Wastewater treatment is a key issue for a craft brewery. John Mercer from Brewery Wastewater Design in Montrose, Colorado has more than a decade of experience. He shares wastewater treatment solutions for a craft brewery.
For every gallon of beer produced, a typical brewery uses 7 gallons of water. If your municipal wastewater treatment plant can’t handle it, you could be facing high fees for wastewater treatment.
Brewery wastewater can fall into one of several categories:
- Floor drains in the brewery, which contain alcohol, sugars, and other contaminants.
- Kitchen drains, which includes grease.
- Restrooms, which typically go the sewage treatment plant.
- Side stream, which is a way to divert extremely concentrated wastewater such as spent yeast, waste beer, fermenter blow-off, and trub.
If your brewery is in an area that has municipal sewage service, you might not have to do anything. If you’re in the county with no sewage service, you’ll likely have to build your own brewery wastewater treatment infrastructure.
Solutions will vary depending on your brewery wastewater characteristics, or who designs your system.
Diverting the very concentrated sources through a “side stream,” could reduce the contaminants in your wastewater by 90%. Which could mean reduced fees for treatment.
Key questions to ask:
- Is the wastewater facility at capacity?
- How much would the fees cost?
- Does your consultant have experience designing systems for breweries or other food manufacturers?
