So I have been working with a brewery here in Birmingham, AL and they have been having issues with the county sewer department charging outrageous surcharges for sewer impact. I have done everything I can to prevent as much BOC and COD from entering the sewer as possible. The only remaining impact they have is of course hot side trub and spent CIP chemicals. Which according to the sewer department pushes BOD/COD, phosphates, and pH over the normal threshold. I had a solution for the spent CIP chemicals, which are suppose to be phosphate-free, by collecting them all in one tote and then blended down the pH. Of course this primarily addresses pH and not necessarily COD. A central CIP system would probably cut down on the overall amount of chemicals used but they are limited on space. As far as the hot side trub I have considered purchasing a small centrifuge to remove all the particulate before entering the sewer.
We were consulting with a company that manufactures waste water treatment systems but they have backed out on providing a solution due to some issue with their current technology. I have also read the recent article in TQ but a bio-reactor maybe a little overkill for their operation.
I have taken measurements of the amounts of all effluent from their points of impact and have came up with the following numbers. At two batches a day and five days a week, the volume of hot side trub (including rinse water) is about 1000 gallons. The volume of spent CIP chemicals produced on a weekly average is about 1550 gallons. So we're looking at about 2550 gallons of wastewater a week with a decent amount of organic particulate.*
At these volumes does anyone here have any recommendations or experience they can share to provide a solution for this issue?*
