Electrocoagulation-Electroflotation
N'eziokwu, electrocoagulation bụ electroflotation, ebe usoro coagulation na-eme n'otu oge na flotation. Ya mere, a pụrụ ịkpọ ya "electrocoagulation-electroflotation."
Usoro a dabere na ojiji nke voltaji eletrik mpụga, nke na-emepụta cations na-agbaze na anode. Cations ndị a nwere mmetụta njikọta na ihe ndị na-emerụ emerụ na colloidal. N'otu oge ahụ, a na-emepụta nnukwu gas hydrogen na katode n'okpuru mmetụta nke voltaji ahụ, nke na-enyere ihe ndị na-agbaze aka ebili n'elu. N'ụzọ dị otu a, electrocoagulation na-eme ka nkewa nke ihe ndị na-emerụ emerụ na ịsacha mmiri site na anode coagulation na cathode flotation.
Site n'iji ígwè dị ka anode na-agbaze agbaze (nke a na-akpọkarị aluminom ma ọ bụ ígwè), ion Al3+ ma ọ bụ Fe3+ nke a na-emepụta n'oge electrolysis na-eje ozi dị ka coagulants electroactive. Coagulants ndị a na-arụ ọrụ site na ịpịkọta oyi akwa abụọ nke colloidal, imebi ya, na ijikọ na ijide ihe ndị mejupụtara colloidal site na:
Al -3e → Al3+ ma ọ bụ Fe -3e → Fe3+
Al3+ + 3H2O → Al(OH)3 + 3H+ ma ọ bụ 4Fe2+ + O2 + 2H2O → 4Fe3+ + 4OH-
N'otu aka, a na-akpọ M(OH)n nke e guzobere dị ka ihe mgbagwoju anya mmiri polymeric nke na-agbaze ma na-arụ ọrụ dị ka ihe na-agbaze iji mee ka ihe mgbochi mmiri colloidal (mmiri mmanụ dị mma na ihe ndị na-adịghị ọcha) dị n'ime mmiri mkpofu ngwa ngwa ma dị irè ebe ọ na-ejikọ ma na-ejikọ ha iji mepụta mkpokọta buru ibu, na-eme ka usoro nkewa ahụ dị ngwa. N'aka nke ọzọ, a na-akpọkọ colloids n'okpuru mmetụta nke electrolytes dị ka aluminom ma ọ bụ nnu ígwè, na-eduga na coagulation site na mmetụta Coulombic ma ọ bụ adsorption nke coagulants.
Ọ bụ ezie na ọrụ electrochemical (ndụ) nke electroactive coagulants dị naanị nkeji ole na ole, ha na-emetụta ike okpukpu abụọ nke ukwuu, si otú a na-enwe mmetụta siri ike nke coagulation na mkpụrụ colloidal ma ọ bụ mkpụrụ ndị a kwụsịrị. N'ihi ya, ikike na ọrụ ha dị elu karịa usoro kemịkalụ gụnyere itinye ihe ndị na-eme ka aluminom nnu reagents dịkwuo elu, ha chọrọ obere ego ma nwee ọnụ ahịa dị ala. Ọnọdụ gburugburu ebe obibi, okpomọkụ mmiri, ma ọ bụ ihe ndị na-adịghị mma na-emetụta electrocoagulation, ọ naghịkwa enweta mmeghachi omume ndị ọzọ na nnu aluminom na mmiri hydroxides. Ya mere, o nwere oke pH sara mbara maka ịgwọ mmiri mkpofu.
Ọzọkwa, mwepụta nke obere afụfụ n'elu cathode na-eme ka nkukota na nkewa nke colloids dịkwuo ngwa ngwa. Elektro-oxidation kpọmkwem na elu anode na electro-oxidation na-apụtaghị ìhè nke Cl- n'ime chlorine na-arụ ọrụ nwere ikike oxidation siri ike na ihe ndị dị ndụ na-agbaze na ihe ndị na-adịghị arụ ọrụ na mmiri. Hydrogen ọhụrụ sitere na cathode na oxygen sitere na anode nwere ikike redox siri ike.
N'ihi ya, usoro kemịkalụ ndị na-eme n'ime ihe nrụpụta electrochemical dị oke mgbagwoju anya. N'ime ihe nrụpụta electrocoagulation, usoro electroflotation, na electrooxidation niile na-eme n'otu oge, na-agbanwe ma na-ewepụ ma colloids agbazere agbaze na ihe ndị na-emerụ emerụ n'ime mmiri site na coagulation, flotation, na oxidation.
