Abstract

See full text

An advanced control system for a membrane bioreactor based wastewater treatment plant is disclosed. The disclosed control system comprises a membrane bioreactor (MBR) system and a microprocessor based controller that receives signals corresponding to selected measured MBR parameters and calculates or estimates one or more MBR calculated parameters including Membrane Conductivity (Fxc); and/or Oxygen Uptake Rate (OUR). The microprocessor based controller compares one or more calculated or estimated MBR parameters to prescribed setpoints or desired ranges and governs one or more pumps and valves in the MBR system to adjust the cleaning cycle in the MBR system, the MBR flows in the MBR system, or the influent flow to the biological basin in response thereto.
