Abstract
A method of activating and dewatering sludge through application of acoustic pressure shock waves to wastewater.
Claims19
A method comprising applying acoustic pressure shock waves that have a compressive phase producing high compressive pressure and a tensile phase producing cavitation bubbles that collapse with high speed jets to sludge in a liquid containment.
A sludge treatment system comprising a containment with wastewater and sludge that has a fluid surface and an acoustic pressure shock wave device movable across the fluid surface and having a generator that produces acoustic pressure shock waves into the sludge, wherein the acoustic pressure shock wave device floats at the fluid surface.
A sludge treatment system comprising a containment with wastewater and sludge that has a fluid surface and an acoustic pressure shock wave device movable across the fluid surface and having a generator that produces acoustic pressure shock waves into the sludge, and further comprising one or more aerators in the wastewater.
A sludge treatment system comprising a containment with wastewater and sludge that has a fluid surface and an acoustic pressure shock wave device movable across the fluid surface and having a generator that produces acoustic pressure shock waves into the sludge, and further comprising at least one of a filter and filter media positioned in the in the containment beneath the fluid surface.
