Aerator retrofit enables city to meet nitrogen limits - Case Study
The City of Ocala, Fla., faced tighter effluent nitrogen limits due to the presence of springs in the St. John’s River basin. The city operates an Ovivo Carrousel plant.
Rather than add basins, the city retrofitted the Carrousel basins with dual-impeller Excell aerators and the automated internal recycle EliminatIR gate from Ovivo USA.
The retrofits have allowed the city to more tightly control dissolved oxygen and nitrate recycles and reduce total nitrogen to near the limits of technology.
