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 21):
A method for using a self-regenerating biofilter apparatus to purify water containing contaminants, said method comprising the steps of:\n receiving an untreated water stream into a biofilter tank through an intake inlet, filtering said untreated water stream through a filtration mass to transform said untreated water stream into a purified water stream, wherein said filtration mass removes water contaminants by straining/screening, adsorption and/or biological remediation, expelling the purified water stream through an output outlet connected to a second channel; periodically stopping filtration for a time by stopping receiving the untreated water stream; opening a flush valve; draining a flush water stream through the flush valve; closing the flush valve wherein biodegradable contaminants in said untreated water stream provide food for microorganisms in said filtration mass and become biomass during a controlled time period, and periodically performing a biomass removal wherein said self-regenerating biofilter receives an influx of untreated water stream through said intake inlet, opening said flush valve, and draining a biomass debris containing flush water stream through said flush valve.
