Abstract
A method and system for deselecting biological solids in an influent containing water. The method and system include supplying an influent to an inlet of a reactor comprising at least one of a bioreactor, an internal deselector, a particle deselector, and one or more return lines; dispersing the influent in the bioreactor to form a solid-liquid mixture containing biological solids; retaining, retarding, or providing a differential of, by the internal deselector, biological solids from the solid-liquid mixture to form a deselected solid-liquid mixture and returnable biological solids; feeding said deselected solid-liquid mixture to the particle deselector; deselecting, by the particle deselector, remainder biological solids from the deselected solid-liquid mixture; and supplying, by the one or more return lines, the returnable biological solids to the bioreactor.
