Centrisys successfully completes upgrade at New York wastewater treatment plants
A leading North American manufacturer of decanter and thickening centrifuges and dewatering systems announced the $67m (61m euros) energy-efficient upgrade at two of New York City’s largest wastewater treatment plants as complete.
As part of a series designed to improve pollution control and treatment efficiency, the Department of Environmental Protection chose to install 32 American-made CS26-4 Centrisys decanter centrifuges, a Midwest-based company.
The Wards Island Wastewater Treatment Plant is the second largest of the 14 wastewater treatment facilities in the city, serving about 1 million people.
Hunts Point Wastewater Resource Recovery Facility in the south Bronx cleans more than 200 million gallons of wastewater produced by 700,000 residents every day.
Centrifuges are used in the wastewater treatment process to dewater solids or sludge after anaerobic digestion.
The older centrifuges were removed and replaced with newer models in groups of four to ensure the continued operation of the plant throughout the project that began in 2015.
The new Centrisys centrifuges will consume 60 percent less electricity, and reduce 826 metric tons of greenhouses gases annually between the two plants. To date, the upgrade has resulted in savings of $1.1 million per year in power, polymer, and biosolids disposal costs and have greatly improved NYC’s dewatering operational efficiencies.
“With more than 30 years in business, the NYC project exemplifies what our team of engineers can do,” said Michael Kopper, president and chief executive officer of Centrisys. “We take great pride in our technology. Putting systems in place that have an evolving impact on the communities it serves while reducing the environmental footprint and cost of the wastewater treatment process, is of utmost importance.”
The Centrisys engineering team integrated a centrifuge stand, diverter gate, and interconnecting pipework into the NYC plant design. These design elements created a “drop-in-place” centrifuge system, allowing for easy integration with only a few minor modifications to the existing floor plan.
Andy Torres, the Centrisys NYC Project Manager, added: “Although this was a challenging project due to the age of the older system, design of the facilities, the amount of energy required, and the sheer number of individuals dependent on the technology to continue working throughout upgrades, we knew our decanter centrifuges were the ideal solution for NYC.”
