ dị mkpa nke nchebe gburugburu ebe obibi na ahụike ọha na eze, na nzube ya bụ iji hụ na mmiri dị mma ma gboo mkpa nke ngwa dị iche iche. N'ime ọtụtụ ụzọ ọgwụgwọ mmiri,polyaluminom chlorideA na-ahọrọ (PAC) maka akụrụngwa pụrụ iche yana mmetụta coagulation nke ọma.
Mmetụta coagulation nke ọma: PAC nwere arụmọrụ coagulation dị mma ma nwee ike wepu ihe adịghị ọcha dị ka ihe siri ike kwụsịtụrụ, colloid na ihe ndị na-adịghị edozi ahụ na mmiri ma melite ogo mmiri.
Usoro nke polyaluminium chloride (PAC) dị ka coagulant na-agụnye mkpakọ nke okpukpu abụọ eletrik, nkwụsị ụgwọ na ọnyà net. Mkpakọ nke oyi akwa eletrik okpukpu abụọ pụtara na mgbe agbakwunyere PAC na mmiri, aluminom ions na ion chloride na-etolite oyi akwa adsorption n'elu akụkụ nke colloidal, si otú ahụ na-eme ka okpukpu abụọ nke ọkụ eletrik dị n'elu akụkụ nke colloidal, na-eme ka ha ghara ịda mbà na condens; mgbasa ozi mgbasa ozi bụ The cations na ụmụ irighiri ihe PAC na-adọta ibe ha na ebubo na-adịghị mma n'elu akụkụ nke colloidal, na-eme usoro "akwa" iji jikọta ọtụtụ ihe colloidal; Mmetụta netting bụ site na mgbasa ozi na nchikota mmetụta nke ụmụ irighiri ihe PAC na colloidal particles, nke na-eme ka ụgbụ colloidal.

A na-eji ọgwụgwọ mmiri polyaluminum chloride
E jiri ya tụnyere inorganic flocculants, ọ na-emeziwanye mmetụta decolorization nke agba. Usoro ya na-eme bụ na PAC nwere ike ịkwalite ụmụ irighiri ihe ndị na-esiji esiji ka ha mepụta flocs dị mma site na mkpakọ ma ọ bụ nkwụsị nke oyi akwa abụọ eletrik.
Mgbe ejiri PAM jikọtara ya na PAC, ụmụ irighiri ihe ndi ozo nke anionic polymer nwere ike iji nchikota nke agbụ molekụla ogologo ha wee mepụta flocs toro ogologo site na nkwado nke onye na-emebi emebi. Usoro a na-enyere aka melite mmetụta nhazi ma mee ka ion metal dị arọ dị mfe iwepụ. Na mgbakwunye, ọnụ ọgụgụ buru ibu nke otu amide dị n'ime ụdọ akụkụ nke ụmụ irighiri ihe polyacrylamide anionic nwere ike ime njikọ ion na -SON n'ime ụmụ irighiri ihe. Nhazi nke njikọ kemịkalụ a na-ebelata solubility nke organic flocculant na mmiri, si otú ahụ na-akwalite nhazi ngwa ngwa na mmiri ozuzo nke flocs. Usoro njikọ dị omimi a na-eme ka o sie ike maka ion metal dị arọ ịgbanahụ, na-eme ka arụmọrụ na mmetụta nke ọgwụgwọ dịkwuo mma.
N'ihe gbasara mwepụ nke phosphorus, a pụghị ileghara ịdị irè nke polyaluminum chloride anya. Mgbe etinyere ya na mmiri mkpofu nwere phosphorus, ọ nwere ike ịze mmiri iji mepụta ion metal metal trivalent. Ion a na-ejikọta na phosphates soluble n'ime mmiri mkpofu, na-eme ka nke ikpeazụ ghọọ phosphate na-enweghị ike ime. Usoro ntụgharị a na-ewepụ ion phosphate nke ọma na mmiri mkpofu ma na-ebelata mmetụta ọjọọ nke phosphorus na mmiri.
Na mgbakwunye na mmeghachi omume ozugbo na phosphate, mmetụta coagulation nke polyaluminum chloride na-arụkwa ọrụ dị mkpa na usoro mwepụ nke phosphorus. Ọ nwere ike nweta adsorption na ijikọ site na ịpịkọta oyi akwa ụgwọ n'elu ion phosphate.
