Abstract

1,205,112. Treating painting process effluents. LANCY -LABORATORIES Ltd. 3 March, 1969 [8 March, 1968], No. 11567/68. Heading C1C. A process for the treatment of aqueous effluents obtained from the rinsing of electrodeposited paint films comprises the precipitation and removal by sedimentation or filtration of paint material by adding a first chemical and treating the remaining first chemical with a second chemical to form a substance which is chemically inert to the paint film. At least part of the treated water may be returned to the rinsing stage of the process. The first chemical may be an acid (or an alkali) which is subsequently removed by addition of a stoichiometrically equivalent amount of an alkali (or an acid). Mineral acids, e.g. hydrochloric acid, or organic acids may be used and preferred alkalis are sodium hydroxide and ammonium hydroxide.
