We have our production in the facilities of a quite big brewery that closed down 15 years ago.
We have excellent drains. Up to 16 inch 316l stainless that was left when the other brewery closed down.
The drains, however, are corrected to a neutrilization basin. I don'ẗ know the english word for it.
It is two basins of around 10 million liters put together where the pH is to be equalized to 6,5-10.0 before being pumped off to to the citys main sewer lines.
10 million liters is of course vaslty above what we really need, but the level switches now starts the pumps at the lowest possible setting wich is 75-140 000 liters. Don't know the precise number.
Six months back, we began experiencing severe infections down there. Think outhouse, that has been used by very many people during a hot summer.
So, the basins where emptied and cleaned for the first time since the 90s. My guess is that it would help with the pH problems we have been having. At least for a little while.
The problem to me is obvious. The basins are far to big for us, so we don't have enough circulation through the basins to wash out bacteria and neutralize the acid environment before it gets lowered again by bacteria.
One of the basins are to be bypassed so we only use one. But what if the problem remains?
Is the only solution to have a couple of tons of pure caustic in storage at all times and adjust when needed?
I estimate that we pour down 50 000 liters each week.
Our contract says we are to have access to a functioning drainage system and I really doubt this is our fault. I think we are just pouring down nutrients for the bacteria. Current pH levels are 4,5.
