Sažetak
The paper presents a new approach which combines electrochemical methods and ozonation to wastewater treatment from potato processing in potato chips production. This wastewater is characterized by high values of total suspended solids (1517 mg dm-3), chemical oxygen demand (2240 mg dm-3) and biochemical oxygen demand (1780 mg dm-3) that exceed the limit values for discharges into the environment by 43.18 and 71 times, respectively. For the purpose of optimisation of this process, the paper investigated the impact of different electrode types (stainless steel, iron, aluminium), contact time (5-30 minutes) and amperage (30-100 A) on the degree of removal of these three parameters. Although the aluminium electrode set proved the most effective for the removal of these indicators, significantly better results were obtained by a combination of all three electrode types with simultaneous ozonation. After 10 minutes of electrocoagulation / electrooxidation with stainless steel electrodes, 5 minutes of electrocoagulation / ozonation with iron electrodes, 15 minutes of electrocoagulation / ozonation with aluminium electrodes and 15 minutes of ozonation, 100% colour, turbidity and TSS, 94.5% COD and 98. 9% BOD5 were removed, and all measured indicators met the requirements for discharges into the environment.
