A reactor chamber for placement in a wastewater treatment system, where the reactor chamber has a chamber formed from a sidewall which forms an interior of the chamber. The sidewall has a top portion and a bottom portion and fixed channel growth media positioned in the interior of the chamber. The fixed channel growth media is positioned below the top of the sidewall, so that when positioned in a treatment system, most of the growth media is located below the water level in the treatment system. The top of the sidewall near the water level (when positioned in a treatment system) is substantially impermeable to wastewater. The reactor includes an air distribution manifold system having a series of air release sites positioned below the fixed channel growth media and adapted to release air which disperses upwardly through the fixed channel growth media. Influent is discharged into the treatment tank near the air discharge sites.

Growth media wastewater treatment reactor

The present invention is a method for reducing the nitrate concentration in wastewater within a wastewater treatment apparatus configured to define an aeration zone and a quiescent zone or dilution zone. The method comprises the step of ceasing airflow into the aeration zone for a predetermined time period or until the dissolved oxygen level within the wastewater has reached a predetermined threshold. The method also comprise the step of mixing the wastewater in the aeration zone to prevent suspended particles within the wastewater in the aeration zone from settling and to avoid substantially disturbing the quiescence of the quiescent zone.

A wastewater treatment system having a treatment chamber and a clarifier chamber, the treatment chamber having a floor, the clarifier chamber separated from the treatment chamber by a common partition, the clarifier chamber having a top portion and a bottom portion, the clarifier chamber having an opening into the treatment chamber near the bottom of the clarifier, where the common partition is inclined near the area of the clarifier opening, and clarifier chamber being designed so that when wastewater is positioned therein, some solids suspended in the wastewater in the clarifier chamber settle out and exit the clarifier opening, a current in the wastewater in the treatment chamber, where the current passes across the floor of said treatment chamber near the opening of the clarifier, the current being sufficient to substantially prevent a build up of solids on the treatment chamber floor beneath the clarifier opening where the current does not keep all solids within said treatment chamber suspended within the treatment chamber.
