Project
Hurricane Katrina sent ripples far beyond the Gulf Coast, ultimately affecting construction material prices throughout the nation. At the time, the City of Claremore, Oklahoma planned to build a new regional wastewater treatment plant, but skyrocketing costs required officials to consider other options.
After Garver analyzed 17 alternatives, officials approved a plan to incorporate a completely new treatment process at the existing site. This conversion has increased the future treatment capacity within the facility’s footprint and integrated advanced technologies to produce higher quality effluent.
Garver’s design included upgrades to every single process at the plant, converting it from a fixed-film trickling filter system to an advanced activated sludge treatment process with biological nutrient removal (BNR) capabilities.
Garver partnered with the Oklahoma Department of Environmental Quality to obtain targeted design variances. These variances translated into reduced capital expenditures by retrofitting existing concrete structures for new treatment processes.
The upgrades included a new headworks to remove floating debris and grit before water enters the plant, converting trickling filters to roughing filters to increase organic and hydraulic loadings, an advanced activated sludge process, and clarifier upgrades.
Additional improvements included a complete overhaul of the existing solids handling processes, including new aerobic digestion, gravity thickening of primary sludge, new gravity belt thickening and new belt-filter press dewatering.
Together, the new treatment process is helping the Claremore plant produce effluent well below permit levels for biochemical oxygen demand (BOD), total suspended solids (TSS) and ammonia (NH3).
