Abstract

A wastewater treatment plant (700, 800, 1000, 1100) that employs an activated sludge process and a method of operating the same is described. Wastewater influent is provided to a bioreactor (602, 1006) configured to perform activated sludge processing to develop mixed liquor suspended solids (MLSS). The MLSS is passed from the bioreactor (602, 1006) to a hydrodynamic separator (HDS) system (702, 802, 1010), where separation operations are performed on the MLSS. The separation operations generate a low concentration MLSS stream and a high concentration MLSS stream. The low concentration MLSS stream is passed from the hydrodynamic separator system (702, 802, 1010) via a first output to a clarifier (604, 1012), and the high concentration wastewater stream is passed via a second output back to the bioreactor (602, 1006). The clarifier (604, 1012) performs clarification operations on the cleaned wastewater stream and then outputs an effluent flow.
