Ken’s Foods Utilizes Anaerobic Membrane Bioreactor to Generate Biogas to Power Wastewater Treatment Plant Operation
Although all food processors have to deal with wastewater generated in their operations, the characteristics of the effluent exiting their facilities can vary greatly, requiring different processing technologies for the most efficient handling of the wastewater.
Ken’s Foods of Marlborough, Massachusetts, a large-volume food manufacturer of salad dressings and marinades, recently upgraded one of its three wastewater treatment facilities to more efficiently process its high-strength organic content wastewater, effluents which contain a high content of fat, oil and grease (FOG) and present serious challenges for waste treatment.
The solution incorporated a unique treatment process called ADI-AnMBR (anaerobic membrane bioreactor), a relatively new form or anaerobic treatment technology developed by ADI Systems, Inc. (ADI) in cooperation with Kubota Corporation of Japan, that utilizes submerged membranes for biomass retention and solids-liquid separation.
The system maximizes biogas production, increases solids digestion and provides a means to easily handle wastewaters with high concentrations of organic matter.
