Growth Media Wastewater Treatment Reactor

A treatment system comprising:

• (a) a tank for processing wastewater, said tank having a water level;
• (b) a clarifier positioned in said tank defining a quiescent zone;
• (c) a growth media reactor positioned in said clarifier, said growth media reactor having a least one outer sidewall defining an interior forming a mixing zone, said at least one outer sidewall extending above said water level, said outer sidewall adapted to substantially fluidly isolate, in a region adjacent to said water level, said mixing zone from the exterior of said mixing zone;
• (d) growth media positioned in said interior of said growth media reactor;
• (e) an outlet removing waters from said mixing zone,
• (f) at least one air discharge site adapted to be connected to an air source, said air discharge site positioned so that air released from said air discharge site will substantially flow and disperse upwardly through said growth media
• (g) an inlet feeding wastewaters external to said tank for treatment in said treatment system, said inlet discharging near said air discharge site.

A treatment system comprising:

• (a) a tank for processing wastewater, said tank having a mixing zone and a dilution zone separated by at least one sidewall positioned in said tank;
• said mixing zone having a bottom portion in fluid communication with said dilution zone;
• (b) said dilution zone and said mixing zone having a water level;
• (c) an outlet positioned in said dilution zone, said outlet located at or below said water level in said dilution zone;
• (d) growth media positioned in said mixing zone, said growth media positioned substantially below said water level;
• (e) an air discharge site adapted to be connected to an air source, said air discharge site located near said lower portion of said growth media and positioned so that air released from said air release site will substantially flow upward diffusing only through said mixing zone;
• and
• (f) an inlet positioned in said tank to discharge into said near said air discharge site.

A treatment system comprising:

• (a) a tank for processing wastewater, said tank having a water level;
• (b) a growth media reactor positioned in said tank, said growth media reactor having a least one outer sidewall defining an interior forming a mixing zone, said at least one outer sidewall extending above said water level;
• (c) growth media positioned in said interior of said growth media reactor;
• (d) an outlet removing waters from said treatment system, said outlet exterior to said growth media reactor;
• (e) at least one air discharge site adapted to be connected to an air source, said air discharge site positioned so that air released from said air discharge site will substantially flow and disperse upwardly through said growth media;
• and
• (f) an inlet feeding wastewaters external to said tank for treatment in said treatment system, said inlet discharging into said tank near said air discharge site.
