Patent ID: 7488409

Claim:
A process for treating and oxidizing animal waste materials comprising disposing an electrolyte in an electrochemical cell, separating the electrolyte into an anolyte portion and a catholyte portion with an ion-selective membrane or semipermeable membrane applying a direct current voltage between the anolyte portion and the catholyte portion, placing the animal waste materials in the anolyte portion, and oxidizing the animal waste materials in the anolyte portion with a mediated electrochemical oxidation (MEO) process, wherein the anolyte portion further comprises oxidizing species as a mediator in aqueous solution and the electrolyte is an acid, neutral or alkaline aqueous solution, further comprising introducing an ultrasonic energy into the anolyte portion, rupturing cell membranes of biological cells in the animal waste materials by momentarily raising local temperature within the biological cells with the ultrasonic energy to above several thousand degrees, and causing cell membrane failure.
