Camp Merrill Wastewater Treatment Facility
The U.S. Army Ranger Mountain Course was completed in the mountains of North Georgia at Camp Merrill. Camp Merrill is situated in the mountains of the environmentally sensitive Chattahoochee National Forest, adjacent to a critical cold water trout stream. The Army recognized the need to make major changes to its wastewater treatment system through an intense analysis with GMC in a joint venture. A membrane bioreactor (MBR) system was selected to reduce the footprint of the treatment system, reclaim valuable land from the lagoon for mixed purpose use, and provide the highest quality effluent. The design required fine screening to protect the membranes in the bioreactor from fouling. GMC utilized a JWC roughing screen with a vertical auger for coarse screening at the influent pump station. After coarse screening, the wastewater is conveyed through two 2-mm fine screens prior to the biological process. The screens also provide separation for the return activated sludge to provide additional protection to the membranes. The Kruger MBR treatment train provides reuse quality water where the design utilized ultraviolet disinfection with the capability of inducing chlorine with the use of an onsite disinfection system to provide residual chlorine. The treated effluent design allows for the water to be contained for land application or for reuse distribution around the camp for activities such as vehicle washdown. The closing of the lagoon provides additional space for base operations and is irrigated by the reuse system. In addition to the treatment, a laboratory and office facility was designed and constructed that included SCADA and instrumentation to support operation. To contain the inflow and infiltration from the years of expansion on base, the entire collection system was replaced with ductile iron pipe and all storm water inlets removed from the sewer collection system.
