Constructed wetlands have been used for decades to successfully treat various industrial and municipal wastewaters. Wetlands generally consist of shallow basins through which water flows and contacts wetland flora, soil, and microorganisms. By controlling water flow and using appropriate plants and soils, natural processes are enhanced to efficiently clean the wastewater. Constructed wetlands have a proven track record for addressing biochemical oxygen demand (BOD), solids, and pH in wastewater from operations such as breweries. Constructed wetlands typically produce no additional waste streams, are robust and generally easy to construct, and seldom require chemicals. In addition to being less expensive to operate and maintain than traditional wastewater treatment systems, constructed wetlands are an environmentally sustainable treatment method that can be an attractive focal point for a brewery that showcases green technology. A pilot-scale constructed wetlands system was constructed at Holy City Brewing in Charleston, South Carolina, to provide proof of concept and a basis for full-scale wetland design. Results and lessons learned from the pilot study will be presented. Properly designed constructed wetlands for brewery wastewater treatment can provide a solution that is economically feasible, socially acceptable, and environmentally sustainable.
