While the Water Reclamation Facility in Bozeman found the chemistry worked, the logistics of transporting the liquid brewery waste there are too expensive for now. If regulations get stricter, the plant may consider this approach in the future.
So did they save $1M using this approach, or are they not even using it after all?

I grimaced at the mere thought of what kind of beer my municipality would provide.
No downsides.
Imagine having to pay a municipal tax to get Bud Light piped into your house. Ugh.
Like on large German navy ships in the first half of 20th century.
Bozeman, MT but is not currently using the process, as you noted.
"We know the alum that we saved already is about $16,000 a year for sure. But if that wouldn't have done it, that's when an upgrade around the corner would have been, and then if we have to do an upgrade, there's where you run into the millions," Newfield says.
Using the grain definitely saved them $16,000 a year in using alum, which may not have been as effective. If the alum hadn't worked, then they would have had to make the $1million investment.
"But it may not work everywhere."
However it hasn’t actually saved $1M, only saved a small amount over the alum that probably would have otherwise saved them from the $1M upgrade :)
