ABSTRACT:
A sludge harvester for removing a concentrated nutrient sludge from a sludge pond includes a frame, one or more wheels or skids attached to the frame, means for gently breaking up at least a portion of the sludge layer adjacent to a dilute layer, and means for capturing at least a portion of the broken up sludge layer. The organic sludge product recovered by the harvester has a higher nutrient concentration as compared to alternative methods because of minimized mixing of the sludge and dilute layers during collection of the organic sludge product. The organic sludge product captured by the harvester can be applied directly to agricultural land or used in the production of a certifiable organic or other fertilizer.
