Abstract
Abstract Apparatus for removing floatable matter (commonly referred to as ''''floatables'''') from rubbish prior to the subsequent treatment thereof. The rubbish is deposited in a water-filled tank and the water is agitated to break up and thoroughly wet all particles. The floatables are swept over a spillway onto a first conveyor exterior of the tank, which conveyor removes the floatables to another location for further processing. A second conveyor removes that portion of the rubbish which sinks to the bottom of the tank.
