Study: Reactors can stop phosphorus formation

In a recent study, engineers at the University of British Columbia’s Okanagan campus developed guidelines that can tailor the design of specialized filters, called fluidized bed reactors, to local conditions and help prevent phosphorus deposits from forming in wastewater systems. The guidelines also help ensure the fluidized bed reactors avoid the release of phosphorus into the environment.
