This paper studied a new method to improve the microbial activity of the activated sludge for wastewater treatment. Concentrated sludge was sonicated in an extra chamber for short period and then returned to the activated sludge system. The results showed that the bio-activity of the activated sludge, expressed as oxygen utilization rate (OUR), could be… CONTINUE READING
