  • Integrated hydroponic and wetland wastewater treatment systems and associated methods
    Patent number: 7320752
    Abstract: The wastewater treatment systems have a plurality of treatment modules between the inlet and the outlet, each for treating water with a selected process. Influent is directed to a covered anaerobic reactor, and then to an attached growth pretreatment filter that is at least intermittently exposed to atmospheric oxygen. Following the filter is a hydroponic reactor followed by a vertical-flow wetland. A second embodiment includes, following the filter, a tidal vertical-flow wetland and a pump for recycling water exiting the wetland upstream of the filter.
    Type: Grant
    Filed: December 13, 2004
    Date of Patent: January 22, 2008

  • Integrated hydroponic and wetland wastewater treatment systems and associated methods
    Patent number: 6830688
    Abstract: The wastewater treatment systems have a plurality of treatment modules between the inlet and the outlet, each for treating water with a selected process. Influent is directed to a covered anaerobic reactor, and then to an attached growth pretreatment filter that is at least intermittently exposed to atmospheric oxygen. Following the filter are a first and a second hydroponic reactor in series, followed in turn by a vertical-flow wetland. A second embodiment includes, following the filter, two or more tidal vertical-flow wetlands in series, and a pump for recycling water exiting the final wetland upstream of the filter.
