The city of Detroit has selected USFilter to upgrade its secondary wastewater clarifiers as part of the city's effort to eliminate maintenance and operation costs. The stainless steel, corrosion resistant equipment, provided by USFilter's General Filter Products of Ames, IA, will be used for the rehabilitation of the existing 200-foot clarifiers at the Jefferson Avenue Wastewater Treatment Plant.
"Some municipalities use aluminum or fiberglass equipment, but the stainless steel construction virtually eliminates maintenance requirements. This expenditure proves our commitment to specify 'quality', ensure infrastructure integrity, and reduce preventable future expenditures," said Awni Qaqish, PE, the city of Detroit water and sewerage department's assistant director of engineering.
The $5 million USFilter contract includes stainless steel collection troughs (launders), V-shaped weir plates that will be bolted to the troughs for easy adjustment, and scum collection mechanisms for 21 secondary clarifiers at the plant. USFilter will manufacture the equipment at its facilities in Ames and Thomasville, Ga.
The city of Detroit treats approximately 750 million gallons of wastewater per day at the Jefferson Avenue Wastewater Treatment Plant. Serving more than 3 million people in 76 communities, the plant is one of the largest wastewater treatment facilities in the world.
In recent years, USFilter has also supplied technologies to three other Detroit water plants including the Detroit Waterworks Park, Marine Terminal and Detroit River Outfall. Some of the technologies include USFilter's LME systems for surface water treatment, and chlorination/dechlorination and disinfection equipment.
