Midwest-based Centrisys will provide two American-made decanter centrifuges to Aquarion Water Company for the Stamford, Connecticut Water Treatment Plant Dewatering and Chemical Receiving Facility
Centrisys, a North American manufacturer of decanter and thickening centrifuges and dewatering systems, has secured an order from Aquarion Water Company for two CS21-4HC 2-phase decanter centrifuges for the Stamford, Connecticut Water Treatment Plant Dewatering and Chemical Receiving Facility. In collaboration with consulting engineer Hazen and Sawyer of Wethersfield, Connecticut, the Centrisys CS21-4HC decanter centrifuges were selected to dewater alum sludge generated from the treatment of surface sourced drinking water using a dissolved air flotation and filtration process.
Brian Boyson, New England representative for Centrisys, commented: “Centrisys’ previous susscess working with Aquarion in Stamford, Connecticut facilities was based on our team demonstrating a clear understanding of the critical requirements of the dewatering project and proving our ability to meet or exceed specifications. Aquarion’s previous investment in Centrisys decanter centrifuges at two other water treatment plants in Connecticut established confidence in Centrisys’ ability to meet the high-level process performance and reliability required for the current Stamford water treatment plant processes and specifications.”
Some features of the CS21-4HC decanter centrifuge include Rotodiff hydraulic scroll drive, G-volume and torque capacity, and feed capacity up to 225gpm.
“The Centrisys CS21-4HC centrifuges will provide Aquarion’s Stamford operations team with a higher degree of operational flexibility, the ability to continuously operate at rated flows, and lower overall lifecycle costs for their dewatering operations,” Boyson added.
The Stamford Water Pollution Control Authority processes water from the City of Stamford and the neighbouring town of Darien, and discharges clean water into the east branch of Stamford Habour. Aquarion Water Company, a subsidiary of Eversource, manages the operations for the Stamford, Connecticut Water Treatment Plant Dewatering and Chemical Receiving Facility, and is the public water supply company for approximately 216,000 customer accounts or more than 700,000 people in 58 cities and towns in Connecticut, Massachusetts, and New Hampshire.
