<p>of the Invention To separate solid and liquids contained in aqueous dispersions of solids, which may also be oil-bearing, a flocculating agent is added to the dispersion while flowing through a pipe, the flowing aqueous dispersion then subjected to a flow restriction to mix the flocculating agent and flocculate the solids and the thus treated dispersion discharged onto a surface permitting free liquid run-off and deposition of the floc. The process is particularly applicable to oil-bearing waste water sludges and waste oil sludges. The process facilitates recovery of the oil and land forming of the solids.</p> |
