Abstract:
1. A wastewater treatment system comprising: a reactor having an inlet end, an outlet end, a left side, a right side and a floor; an inlet proximate said reactor inlet end for introducing wastewater to said reactor; a first bio medium generally submerged and extending substantially between said reactor left and right sides and extending substantially between a top water level and said reactor floor, said first bio medium being a permeable hydraulic barrier adapted for allowing said wastewater to flow generally uniformly therethrough; an aeration system adapted for mixing and aerating said wastewater; a second bio medium generally submerged and extending substantially between said reactor left and right sides and extending substantially between a bottom water level and said reactor floor such that a top of said second bio medium is located at a height generally equal to a height of said bottom water level, said second bio medium being a permeable hydraulic barrier adapted for allowing said wastewater to flow therethrough; and an outlet proximate said reactor outlet end for discharging treated wastewater from said reactor, said outlet including an orifice positioned at a height generally equal to said height of said top of said second bio medium and said height of said bottom water level such that said orifice is positioned for withdrawing treated wastewater from an upper portion of said reactor located above said top of said second bio medium, wherein a majority of said treated wastewater discharged from said reactor passes over said top of said second bio medium.
