Multi-Stage Recirculating Wetland
MSR Wetlands are capable of achieving high levels of treatment for BOD, TSS, nutrients and pathogens. Multiple stages perform different treatment functions. The recycle between stages provides the alternating conditions required for advanced biological nutrient removal. Each stage is sized according to process engineering calculations. The use of multiple cells allows the system to be built in stages where required. The recycle rate can be easily adjusted to respond to phases or seasonal variability in the influent flow. Each MSR Wetland is sized to meet the discharge parameters of each location.
