Method and system for pre-treating high strength wastewater

A system for use with a wastewater treatment plant for pre-treating high strength wastewater, wherein the system comprises:

• a first reactor that is operationally couplable to the wastewater treatment plant and is configured to receive the high strength wastewater from a high strength wastewater source, receive waste activated sludge from the wastewater treatment plant, form a mixed liquor from the high strength wastewater source and the waste activated sludge, aerate the mixed liquor, separating the mixed liquor to form a clarified supernatant and a biomass, and provide the clarified supernatant to a liquid treatment train of the wastewater treatment plant;
• a second reactor that is coupled to the first reactor, the second reactor being configured to receive the biomass from the first reactor, aerate the biomass, and provide the aerated biomass to a solid treatment train of the wastewater treatment plant;
• one or more sensors;
• integrated aeration equipment or external aeration equipment for performing aeration in first and second reactors;
• and
• a control system that is coupled to the first and second reactors and configured to control one or more aspects of a treatment process performed by the first and second reactors including the aeration in the first and second reactors based on data measured by the one or more sensors.
