The San Bruno Water Quality Control Plant (WQCP) in South San Francisco, CA, uses primarily settling treatment followed by an aerated-activated sludge process for removal of organics and other constituents from the wastewater. The activated sludge process has two parallel trains of activated sludge treatment. Each train has multiple aeration tanks and multiple air blowers to provide air for the treatment process.
