Sažetak
Subject matter of the invention is the procedure and plant for industrial wastewater and/or drinking water treatment by means of electrochemical methods and advanced oxidation processes. The preparatory phase of gravitational sedimentation is followed by main treatment consisting of electrocoagulation, electrooxidation and electroflotation through action of metal electrode sets made of inox, steel and aluminium respectively, with parallel disinfection/oxidation with ozone, UV irradiation and ultrasonic treatment, as well as recirculation in the electromagnetic field. At the end of the main treatment, the mixture of floccule and water is subject to coagulation/flocculation by electrochemically generated steel and aluminium floccule with slow infusion of ozone. The next phase is separation of sediment from clean water which is discharged through sand and activated charcoal filters for the purpose of removal of light floating floccule in the collection tank. If required, the water is subject to oxidation with simultaneous action of UV irradiation and ozone for the purpose of final destruction of organic matter and ammonia, and potential residues of microbiological contamination.
