RED TECHNOLOGIES, LLC Environmental Remediation Division Modifies the Q-Bridge Central Groundwater Treatment Facility

Published on March 28th, 2012
BACKGROUND

New Haven, CT - RED TECHNOLOGIES, LLC is currently contracted through the Connecticut Department of Transportation to manage and operate the Central Groundwater Treatment Facility (CGWF) on the estimated $450 million dollar Q-Bridge project located in New Haven, CT. All impacted groundwater encountered during construction activities on this project is conveyed and/or transported to this facility from various contractors and is remediated compliant to the Connecticut Department of Energy and Environmental Protection (CT DEEP) General Permit for the Discharge of Remediated Wastewater to a Sanitary Sewer.

WORK PERFORMED

Recently, modifications to the CGWF were conducted based on substantial deterioration of the existing groundwater treatment components. Deterioration occurred due to excessive rusting as a result of treating brackish groundwater.

Modifications included the replacement of four 8,000 lb steel granular activated carbon vessels with four 6,600 lb fiberglass reinforced plastic (FRP) vessels. In addition, the steel manifold used to convey the process water through the series of vessels was redesigned and replaced with Schedule 80 polyvinyl chloride (PVC) pipe, fittings and valves.

RESULTS

The redesign and modifications of the CGWF performed by RED TECHNOLOGIES, LLC:

• Reduces overall operating pressures by 50% while simultaneously increasing treatment flow rates by 12-15%.
• Allows the treatment facility to operate at lower operating pressures creating a safer work environment for employees.
• Increases system efficiencies while reducing overall operating energy costs.
• Lowers the overall costs of the project through optimal material selection, assuring operation for many years to come.
