It will model the conceptual <br /> process flow diagram: hybrid MWP, aerobic wetland, Pond 42 SRB, and Pond #3 <br /> Anaerobic Wetland with an aerobic discharge. Due to the short schedule available for <br /> testing, Geosyntec recommends two trains for the SRB and downstream wetland so that <br /> we can maintain proof of concept analysis for one train and have the flexibility to <br /> conduct stress tests on the second train. In addition, one of the two SRBs will have a <br /> layer of GAC to evaluate the potential benefits of increasing the available surface area <br /> for biological activity in a cold weather system. A schematic of the pilot-scale testing <br /> set-up is shown in Figure 4. <br /> Treatability Study Work Plan 17 February 8,2018 <br />
