Preparing Water For Discharge Into The Great Miami River

Per capita, Sidney has the greatest number of manufacturing jobs in Ohio. As a result, its WWTP receives a significant portion of its flow and loading from local industrial facilities. To ensure the plant could continue to effectively meet its current and future treatment objectives, an improvement project was initiated to increase treatment capacity, bolster reliability and improve safety at the plant. The plan included upgrades to increase design capacity to 7.5 MGD and peak capacity to 14 MGD. In addition, a conversion from chlorine to UV for final disinfection would be implemented. After the completion of the plant’s improvement project, the treatment process would consist of primary clarification, biological treatment, secondary clarification, UV disinfection, and post treatment aeration.

In this case study, discover how the WWTP used a Mazzei aeration system to continue meeting its permit requirements without adding to the daily responsibilities of plant personnel.
