Abstract
Wastewater sludge is treated by combining the sludge with a carbon-based dielectric additive that includes carbon to yield a modified sludge, irradiating the modified sludge with microwave radiation to yield a treated sludge, and providing the treated sludge to an anaerobic digester.
Claims20
A method of treating wastewater sludge, the method comprising:
- combining the sludge with a carbon-based dielectric additive comprising carbon to yield a modified sludge;
- irradiating the modified sludge with microwave radiation to yield a treated sludge;
- and
- providing the treated sludge to an anaerobic digester.
