<p>A treatment system is provided which can treat solid materials and/or liquid materials. Preferably, a separator (10) initially separates liquid and solid materials, and the solid materials are deposited in a microwave reaction chamber (12) to be subjected to microwaves. The liquids exiting the separator are preferably also passed through a filter assembly (26) which retains any suspended particles remaining in the liquid, and subjects the particles to microwaves. Exhaust filter (20) can also be provided for the microwave reaction chamber (12).</p>
