The Merrill Wastewater Treatment Facility is a small municipal plant in Merrill, Wisconsin, serving the environmental services sector. Its evolution began in the early 1950s, with notable upgrades in the 1970s and again in the late 1980s to early 1990s, and it is currently conducting a full-scale pilot of biological phosphorus removal. The plant operates a conventional activated sludge process that provides primary settling and biological secondary treatment, routing primary and waste activated sludge to anaerobic digesters for digestion and stabilization.
