Abstract
A system for consolidating and removing contaminate such as paint sludge or oils from a fluid mixture. A contaminate tank receives a supply of the fluid mixture containing contaminate from a source such as a manufacturing line where overspray of paints or cleaning solutions containing washed away oils are collected. A free floating weir floats on the surface of the contaminate tank and mechanically separates and removes contaminate from a surface of the contaminate tank and concentrates the contaminate in a consolidation tank. In the consolidation tanks the contaminate is further separated and collected for disposal.
