A device for and method of separating solids from liquids, where necessary with initial emulsion breaking, precipitation, coagulation and/or flocculation treatment to convert emulsified, dissolved, and/or suspended contaminants into separable solids, comprises a treatment chamber (1) having a piston (7) movable therein between a start position in the upper part of the chamber and an end position in the lower part of the chamber, drive means outside the chamber for moving the piston, a liquid inlet (8) below the piston in the start position thereof, a treatment agent and mixing inlet (21 to 23), an outlet (3) for the discharge of solids below the piston in the end position thereof, and a liquid outlet (27 to 31) above the piston in the end position thereof, the inlets and the outlets being controlled by valves (4, 9, 24 to 26, 32 to 36), the piston (7) being permeable to the liquid but substantially impermeable to the solids.
