Abstract: Beer production plant wastewater causes highly polluted wastewater to emerge, which is characterized by high concentrations of organic compounds and various contaminants. Due to the complex composition of brewery wastewater, the development of efficient purification methods is crucial. The data indicate that the wastewater is highly contaminated, rendering conventional treatment methods ineffective. One of these processes is electrooxidation (EO). EO has been identified as a promising technique for the degradation of organic pollutants, utilizing an electric current without the addition of chemical reagents.
In this study, wastewater from a beer production plant was treated using the electrooxidation process under laboratory conditions. The effects of electrode type, treatment time, electrolyte concentration and applied electrical current on the treatment of these wastewaters with the EO process were investigated. The removal efficiency of chemical oxygen demand (COD) and other pollutants from wastewater was monitored by the process. The characterization of wastewater are as follows total hardness of 300 mg/L, electrical conductivity of 600 μm/cm, and COD of ~25,000 mg/L. Over 95% COD removal (effluent COD of <1000 mg/L) was achieved under optimum conditions (applied current = 5 A, EO time = 5 hour, anode type = boron-doped diamond (BDD) electrode, and amount of electrolyte = 3 g NaCl/0.8 L wastewater. The findings demonstrate that EO process is an effective method for removing organic pollutants from brewery wastewater, thereby mitigating its environmental impact.
