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.

[ What is claimed is:] [1.] A filter system for continuously removing solid matter from a wastewater, comprising:a first filter chamber having an inlet port and an outlet port;a first filter assembly operably positioned in the first filter chamber between the inlet port and the outlet port;a second filter chamber having an inlet port and an outlet port, the second filter chamber being constructed as a unitary member with the first filter chamber;a second filter assembly operably positioned in the second chamber between the inlet port and the outlet port;means for selectively introducing the wastewater into one of the first and second chambers via their respective inlet ports;means for passing the wastewater through the first filter assembly to separate solid matter from the wastewater so as to produce a first effluent and for discharging the first effluent from the first chamber via the outlet port thereof when the wastewater is being introduced into the first chamber; andmeans for passing the wastewater through the second filter assembly to separate solid matter from the wastewater so as to produce a second effluent and for discharging the second effluent from the second chamber via the outlet port thereof when the wastewater is being introduced into the second chamber.
