ABSTRACT:
Apparatus is disclosed for separation of liquid and solid waste materials from a mixture or other combination of such materials. A container is provided with a vertically disposed interior screen or perforated wall that is capable of retaining solid material while permitting liquid material to pass therethrough. The perforated wall divides the container into first and second portions. Waste material is provided to the first portion, and liquid material is removed from the second portion. Preferably disposed in the first portion is an onion bag or other porous, screening or filtering material for receiving the combination of liquid and solid material and retaining of the solid material. Liquid material can be removed from the second portion via a drain, or alternatively by a pump controlled by a liquid level sensor. The pump would be operated whenever the liquid level sensor sensed a sufficiently high predetermined level of liquid in the container.
