A 5 mgd tertiary wastewater treatment plant was constructed to demonstrate treatment of effluent from a 5 mgd step aeration activated sludge plant. The two-stage high lime process with intermediate recarbonation, filtration and activated carbon adsorption operated at the design rate for 36 days between two failures of the reactor clarifiers. A single-stage low lime process with filtration and activated carbon adsorption operated for 89 days. The combined secondary and tertiary treatment removed > 97% of BOD, TSS and P in the raw wastewater. Capital cost of the 5 mgd two-stage high lime system was 4.7 million dollars and operating costs were estimated as 36 cents per 1000 gallons of wastewater.
