Continuous flow reactor wastewater treatment plant

A wastewater treatment tank having a bottom, an open top, and a continuous side wall extending between the top and the bottom, the bottom of the treatment tank having a bio-sludge outlet, the tank comprising:

• an inverted frustoconical partition connected to the side wall of the treatment tank intermediate the bottom and the top thereof, the partition having an upper surface, a lower surface, and an opening defined therein and spaced from the bottom of the tank, the partition dividing the treatment tank into an upper aeration chamber and a lower clarification chamber;
• a wastewater inlet line opening into the aeration chamber of the treatment tank;
• an effluent discharge outlet line having an intake end positioned within the clarification chamber and an outlet end external of the tank;
• and
• an aerator positioned within the aeration chamber to supply air to the wastewater within the aeration chamber.

An apparatus for treating wastewater comprising:

• a tank having a bottom, an open top, and a continuous side wall extending between the top and the bottom, the bottom of the treatment tank having a bio-sludge outlet, the top of the tank having a peripheral edge;
• an inverted inclined partition connected to the side wall of the treatment tank and spaced from the bottom of the treatment tank, the inclined partition having an upper surface, a lower surface, and an opening defined therein, the side wall of the tank and the upper surface of the inclined partition defining an upper aeration chamber, the side wall of the tank, the lower surface of the inclined partition, and the bottom of the tank defining a lower clarification chamber;
• a wastewater inlet line opening into the aeration chamber;
• an effluent discharge outlet line having an intake end positioned within the clarification chamber and an outlet end external of the tank;
• and an aerator positioned within the aeration chamber.

A system for treating wastewater having bio-solids therein, comprising:

• a tank having a bottom, an upper aeration chamber, and a lower clarification chamber, the upper aeration chamber separated from the lower clarification chamber by a common inclined partition having an opening defined therein, the inclined partition opening into the clarification chamber near the bottom of the tank and allowing fluid communication between the upper aeration chamber and the lower clarification chamber, the bottom of the tank having a bio-sludge outlet for removal of settled bio-solids;
• a wastewater inlet line opening into the aeration chamber;
• an effluent discharge outlet line having an intake end positioned within the clarification chamber and an outlet end external of the tank;
• and
• an aeration source positioned within the aeration chamber.

A method for treating wastewater comprising:

• providing a tank having a bottom, an upper aeration chamber, and a lower clarification chamber, the aeration chamber separated from the clarification chamber by a common inclined partition having an opening defined therein, the partition opening into the clarification chamber near the bottom of the tank allowing fluid communication between the aeration chamber and the clarification chamber, the bottom of the tank having a bio-sludge outlet in communication with the clarification chamber;
• suppling wastewater to the aeration chamber;
• aerating the wastewater within the aeration chamber;
• passing aerated wastewater though the inclined partition opening and into the clarification chamber;
• settling bio-solids within the clarification chamber to the bottom of the tank;
• removing effluent from the clarification chamber of the tank;
• removing settled bio-solids from the clarification chamber of the tank via the bio-sludge outlet of the tank;
• and
• supplying a portion of the removed settled bio-solids to the aeration chamber of the tank.

A system for treating wastewater having bio-solids therein, comprising:

• a tank having a bottom, an upper aeration chamber, and a lower clarification chamber, the upper aeration chamber separated from the lower clarification chamber by a common inclined partition having an opening defined therein, the inclined partition opening into the clarification chamber near the bottom of the tank and allowing fluid communication between the upper aeration chamber and the lower clarification chamber, the bottom of the tank having a bio-sludge outlet for removal of settled bio-solids;
• a wastewater inlet line opening into the aeration chamber;
• an effluent discharge outlet line having an intake end positioned within the clarification chamber and an outlet end external of the tank;
• a bio-sludge recirculation conduit having a first end in communication with the bio-sludge outlet and a second end opening into the aeration chamber of the treatment tank so that a portion of the bio-sludge removed from the clarification chamber of the tank is passed into the aeration chamber;
• and
• an aeration source positioned within the aeration chamber.
