Abstract:
The present invention is a self-regenerating biofilter. The biofilter tank receives untreated water through an intake inlet, filters it through a filtration mass and expels purified water through an output outlet. The filtration mass includes gravel and activated carbon layers separated by a mesh screen. A compressed air line is located below the mesh screen. Periodically, the biofilter self-cleans by opening a flush valve that expels a flush water stream carrying debris. The biofilter self-regenerates by periodically stopping filtration for a time, allowing biological matter left on the activated carbon to degrade into biomass. Periodically, the biofilter removes and flushes out biomass by application of water or a combination of air and water.

Claim (Index 24):
The method of  claim 21  wherein said filtration mass makes up approximately 50% to approximately 85% of a volume of said biofilter tank, wherein said layer of gravel comprises approximately 3% to approximately 10% of said filtration mass, wherein said layer of activated carbon comprises approximately 60% to approximately 97% of said filtration mass.
