Shawano County, Wisconsin
The Caroline Sanitary District’s existing effluent quality could not consistently meet
the present requirements. The Caroline Sanitary District decided to treat the effluent to
lower the effluent pH rather than utilize other processes to reduce the ammonia nitrogen concentration. This project included installing a fine bubble aeration system in existing lagoon cells and a carbon dioxide feed system to control effluent pH.
