GreenPoint is designing treatment process improvements for the Sewerage and Water Board of New Orleans' 239-mgd Eastbank WWTP. The improvements include:
Expansion of the plant's Effluent Pumping Station
Converting the plant's WAS Gravity Thickener to a Final Clarifier, and adding a stand-alone WAS thickening process
Implementing improvements to the separation of incinerator fly ash from the treatment process
Enhancing the control of RAS sludge pumping
GreenPoint prepared the engineering design for the process and pumping system improvements at Terrebonne Parish’s North Regional WWTP. GreenPoint evaluated the plant hydraulics, operational requirements and energy demands to design a new 32-mgd primary effluent and return activated sludge pumping system. GreenPoint’s design included variable speed operation, the conversion to submersible operation for improved efficiency and the design of treatment process improvements through the addition of flow instruments to more precisely modulate performance and MLSS concentration within the aeration basin.
