Abstract
A method for reducing particles from biosolids, comprising a storage tank for holding biosolids and an inlet pipe. The inlet pipe delivers biosolids from the storage tank to a screener and then to a percent solids meter. The percent solids meter measures the solid content in the biosolids and sends a signal to an electronic solenoid valve to control water content of the biosolids introduced to the system. A first venturi hydrodynamic cavitation to create vacuum bubbles in the biosolids. A mechanical hydrodynamic cavitation device operably connected to first venturi hydrodynamic cavitation, wherein the mechanical hydrodynamic cavitation device creates vacuum bubbles in the biosolids.
