The innovative BioMag system infuses magnetite – fine, fully oxidized, iron ore particles – into biological floc, enhancing secondary clarification. The system increases settling rates, capacity, performance and stability, and meets enhanced nutrient removal (ENR) permits. For the BBA, the BioMag system was incorporated into the existing plant providing excellent clarification performance at high clarifier loadings and lower ammonia emissions. As a result, the plant includes a 41% organic capacity increase to treat higher future influent loadings, a significantly improved sludge treatment process with cleaner, better screened biosolids, and better odor control.
During the construction process, the complexity of the project increased with record rainfalls. The success of this project was a result of the thorough evaluation of treatment options to provide the lowest capital and operational costs for the plant, while providing the best effluent quality when compared to other treatment technologies available.
“This project will provide additional treatment capacity to a growing region while discharging high quality effluent to the environment. We cannot think of anything more valuable than our local water resources and protecting them for the future,” says Ralph Stewart, Authority Manager.
