Characterization of South African Brewery Wastewater: Oxidation-Reduction Potential Variation

Conventional wastewater treatment processes are challenged by the need to effectively reduce pollutant loads before disposal or reuse, as composition and concentration of contaminants in brewery change with time. This results variation oxidation-reduction potential (ORP) affluent. Hence, current study is aimed at application ORP a real-time tool monitor quality. Other physicochemical parameters local South Africa investigated included temperature (T), pH, conductivity, turbidity, total chemical oxygen demand (TCOD), soluble (SCOD), particulate (PCOD), solids, orthophosphate, ammoniacal nitrogen, Kjeldahl nitrogen (TKN), (TN), nitrate, nitrite nitrogen. It was found that decreased (135 ?305 mV) an increase alkalinity (pH 4.4 12.2) linear regression coefficient fit (R2 = 0.9994). The facilitated nutrient constituent degradability which improved water Furthermore, high organic content measured COD (3447–11,813 mg/L). suggests remediation reuse will require robust integrated process.
