Abstract
A waste water treatment method and system including a recirculating treatment zone and a filter/treatment zone. The recirculating zone has a treatment medium that includes aerobic microbes and small beads that create interstices within, and extensive surface area on, which active microbes dwell and through which dead microbes and treated water are permitted to easily pass. The filter/treatment zone has a filter/treatment medium that includes peat and small beads that create interstices through which filtered water is permitted to pass. The recirculating treatment zone is designed to be coupled to a settling unit, such as a septic tank. The filter/treatment zone may be coupled to a leach field, with ultraviolet disinfection for coupling to a secondary water user, a soak hose system, etc. The present invention is sufficiently effective so as to reduce to desirable levels the TSS, BOD, E-Coli, nitrogen-containing compounds, phosphorus-containing compounds, and bacteria of waste water in a manner that is cost-effective and that permits water recycling for many applications.
