System and process for reducing PFAS and microplastics in biosolids using hydrodynamic cavitation and foam fractionation

A system for reducing particles from biosolids, comprising:

• a. a storage tank for holding biosolids and an inlet pipe, wherein the inlet pipe delivers biosolids from the storage tank to a screener and then to a percent solids meter operably connected to the inlet pipe, wherein 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;
• b. a chlorine generator operably connected to the percent solids meter, wherein the biosolids are conveyed through the inlet pipe to the chlorine generator from the percent solids meter;
• c. a first venturi hydrodynamic cavitation chamber operably connected to the chlorine generator, wherein the biosolids are conveyed through the inlet pipe to the first venturi hydrodynamic cavitation chamber from the chlorine generator and the first venturi hydrodynamic cavitation chamber creates vacuum bubbles in the biosolids;
• d. a mechanical hydrodynamic cavitation device operably connected to the first venturi hydrodynamic cavitation chamber to receive biosolids through the inlet pipe from the first venturi hydrodynamic cavitation chamber, wherein the mechanical hydrodynamic cavitation device creates vacuum bubbles in the biosolids.
