ABSTRACT:
An upflow filter adapted to be used with a home sewage treatment plant which includes a container which has a wall extending thereacross to divide the container into first and second filtering chambers. First and second gratings are located in the first and second chambers respectively and serve to divide each filtering chamber into top and bottom portions and each grating has filtering media covering the same. The container has an inlet and an outlet with the outlet located at a lower level from the inlet. First liquid conduit means are connected to the wall and provides for fluid communication from the inlet to the bottom portion of each of the first and second filtering chambers. Second liquid conduit means are connected to the wall and provides for fluid communication from the top portion of each of the first and second filtering chambers to the outlet. A variation of the invention involves the providing of a cut out in the dividing wall so that filtered material will exit both filtering chambers in the event the filter is not set or installed perfectly level. The foregoing abstract is merely a resume of one general application, is not a complete discussion of all principles of operation or applications and is not to be construed as a limitation on the scope of the claimed subject matter.
