Equalization and flow buffering

Brewery wastewater

Is your brewery in a small town, or are you looking at opening one there? Here are some considerations to think about.

The local wastewater plant sees most flow during the day; flow peaks in the AM as people shower and make breakfast. Flow decrease mid morning, has a little peak around lunch time, goes down, and peaks again as people get home from work. Then flow really dives down overnight as people go to sleep. This isn’t a hard a fast rule, but generally speaking this happens everywhere. Half time of the Super Bowl is a classic spike in flow:) ¬†Industry in town can change these spikes, as well as rain, snow melt, or who knows that else.

Anyway, that lull in flow overnight can be a big benefit to a brewery. If the city is telling you they are at capacity at the wastewater plant, you could store the brewery wastewater all day and discharge it at night. This helps keep loading at the treatment plant flat throughout the day (good for them) and solves the capacity issue at least for a few years.

Similarly, if your brewery is only running 3-5 days a week, you could store the wastewater and slowly meter it in to the sewer 24/7. Again, this helps flatten the loading at the treatment plant, which the wastewater operators love. What those operators do not want to see is bigger peaks and valleys in load at the treatment plant.

Let me know if you would like more information on any of this. Cheers!
