Abstract:
1. A sludge removal and tank cleaning system comprising: an external tank conduit placed in fluid communication between an outlet of a sludge containing tank and a jet nozzle inlet of the sludge containing tank; a grinder pump coupled to the external tank conduit to receive unfiltered sludge from the outlet, the grinder pump configured to receive the sludge at a first pressure and with sludge solids at a first size, and to pressurize the sludge to a second, increased pressure and to grind the sludge solids to a second, reduced size thereby outputting a flowable slurry in the external tank conduit; and a positive displacement pump coupled to the external tank conduit downstream of the grinder pump, the positive displacement pump configured to receive the flowable slurry at the second, increased pressure, to pressurize the flowable slurry to a supercharged pressure, and to output the supercharged flowable slurry to the jet nozzle inlet for jet streaming the flowable slurry from the jet nozzle onto the settled sludge to mechanically condition the settled sludge, whereby the flowable slurry is removable from the tank; wherein the external tank conduit, the jet nozzle, the grinder pump, and the positive displacement pump are attachable to and removable from the sludge containing tank.
