  • Self-regenerating biofilter
    Patent number: 10494272
    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.
