Abstract: Mixtures of organic materials, solids and water, e.g. wastes, are treated with solvents to remove the organic materials. A first extraction with a first organic solvent gives an intermediate composition which is treated with a volatile organic solvent capable of dissolving at least some of the first solvent to give a treated product.

Abstract: Appts. for sepg. extractable organic material from sludge, in which appts. for conditioning an extrudable compsn. contg. organic material for sepn. of the organic material therefrom, comprises (a)ma contactor vessel for organic material sepn.; (b) a conveyor having conduit for conveying the extrudable compsn. to the contactor vessel; and (c) a cutter for reducing the extrudable compsn. conveyed by the conveyor through the conduit to reduced cross-section extrudates for deposition in the contactor vessel. Pref. process comprises (i) forming a fixed porous bed of the compsn. in a contactor vessel; (ii) contacting the compsn in the bed with organic solvent(s) capable of dissolving the extractable material to forn an effluent contg. the solvent and extractable material; and (iii) admitting water into the contactor vessel for flow through the bed to displace residual effluent remaining in the vessel and partially filling the vessel with water.
