Izimiso nezindlela zokwelashwa kwamanzi amdaka kwakhiqizwa ukwelashwa kwephrofayili ye-aluminium

Amanzi amdaka akhiqizwa ngu Ukwelashwa kwe-Aluminium Survece Survent ikakhulukazi i-Acid-Base Wandwitor Wall, equkethe inani elincane le-anions ayingozi njenge-ni2 +, SN2 +, kanye ne--. Indlela yokwelashwa ingukungathathi hlangothi kwe-acid-base. Amanzi angcolile ngokuvamile acidic futhi kufanele ahlukaniswe ne-alkali ukuguqula inani le-PH inani eliku-7-8,5. Ngasikhathi sinye, ngesikhathi senqubo yokungathathi hlangothi, amazabelo njenge-al3 +, ni2, i-SN2 +, ne-CR3 + yonke ifomu i-hydroxide yezulu. Amanzi angathathi hlangothi futhi anezinwele aphonswa ethangini le-coagation ngephampu, futhi i-polyamide flocculant igcwele emanzini angcolile ngephampu enkulu ukuze aqede namanzi amdaka. Ngemuva kokugxuma, amanzi amdaka angena ethangini ledimentation. Izindlela zokudonsela phansi zifaka indlela ethambekele ethambekele yePlate Sedimentation, indlela ye-Air Flotation, indlela ye-Sedimentation ye-Air, njll. Umbhali ukholelwa ukuthi indlela ye-Centrifugal Sedimentation iqinile. Ngemuva kokudonswa kwedimentation, uketshezi olucacile luchichima ethekwini eliphezulu elichichima futhi ungene echibini lokukhipha noma ukuphindisela ithangi lokugcina amanzi.

 Ngemuva kokwelashwa okungenhla, amanzi angcolile angahlangabezana nezindinganiso zokukhishwa. Uma amanzi angcolile kufanele asetshenziswe kabusha, amanzi angcolile angalashwa ngohlu lwe-coarstration bese ufaka idivaysi ye-RO ukususa ama-anions amaningi, izakhiwo kanye nezinto eziphilayo. Inani le-PH lamanzi lingase liphansi ngalesi sikhathi, futhi lingashintshwa yi-anion ne-coation ukushintshanisa insiza ukuze uhlangane namazinga okusebenzisa kabusha. I-sludge ekhiqizwe yizinkundla ikhiqizwa njalo echibini le-sludge, futhi ngemuva kokuphathwa yikhekhe lekhekhe le-plate noma i-helt dehydrator, iba yindawo yokulahla imfucumfucu yezimboni futhi ithunyelwa kwizindawo zokwelashwa kwemfucuza yezimboni futhi ithunyelwe kwizindawo zokwelashwa kwemfucuza yezimboni.
