We reported (Biochem. Eng. J.the performance of a high-pressure jet device (HPJD) that destroys bacterial cells and releases dissolved organic matter (DOM). HPJD treatment attracts attention as a method to decrease activated sludge. Specifically, they investigate the effects of pressure, repeated batch treatment, and injection ratio on the disintegration of Escherichia coli and Bacillus subtillis cells. In addition, tryptophan- and tryrosine – that are amino acids were released from E. coli and B. subtilis cells.

This study contributes to the use of more effective activated sludge at water purification plant.
