Although St. Francis, Minnesota, located in Anoka and Isanti counties, has a population of only 7,218, it has big ideas when it comes to the future of its wastewater treatment system. Those big ideas came to fruition starting in 2015 when the city began building a new treatment facility at its existing wastewater treatment plant, which was built in the 1970s. Although upgraded in 2000, the upgrade did not address existing and future regulations regarding ammonia and phosphorus.

Howard County, Maryland, has taken a leading role in restoring the Chesapeake Bay ecosystem through a $92 million upgrade to its wastewater treatment infrastructure. Central to this effort is the installation of Xylem’s Leopold elimi-NITE® 2.0 denitrification system, which significantly reduces nitrogen and phosphorus levels in effluent discharge. Combined with advanced UV disinfection and mixing technologies, the system's daily reductions include 37,000 pounds of suspended solids, helping to reverse decades of nutrient pollution and protect aquatic life in the Bay.

In search for the best wastewater treatment process in terms of removal of microbiological contaminants and the abatement of bromate discharge, RWTH Aachen University, along with the other environmental institutions, launched a research project and partnered with Xylem to test the effects of wastewater ozonation on water quality and its ecosystem.
