Abstract
An adaptive waste water treatment plant includes an influent intake configured to receive an influent flow from a waste water influent stream. A first settling tank is in a controllable fluid communication with the influent intake. The first settling tank includes a first decanter in fluid communication with a first effluent discharge pipe. A first effluent discharge valve is communicatively coupled to a controller. A first flow meter is in communication with the controller and adapted to measure a rate of flow through the first effluent discharge pipe. A second settling tank is similarly configured. The controller is configured to control the controllable fluid communication between the influent intake and the first settling tank and the controllable fluid communication between the influent intake the second settling tank in response to a change in a rate of influent flow.
