ABSTRACT:
A system for cleanup of waste waters of the type characteristically produced in food-processing operations. Such waste waters typically contain significant amounts of fat and grease materials of animal and plant origin together with other contaminants. Such a starting waste water is charged to the system at a non-uniform rate as generated and is continuously first chemically treated in two successive zones, then is passed into a quiescent holding zone wherein settling can occur and wherein variations in waste water input volume or output volume can be smoothed out. Fluid from the bottom regions of such holding zone is continuously charged at a uniform rate to an operating rotary vacuum filter assembly to accomplish separation of solids. The product water is highly purified.
