Aeration of anaerobically treated potato-processing wastewater

Abstract The performance of an aerated lagoon, following the anaerobic lagoon-filter units, in treating unsettled potato-processing wastewater at low temperatures between 4 and 20°C has been evaluated from a laboratory scale model. COD, SS, pH and reaction rates data have been assessed. Such a combination of reactors provided a very stable and satisfactory effluent even at temperatures as low as 4°C.
