Treatment of wastewaters from food Aromsa and ingredients production by electrocoagulation (EC) treatment aided by mucilage of Opuntia ficus-indica

Mehmet KOBYA

The electrocoagulation (EC) treatment process was aided by the cladode mucilage of Opuntia ficus-indica (OFI) to improve chemical oxygen demand (COD) removal efficiency () of wastewater from a plant producing flavoring and food additives. The studied variables included initial pH, current density, types of electrodes (Fe and Al), mucilage concentration, and charge loading. The EC treatment using Al electrodes, assisted by an optimum concentration of 200 mg L-1 OFI mucilage, a current density of 60 A/m2, and an initial pH equal to 3, improved the COD removal efficiency (69.77) at an EC treatmen ...Более
