Food Processor Uses ADI® Anaerobic Membrane Bioreactor (AnMBR) System to Once Again Treat High-Strength, High-Solids Wastewater

摘要

Ken's Foods is a food manufacturer that produces salad dressings, sauces, and marinades. It generates a high-strength industrial wastewater with high concentrations of organics, suspended solids, and fat, oil, and grease (FOG). An ADI® anaerobic membrane bioreactor (AnMBR) treatment system was installed at Ken's Foods Marlborough, MA, USA, plant in 2008 and operated successfully for nearly ten years. The AnMBR technology is an innovative approach that allows Ken's Foods to maximize plant production, decommission tanks and equipment from its existing treatment plant, ensure final effluent complies with municipal discharge requirements, and generate a green energy source from its wastewater. The operating experience gained at the Marlborough plant gave Ken's Foods confidence that the AnMBR technology would also work for other plants. In 2017, Ken's Foods once again selected Evoqua's ADI Systems, an Evoqua brand, to design and install an AnMBR system for its McDonough, GA, USA, plant to treat the raw processing wastewater. This paper will review the design and construction of the AnMBR system, outline how the treatment plant overcame the challenges associated with treating high-strength industrial wastewater, highlight the first few months of system operation and performance, and discuss how the AnMBR was incorporated into the existing operating treatment plant without disrupting system operation.
