It modeled the conceptual <br /> process flow diagram: hybrid MWP, aerobic wetland, Pond#2 SRB, and Pond#3 <br /> Anaerobic Wetland with an aerobic discharge sand filter. Due to the short schedule <br /> available for testing, two trains for the SRB and downstream wetland were constructed <br /> to maintain proof of concept analysis for one train and have the flexibility to conduct <br /> stress tests on the second train. A schematic of the pilot-scale testing set-up is shown in <br /> Figure 6. <br /> Treatability Testing Report 14 December 11,2018 <br />
