ABSTRACT:
Particles of paint overspray present in floating, and in dispersed form, as well as in submerged and coagulated form are removed from an aqueous turbid liquid. The dispersed and submerged particles of paint overspray form sediment and the sediment is then removed. The sediment is allowed to settle out of a quiescent, turbid liquid onto the bottom of a first tank, whereas the floating particles remain on the surface of the turbid liquid. The sediment is flushed into a second tank by lowering the surface level of the turbid liquid and is then concentrated in this second tank. The surface level of the turbid liquid is then raised and the turbid liquid is allowed to overflow across a flow edge in such a way that the floating particles of the paint overspray are floated off. The turbid liquid, such as turbid water that has been cleansed is drained off.
