As demonstrated with the wastewater pretreatment facility design for Link Snacks, Inc. in Alpena, SD, Banner has the capability to address high strength industrial wastewater treatment. Previously the industry's waste was pretreated with a dissolved air flotation process and then sent to the City's anaerobic lagoons and retention ponds several miles out of town. However, issues with the pond process and the industry's growth necessitated additional pretreatment closer to the source of the wastewater. Link Snacks, Inc. sought out Banner's experienced staff to evaluate five aerobic and anaerobic treatment process. Based on an life cycle cost and performance analysis, an anaerobic membrane bioreactor (AnMBR) was recommended for the industry's high strength waste. The AnMBR is operational and is achieving the required reductions in BOD5 and TSS concentrations for this process. The AnMBR process is followed by an activated sludge/final clarification process for nitrification and hydrogen sulfide reduction. Nitrogen and phosphorus removal will be achieved with the future addition of an anoxic tank. A belt filter press is also provided for solids handling.
