METHOD FOR DESTRUCTING CELLULAR STRUCTURES OF SUSPENSIONS OF MICROORGANISMS BY ULTRASOUND, ESPECIALLY SLUDES FROM BIOLOGICAL WASTEWATER PLANTS

摘要

A process is disclosed for destroying the cellular structure of microorganisms by exposing suspensions of microorganisms to ultra-sonic radiation. These suspensions of microorganisms are in particular sludges from biological sewage clarification plants. A volume and mass reduction of the clarification sludges to be disposed of is achieved thanks to this ultra-sonic treatment.
