Abstract: Methods and related apparatus for providing a chemical intervention processing solution for use within processing tanks. Processing tanks can include side streams or ancillary systems for generating the chemical intervention processing solution that can then be introduced into the processing tanks. The antimicrobial agents will be added and mixed in the side stream to form the chemical intervention processing solution. Additional actions can be conducted on the processing solution within the side stream including any and or all of heating, pumping, sampling, measuring, testing and pH adjustment of the processing solution. The chemical intervention processing solution can also be provided by a venturi injector that combines processing water and an antimicrobial agent and/or an alkaline agent outside of the processing tank. The processing solution can be used for various food processing applications.
