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.

[ We claim:] [4.]4. A wastewater treatment system comprising a treatment chamber and a clarifier chamber, said treatment chamber having a floor, said system for treating wastewater having solids therein, said clarifier chamber surrounded from said treatment chamber by a common partition, said clarifier chamber having a top portion and a bottom portion, said common partition defining a shadow zone in said treatment chamber, said partition of said clarifier chamber opening into said treatment chamber near said bottom of said clarifier chamber allowing fluid communication between said treatment chamber and said clarifier chamber, said partition being inclined near the area of said opening, said clarifier chamber being designed so that when wastewater is positioned in said treatment system, some solids suspended in said wastewater in said clarifier chamber settle out and exit said clarifier opening, said treatment system further having a source of air, said air being released into said treatment chamber at a first release location, said first release location being within said shadow zone defined by said inclined portion of said partition, said first release location further being positioned close to said clarifier opening so that air released from said first release location induces an upward current which flows along said inclined partition from close to said clarifier opening to the surface of wastewater positioned in said treatment chamber, said first release location further defined so that said air released from said first location forms bubbles in said wastewater such that substantially all of said bubbles fail to enter said opening in said clarifier chamber.
