  • RBC with solids contact zone
    Patent number: 4721570
    Abstract: A method and apparatus for enhancing the settleability of suspended wastewater solids is provided for a wastewater treatment system comprising a primary clarifier apparatus, a compartmentalized, sequential secondary biological treatment apparatus such as a rotating biological contactor tank, and a secondary clarifier, wherein a portion of waste sludge from the clarifier is diverted to compartments of the rotating biological contactor tank to enhance the flocculation of the suspended waste solids. The diverted sludge particles serve as flocculation nuclei which promote settleability and lower turbidity once the effluent reaches the secondary clarifier.
