I've read previous posts on this issue but I need some help with details for a meeting with the ministry of environment here. Does anybody have a cleaning & sanitizing plan that they used for local authorities to convince them that they will not be trashing the local sewage plant? We're talking about a 10 bbl micro with 3 10 bbl fermenters and a bunch of grundies (6) for conditioning tanks. All tanks are CIP. I've managed to convince them that spent grains/trub/yeast are going to the cows so it's really just the cleaning side they're concerned with.
Some of the details they've been asking about:
1. How often are tanks cleaned
2. How often are the tanks sanitized
3. How much water is used in cleaning/sanitizing process
4. What chemicals are used in cleaning/sanitizing and in what dilutions
5. What will be the PH of the caustic & acid solutions when sewered. I've told them I'll be reservoiring & recycling the solutions so the real question is until what PH is the caustic and the acid effective?
6. What special equipment do I need to recycle caustic & acid solutions & is it worth it?
Anything else you can think of that would be of interest to a sewage plant would be extremely helpful.
Thanks.
