Ken’s Foods, a producer of dressings and sauces, selected an anaerobic membrane bioreactor (AnMBR) treatment system for its food processing facility in Lebanon, Ind.
The system, from Evoqua Water Technologies’ ADI Systems, will include a 2.2-million gal anaerobic, continuously stirred-tank reactor; two 90,000-gal anaerobic membrane tanks; and a biogas collection, transmission and flare system. It is designed to produce a final effluent with low chemical oxygen demand, biochemical oxygen demand, suspended solids and fat, oil and grease concentrations in a single anaerobic process step.
The AnMBR system combines anaerobic digestion with physical separation membranes, resulting in maximum biodegradable organic removal and biogas production. Ken’s Foods has implemented the system with success at processing facilities in Marlborough, Mass., and McDonough, Ga.
