Hi,
We have a building that we plan on using for our new brewhouse, the building is large enough and it fits all our space requirements, ceiling heights and easy production flow. The only major issue is that it is not situated on town sewer and water. It has an existing septic tank but we are concerned about effluent and excess water usage.
We are planning on making a waste water/effluent holding tank and then transporting this via a truck to a local lagoon that processes waste water.
Does anyone out there have any experience with this or have other ways they have dealt with this issue? We are open to any and all ideas.
We know this can be done, we just want to create an environmentally safe and cost effective solution to this problem.
Thanks in advance.

hey,

In the same boat as you guys,,,,, we are a brewery located in farm country we went with the holding tanks as well for the brewery effluent, one thing that works well for us is that we can unload the trucked waste water into local farmers manure lagoons, or spread directly on fields when the seasons are right, trade waste water space for spent grains or beer,works out well all around,,,,,

Thanks for the response. If you don't mind me asking, how large are your holding tanks? And based on that, how many times do you have to empty them? We have a similar lagoon situation, but we just trying to get an idea on storage tank size. We are a 25hl brewhouse, doing double brews a few times a week.

50 hL x 2 x 8 (good starting volume multiple for effluent) = 800 hL per week of effluent to be hauled and dumped.

What about a constructed wetland?

I would think something similar to what Mr. McKenna has said.
You would use a trap system ahead of an engineered drainfield which would definitely be oversized.
The trap would not need pumping any more often than a typical one does which is ported to sanitary sewer, such as the one we run with.
Also there are said to be bio treatments that can enhance the service interval of such. I am not up on how they perform with this type of effluent.

On this brink of having one of these installed, so can't give you much in the way of first-hand usage. However, on paper it appears to be well-suited for the brewing industry, smallish footprint, minimal maintenance, lower energy use than aerobic (less pumps, more gravity) and with a bit of attention to watching pH and yeast content (BOD) of your wastewaters input into it, can even deal possibly with your other wastes (toilet, etc.) --- depending upon local laws/regs. I know, I know UASB systems have that scary word "reactor" in them. But it's really just a large tank with an array of pipe inputs that meter your waste into what's effectively an anaerobic digestion tank you can possibly (from what I've heard we'll be doing) basically prime with (holy?) cow shit. What you'll need is the money to make it, and a bit of extra space -- but not drainfield-sized.

I'm no professional on it, but it was brought up to me like "yeah, this is how breweries do it." After checking it out, been done this way often in Europe since the 80's or so?

You're of course right, WaterEng. Respect. Sorry, didn't make clear I was speaking of a system engineered around a central treatment means of UASB. This would of course be coupled with screening and holding tanks, sand filter, carbon filter, polishing, pH adjustment, biogas arrestor, and - depending - possibly chlorine dosing. Associated pumps, etc.

Figured this might then be able to go to a (smaller) drain field if they're already talking one.

Would this get them there? Even with all the processes in the listing, my understanding is that it will be (relatively) inexpensive because a lot of it is tanks and holding time. I'm quite curious how this system could function for a small-to-mid-sized craft brewer in the US looking to do a better job before we send off to someone else to deal with our effluent.

Regs here where I'm at are different than there. That's the part I don't recall anymore about the US.
