Driven by a passion for innovation, the Kenosha Wastewater Treatment Plant team has converted a messy, inefficient biosolids process into a state-of-the-art resource recovery and energy production system.The technology includes thickening centrifuges; thermal-chemical hydrolysis; high-solids anaerobic digestion with mechanical hydraulic mixing; biogas conditioning, dewatering and drying; and combined heat and power generation. The system has been humming along for just under two years, generating all the electricity and heat required for biosolids handling, and surplus electricity for about one-third of other treatment plant needs.Humming is the right word. It’s clean and quiet as Curt Czarnecki, director of engineering services, shows
