Case Study: Fairplay, CO

The Fairplay Sanitation District was challenged in meeting their ammonia permit limits and wanted a process that would produce a stable effluent in a small footprint. Influent water temperatures were regularly recorded in between 6°C and 10°C. Due to these cold temperatures, nitrification was not being achieved on a consistent basis. Additionally, the District had to factor in the issue of the groundwater table rising and falling as well as the alkalinity of the wastewater that is needed for nitrification.
