Centrisys/CNP to supply 12 decanter centrifuges for MSD project clear major solids management upgrade

North American manufacturer of decanter centrifuges and advanced biosolids treatment technologies Centrisys/CNP has announced its role in the Metropolitan St Louis Sewer District Project Clear (MSDPC) solids management upgrade (SMU) to its Bissell point and Lemay wastewater treatment facilities. Making investment in cleaner technology, MSDPC will replace existing units with new advanced solids management equipment and processes. The SMU design-build project, led by Kokosing/Plocher (KP), will see the deployment of 12 Centrisys/CNP CS30-4DT 2 phase decanter centrifuges — six at Bissell point and six at Lemay. These units will form a part of the new solids handling processes.

The US$900m SMU project will improve air quality, increase energy efficiency, lower operating and maintenance (O&M) costs, and create more than 200 new jobs

“Our appointment as the exclusive vendor for decanter centrifuges for this project underlines the quality and reliability of our products,” said Josh Gable, sales director for Centrisys/CNP. “The new systems will provide cleaner water and air for the St Louis region, underscoring MSDPC’s commitment to the environment and human health.”

Features of the Centrisys/CNP CS30-4DT 2-Phase decanter centrifuges include Rotodiff hydraulic scroll drive — Centrisys’ standard back drive, highest G-volume and torque capacity, and feed capacity up to 700 gallons per minute (GPM). It is said to have the lowest installed combined horsepower (hp) of 275hp in its size specification, increased solids handling to reduce polymer consumption and an auto lube system. The US designed and built decanter centrifuges also have regional centrifuge service and repair facility.

KP preselection of equipment supplier Centrisys/CNP for decanter centrifuges showcased its design input, project RFP support, pricing, and field operations management which reportedly achieved the lowest cost for MSDPC.

MSDPC owns and operates seven wastewater treatment facilities treating an average flow of 350 million gallons of wastewater per day. The Bissell Point and Lemay wastewater treatment facilities are the two largest plants, both serving the Mississippi river watershed. As part of MSDPC, it is increasing wastewater collection and treatment capabilities that project officials state is a decades-long task in the region with nearly 10,000 miles of public wastewater and stormwater sewers — reportedly the nation’s fourth largest.
