“So it’s kind of a double benefit: One, we clean up our wastewater and, two, out of that cleanup we are able to make energy for ourselves.” “Then we are going to generate energy for 35 or 40 percent of the electrical operations here at the brewery,” he says.

Matt expects it will take a couple months before the digesters are producing enough gas to run their 400 kW generator at full capacity. 1 through May 31.īecause Matt Brewing is a significant industrial user, they had a discharge permit with the county that needed to be modified to include the digesters. It must treat a minimum of 48 mgd from June 1 through Oct.

“It will ultimately reduce the loading to our treatment plant and reduce the cost of wastewater disposal for Matt Brewing.” A discharge permit from the state Department of Environmental Conservation sets the treatment limits for the plant.

“I think it’s a very progressive idea for Matt Brewing to install this system,” says Steve Devan, commissioner of the Oneida County Department of Water Quality and Water Pollution Control. The volume discharged will actually remain the same, but by removing 80 percent of the organic content, it will put less strain on this older community’s sewer system. “We use an average of 150,000 gallons of water per day, so we are going to take a pretty big load off of the municipal sewer system.” “The net effect from all of this is that we estimate we are going to clean up our brewery’s wastewater by 80 percent,” states Matt. “EMG and Matt Brewing personnel will be able to continually observe and modify the system’s operation remotely.” “The digester system is operated using a SCADA unit with remote-access capability,” says Manaf Farhan, president of EMG International.

EMG will also continue to oversee the operation. The digester system will be operated by personnel at Matt Brewing, who are being trained by EMG International. In effect, we clean those out and then make methane gas.” What we’re doing in the anaerobic digester tanks is using bacteria to eat up the leftover alcohol, sugars and other organics that are left in the water. “What happens in the digester tanks is, on some levels, very parallel to what happens when we make beer,” explains Matt, “where you put in yeast and use the sugar in the beer to make alcohol and carbon dioxide. Organics in the digester tanks are treated by a mixture of anaerobic bacteria - including acidogenic and methanogenic organisms - that create biogas composed of methane gas and carbon dioxide. The 40,000-gallon digester tanks can be operated in parallel or in a series. The wastewater is pumped from the equalization tank to five anaerobic digester tanks, located 50 to 150 feet away. The equalization tank normalizes the flow and preconditions the wastewater before entering the digester units. Rather than going to the municipal treatment plant, the wastewater now goes into an onsite 200,000-gallon equalization tank. When the various vats and tanks in the brewery are cleaned, beer residue, yeast, residual wort from the brew kettles and other solids previously ended up in the Oneida County Water Pollution Control Plant. The company is making final adjustments, while the bacteria at the heart of this process are seeded and begin to do their work. The equipment, designed and fabricated by EMG International, based in Media, Pa., has been installed. The project, which will cost upwards of $5 million, is now in the startup phase.
