ABSTRACT:
A method and an apparatus for the purification and treatment of liquids which are used for cooling and/or lubricating and contain impurities of metal and other materials, particularly for separating scale from the process water of cooling cycles in the metallurgical industry, wherein the liquid to be purified flows through intermediate spaces between plates arranged parallel next to each other in a container, and wherein the plates are arranged horizontally and are moved upwardly and/or downwardly transversely of the flow direction of the liquid. The solid particles are removed from the process water by sedimentation on the plates and additionally by a magnetic force which emanates from the upper sides of the plates.
