description This invention relates to an improvement in the process for conditioning oil sludges, in which a wire cloth press is used as a separation device forming a pressed cake and including a sludge basin wherein mixing of individual sludges takes place and from which a suspension is removed, and further including intermediate stages for additions assuring the dehydration procedure, the improvement comprising adding structure-improving means to the suspension to increase the shear resistance of the pressed cake and to lower the filtration impedance. The invention also relates to equipment for performing the process.
