Abstract

The effectiveness of ultrasonication as a pre-treatment method for the psychrophilic anaerobic treatment of aquaculture effluents was assessed using a 4 1 solids digester. Ultrasonication of aquaculture wastewater was found to enhance the removal of chemical oxygen demand by anaerobic digestion by almost 10%. There was also a concurrent increase in total biogas production from 0.29 1 day-1 to 0.45 1 day-1 with a corresponding 10% increase in methane concentration. Furthermore, there was an increase of 60% in effluent total ammonia nitrogen concentration as a result of sonication in comparison with a 45% increase for untreated digester waste.
