Abstract
Oil-water separation apparatus having a flow-through chamber containing a block of foam filter material regenerable by squeezing, a pair of perforated end plates located on either side of the foam block within the chamber at least one of which responds to applied pressure to squeeze the foam, and a flexible envelope of impervious material surrounding the foam block between the block and the inside walls of the chamber and connected at each end to the plates to avoid channeling and friction between the foam block and the walls of the chamber.
