A system can include a multi-material fluid having a mixture of a first material and a second material. The system can also include a first vessel into which the multi-material fluid is disposed. The system can further include a first sonication device disposed, at least in part, in the multi-material fluid in the first vessel. The first sonication device, when operating, can emit ultrasound waves into the multi-material fluid. The ultrasound waves separate the first material and the second material from each other in the first vessel.

Sonication for separation of materials in fluids

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.

Additive-amplified microwave pretreatment of wastewater sludge

A soil remediation method for treating contaminated soil includes combining a dielectric carbonaceous nanomaterial with the contaminated soil to yield a composite contaminated soil, and irradiating the composite contaminated soil with microwave radiation to yield a remediated soil. The composite contaminated soil includes at least 1 wt % of the dielectric carbonaceous material, and the microwave radiation provides an energy input of at least 2.5 kWh per kilogram of the composite contaminated soil.
