Abstract

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.
