Abstract

Yeast production wastewater is one of the complex wastewater types, characterized by high organic content and color. This research on the application of non-thermal plasma in laboratory scale yeast production has demonstrated the superiority of this technology in terms of efficiency, treatment time and non- selectivity for pollutants. The wastewater treatment model is optimized in 3 minutes with a DC voltage of 100 V and a pH around 8.4, resulting in COD removal efficiency of over 75%, while color and TSS removal of 93%. The results of this study are the basis for practical application of wastewater at AB Mauri Vietnam after biological treatment stage (anaerobic, anoxic and aerobic) with a COD of greater than 5,000 mg/l and color over 26,000 Pt-Co.
