Disclosed is a continuous process for removing an organic compound from water including passing an influent of water and organic compound through a filter bed of hard, substantially non-porous, inorganic particles to separate the organic compound and form a water effluent of reduced organic amounts, washing the particles to remove the organic compound and form a concentrated organic effluent, and recycling washed particles to the filter bed. The continuous process includes washing at a washing rate sufficient to shear organic compounds from solid filter media particles.

A continuous physical separation process for purifying water contaminated with low level concentrations of PCB\s without replacement or disposal of filter bed media comprising: (a) passing water contaminated with low level concentrations of PCB\s in the range of about 1-20 ppb through a filter bed of hard, substantially non-porous, inorganic particles to separate said PCB\s and form contaminated particles and purified water of reduced PCB\s concentration; (b) hydraulically shearing said contaminated particles to remove said PCB\s and form decontaminated particles and a concentrated PCB\s effluent; and (c) recycling said decontaminated particles to said filter bed.
