Major wastewater dewatering system upgrade to occur in NY

Centrisys Corporation began a purchase order to replace 13 dewatering centrifuge systems at Wards Island WWTP in New York City.

KENOSHA, WI, Oct. 11, 2013 -- Centrisys Corporation has begun fulfilling a purchase order to replace 13 dewatering centrifuge systems at the Wards Island Wastewater Treatment Plant in New York City, N.Y. -- one of the largest current wastewater treatment projects in the United States.

The project is part of a series of upgrades to improve pollution control and treatment efficiency at Wards Island, which is the second largest of the city's 14 wastewater treatment facilities and serves about 1 million people with an average dry-weather flow capacity of 275 million gallons per day. The total cost of the project is $9 million. The first three Centrisys CS26-4 dewatering centrifuges will ship in May 2014, with the remaining 10 centrifuges to follow in early 2015.

Before awarding the contract, the NYC Department of Environmental Protection enlisted CDM Smith, one of the world's foremost water quality consulting firms, to compare five available dewatering centrifuge models of similar capacity: Alfa Laval G2-115, Andritz CP4-1.2 (a retrofit, using same frame), Andritz D6LX, Westfalia CF 7000, and the Centrisys CS26-4. Using a matrix incorporating an array of weighted criteria -- including design, installation, performance, maintenance, and cost parameters -- CDM Smith ranked the products and manufacturers by their total scores.

"World-class wastewater treatment facilities, like those in New York City, have some very important and demanding criteria for dewatering systems -- in terms of design, performance and installation," said Michael Kopper, Centrisys president. "We've been listening and responding to these challenges for decades. And that's why our system came out ahead in this case."

Like other Centrisys dewatering systems, the CS26-4 features a 15-degree beach angle, proven through rigorous testing to deliver optimal clarification volume for municipal wastewater treatment; a Rotodiff® hydraulic scroll drive by Viscotherm AG for higher torque at lower energy consumption than the traditional gearbox; and centrifugally-cast duplex stainless steel bowl components for higher strength and corrosion resistance.
