Wastewater Management

[Bud Desmul]

We have to come up with a wastewater management plan for our county sanitation officer and DEQ as a condition of licensing. Does anyone have any numbers regarding the volume of wastewater generated per volume of cider produced? There is data available (with wide ranges) for the winery and beer industry but the processes are different and I suspect the water use is lower for cider. If you have estimates for BOD and COD then so much the better.

Thanks

I have nothing to add, but I would also be very interested to hear more about the scale and process employed by those that respond to this question.  Do you use tanks/totes/barrels?  How do you clean and sanitize?  Do you press your own fruit and deal with that waste stream as well?  Thanks.

Trying to get necessary permissions myself. I don't think it is possible to get accurate figures for your wastewater without actually having generated it! Even for the wine industry (most similar to cider) for which figures are available, the ranges are very wide (too wide to be useful in designing a wastewater treatment system). The wide range is expected I think, since different manufacturers use very different processes (both chemically and mechanically). Further, there will undoubtedly be wide swings (both in volume as well as specification of wastewater) since at different times of the year a cidery would be engaged in very different activities.

 

What I finally settled on was getting a treatment plant (design attached) with much higher capacity of 2000 L/day. Surprisingly, the price difference is really negligible if one goes in for smaller capacity units (I think the holding tank size is really what differs at lower capacities). I estimated/submitted an average daily production of 250 liters of wastewater (150L/day industrial and 100L/day domestic) for an annual production of 15,000 litres of cider. This leaves me plenty of margin to deal with any seasonal fluctuations as well as to dilute my wastewater in case of very high oxygen demand.

Unfortunately, this is all still in theory for me!

For 15000 litre cider roughly you will generate 1000 litre waste water including sanitisation and rinsing of your fermentation tanks. But it will depends on you whether you will do it one time fermentation or in batches. If you will go for batches then it will multiple of it.

Industry standard for white wine (most similar to cider) is for annual water usage to be 4x of annual production.  Other wineries (red wine, with lots of barrels) is up to 12x.

We use 1x, for all uses, including pressline cleaning.   We are very miserly with our water.

Check the book Winery Utilities.   Lots of good info in there and worth the $ if you are building a facility.
