Problem: A midwestern municipal sewerage district faced significant issues with its acid-phase steam injector units, including frequent plugging, high labor, and parts costs, and disruptions to the digestion process. District staff sought to reduce downtime and operating costs.
Solution: Hydro-Thermal developed an unrestricted flow solution called the Non-Obstructive Heater, allowing larger solids to pass through without causing blockages. The units fit the original footprint with minimal piping modifications.Result: The system significantly reduced plugging and emergency work orders while optimizing the acid digestion process. This reduced labor and maintenance costs. Without the project, plugging would have continued. The Hydro-Thermal NOH improved digester
