Rolling A WWTF

Rolling A WWTF in the Dayton area holds the permit #NEV200500. This is a SBR (Sequencing Batch Reactor) designed by ABJ Group Sanitaire. This system is an ICEAS (Intermittent Cycle Extended Aeration System). The plant initiated operations in the last quarter of 2000 with a permitted flow of 0.058 MGD. At that time there was only a storage pond for the wastewater. That phase handled the flows for 2 years. The plant is now permitted for 1.5 Million gallons per day. The plant is permitted to treat to the limits in the table below.
