ABSTRACT:
A filter system for continuously removing solid matter from a wastewater is provided. The flow of wastewater is automatically alternated between a pair of filter chambers, each of which contain a filter assembly, upon the filter assemblies reaching a predetermined spent condition. As the wastewater is being introduced into one of the filter chambers, the filter assembly in the other filter chamber is automatically backwashed and readied for another filtering cycle. Each filter assembly includes a filter element coated with a diatomaceous earth filter media through which the wastewater is drawn by creating a vacuum downstream of the filter assembly.
