The City of Valdosta, Georgia owns and operates a 12 mgd wastewater treatment plant (WWTP) that discharges into the Withlacoochee River. The WWTP, located in the 100-year floodplain, includes primary clarifiers, roughing towers, aeration basins, secondary clarification, chlorination/de-chlorination, post aeration and subsequent discharge into the river.
Due to the deteriorating condition of the primary clarifiers and roughing towers, the two unit processes had been bypassed. This in turn caused the aeration basins and secondary clarifiers to be overloaded, necessitating the wasting of sludge at higher rates than the original design capacity at the WWTP. To address this challenge, Constantine was contracted to provide a fully functional 2-meter Ashbrook Winklepress on a trailer in less than 4 months.
Even though the typical lead time for the delivery of a belt filter press can be 6 months or more, our team was able to complete the entire project in less than 5 months from contract award to belt filter press start-up.
This project is representative of the innovation, quality, cost, and timeliness that Constantine's work embodies.
