Problem: The city of Marengo, Illinois, faced capital costs estimated at $2.1 million to repair and upgrade its aging temperature-phased anaerobic digestion process. The city sought an alternative disinfection and stabilization process.

Solution: The city commissioned a CleanB system from BCR Environmental.

Result: The process consistently met Class B disinfection and vector attraction reduction requirements and significantly reduced repair, maintenance, energy and polymer costs, while also reducing odors. In addition, with reduction in nutrient return from digestion, effluent nutrient concentrations continue to decline. The system will enable the city to outperform regulatory requirements for biosolids and effluent. 866-724-9145; www.bcrinc.com/resources
