Claim:
A method for treating wastewater comprising the acts (steps) of: treating a first influent in a blackwater treatment train, the blackwater treatment train comprising the acts (steps) of: screening the first influent in a blackwater screening zone, clarifying a blackwater screening zone effluent in a clarifying zone, reducing sludge from the clarifying zone in a sludge reduction zone, filtering clarification zone effluent in a blackwater filtration zone, advanced oxidation of a blackwater filtration zone effluent (permeate) in a blackwater advanced oxidation zone, and discharging a blackwater advanced oxidation zone effluent, treating a second influent in a graywater treatment train, the graywater treatment train comprising the acts (steps) of: screening the second influent in a graywater screening zone, treating screened solids from the graywater screening zone in the sludge reduction zone, filtering a graywater screening zone effluent in a graywater filtration zone, treating filtered solids (retentate) from the graywater filtration zone in the sludge reduction zone, advanced oxidation of a graywater filtration zone effluent (permeate) in a graywater advanced oxidation zone, and reusing an advanced oxidation zone effluent.
