Solution Provides Biogas to Power Ken's Foods Plant

[Fledermaus]

Expansion, a solution for problematic high-strength organic content wastewater, and a power source bonus—that's what Ken's Foods' plant in Marlborough, Mass., got when it upgraded its wastewater treatment facility with an ADI-AnMBR (anaerobic membrane bioreactor).

The anaerobic treatment technology uses submerged membranes for biomass retention and solids-liquid separation. The system maximizes biogas production and increases solids digestion while handling the large-volume food manufacturer's wastewater, which has a high content of fats, oil, and grease (FOG). The company converted its existing low-rate anaerobic reactor to operate as the reactor portion of the new AnMBR. The combined system produces 200,000 to 300,000 cubic feet of biogas per day. This captured byproduct provides 100 percent of the wastewater treatment plant's heating requirements as well as enough residual biogas to power more than 50 percent of the company's manufacturing facility.
