Title: Wedeco UV System Becomes Cornerstone of Treatment for Wastewater Plant in Carmel, Indiana

The Indiana Department of Environmental Management mandated the removal of chlorine from treated effluent before release in the White River, the receptor for discharges from Carmel and other municipal WWTPs. The Carmel utility upgraded to a 36.0 mgd, Wedeco ultraviolet disinfection system. The Carmel utility considered three UV system manufacturers, conducting plant and factory tours and rated each system on a matrix. The resulting score favored the WEDECO UV system. The system is equipped with an automatic cleaning feature that keeps the quartz sleeves crystal clear and sustains pathogen kill. Using the previous chemical disinfection, the plant typically could achieve E. coli readings ranging from 100 to 235 cfu per 100 ml. By comparison, the UV system during the past disinfection season normally achieved single-digit readings and a high of 54 cfu per 100 ml, all well below the state's 235 E. coli maximum. The UV disinfection offered economic benefits and complies with the city commitment to implement green initiatives.
