Usoro ngwaahịa

Nkà na ụzụ EDI bụ usoro ntọhapụ ọhụrụ nke na-ejikọta electrodialysis na mgbanwe ion.Usoro a na-eji ohere dị ike nke ma electrodialysis na mgbanwe ion na-akwụ ụgwọ maka adịghị ike ha.Ọ na-eji mgbanwe ion na-atụgharị miri emi iji merie nsogbu nke desalination na-ezughị ezu nke polarization electrodialysis kpatara.Ọ na-ejikwa electrodialysis polarization iji mepụta H+ na OH-ions maka mmeghari resin na-akpaghị aka, nke na-emeri mweghachi nke kemịkalụ mweghachi mgbe resin dara.Ya mere, teknụzụ EDI bụ usoro mkpochapụ zuru oke.

N'oge usoro mkpochapụ EDI, ion dị na mmiri na-agbanwe ion hydrogen ma ọ bụ ion hydroxide na resin mgbanwe ion, mgbe ahụ, ion ndị a na-akwaga n'ime mmiri a gbanyere mkpọrọgwụ.Mmeghachi omume mgbanwe ion a na-eme n'ime ụlọ mmiri na-agbaze nke otu.N'ime ụlọ mmiri na-agbaze, ion hydroxide na anion mgbanwe resin mgbanwe na anions na mmiri, na hydrogen ion na cation mgbanwe resin mgbanwe na cations na mmiri.Ion ndị ahụ gbanwere na-akwaga n'elu bọọlụ resin n'okpuru ọrụ nke ọkụ eletrik DC wee banye n'ọnụ ụlọ mmiri gbadoro anya site na mgbanwe ion.

Anion na-adịghị mma na-adọrọ mmasị na anode wee banye n'ọnụ ụlọ mmiri dị n'akụkụ site na akpụkpọ anụ anion, ebe akpụkpọ anụ dị n'akụkụ na-egbochi ha ịgafe ma na-egbochi ion ndị a n'ime mmiri ahụ.A na-adọta cations ndị a na-akwụ ụgwọ nke ọma na cathode wee banye n'ọnụ ụlọ mmiri dị n'akụkụ site na akpụkpọ ahụ cation, ebe akpụkpọ anụ anion dị n'akụkụ na-egbochi ha ịgafe ma na-egbochi ion ndị a na mmiri a na-etinye.

N'ime mmiri a na-etinye uche, ions si n'akụkụ abụọ ahụ na-echekwa nnọpụiche eletriki.Ka ọ dị ugbu a, mgbanwe nke ugbu a na ion dị nhata, na nke ugbu a nwere akụkụ abụọ.Otu akụkụ na-abịa site na mbugharị nke ions wepụrụ, akụkụ nke ọzọ na-abịa site na ntugharị nke ion mmiri nke na-abanye n'ime H + na OH- ions.Mgbe mmiri na-agafe na mmiri na-esi na mmiri na-ekpo ọkụ na ebe a na-etinye uche na mmiri, ion ndị ahụ ji nwayọọ nwayọọ na-abanye n'ime ụlọ mmiri dị n'akụkụ ma na-ebufe ya na EDI unit na mmiri na-ekpo ọkụ.

N'okpuru elu voltaji gradient, mmiri na-electrized na-emepụta a nnukwu ego nke H + na OH-, na ndị a na saịtị na-emepụta H + na OH- nọgidere na-na-na-na-na-na-na-na-na-na-na-na-na-na-na-na-na-resin na mgbanwe resin.Ya mere, resin mgbanwe ion na ngalaba EDI anaghị achọ mmeghari kemịkalụ.Nke a bụ usoro mkpochapụ EDI.
