Electrocoagulation - Electroflotation
Electrocoagulation, a gaskiya, shine electroflotation, kamar yadda tsarin coagulation yana faruwa a lokaci guda tare da iyo. Saboda haka, ana iya kiransa tare da "electrocoagulation-electroflotation."
Wannan hanyar ta dogara ne akan aikace-aikacen wutar lantarki na waje, wanda ke haifar da cations masu narkewa a cikin anode. Waɗannan cations suna da tasirin coagulating akan gurɓataccen ƙwayar cuta. A lokaci guda, ana samar da iskar hydrogen gas mai yawa a cikin cathode a ƙarƙashin rinjayar ƙarfin lantarki, wanda ke taimaka wa abubuwan da ke gudana su tashi sama. Ta wannan hanyar, electrocoagulation yana kaiwa ga rabuwa da gurɓataccen ruwa da tsarkake ruwa ta hanyar coagulation na anode da cathode flotation.
Yin amfani da ƙarfe azaman anode mai narkewa (yawanci aluminum ko ƙarfe), ions na Al3+ ko Fe3+ da aka samar yayin electrolysis suna aiki azaman coagulant na lantarki. Wadannan coagulant suna aiki ta hanyar damfara Layer biyu na colloidal, suna lalata shi, da haɗawa da ɗaukar ƙwayoyin colloidal ta:
Al -3e→ Al3+ ko Fe -3e → Fe3+
Al3+ + 3H2O → Al(OH)3 + 3H+ ko 4Fe2+ + O2 + 2H2O → 4Fe3+ + 4OH-
A daya hannun, da kafa electroactive coagulant M (OH) n ana magana da shi azaman mai narkewa polymeric hydroxo complexes kuma yana aiki azaman flocculant don saurin daidaita abubuwan dakatarwar colloidal (kyakkyawan ɗigon mai da ƙazanta na inji) a cikin ruwan sharar gida yayin haɗawa da haɗa su don samar da su. mafi girma aggregates, bugun sama da rabuwa tsari. A daya hannun, colloid suna matsawa a ƙarƙashin rinjayar electrolytes kamar aluminum ko baƙin ƙarfe gishiri, haifar da coagulation ta hanyar Coulombic sakamako ko adsorption na coagulant.
Ko da yake aikin electrochemical (tsawon rayuwa) na masu samar da wutar lantarki na ƴan mintuna kaɗan ne kawai, suna da matukar tasiri ga yuwuwar Layer biyu, don haka suna yin tasirin coagulation mai ƙarfi akan ƙwayoyin colloidal ko ɓangarorin da aka dakatar. A sakamakon haka, ƙarfin tallan su da ayyukansu sun fi hanyoyin sinadarai da suka haɗa da ƙari na reagents na gishiri na aluminum, kuma suna buƙatar ƙananan kuɗi kuma suna da ƙananan farashi.
