<p>A solid waste retrieval device (11) utilizes a rotating drum (26) carrying a plurality of teeth (37) to lift dried sludge from an underlying sand bed such that substantially no sand is removed with the sludge. The device moves over the sludge and compresses it beneath a forward rolled radius section (17) to prevent buckling and disruption of the sludge ahead of the device.</p> |
