Nov 30, 2018

DENVER, CO – The Water Research Foundation (WRF) has launched a project, Demonstrating the CalPrex™ System for High Efficiency Phosphorus Recovery (5004), between the Milwaukee Metropolitan Sewerage District (Milwaukee, Wisconsin), Madison Metropolitan Sewerage District (Madison, Wisconsin), Metro Wastewater Reclamation District (Denver, Colorado), Massachusetts Water Resources Authority (Boston, Massachusetts), and Centrisys/CNP (Kenosha, Wisconsin), to demonstrate a high-rate, pre-digestion phosphorus removal and recovery technology. The technology, developed at the University of WisconsinMadison and licensed from Nutrient Recovery and Upcycling (NRU) by Centrisys/CNP under the name CalPrex™, ran as a ~10 gallon per minute pilot system from October through the end of November 2018 at the Madison Metropolitan Sewerage District. The demonstration has provided high-quality data that will allow utilities to evaluate high-rate phosphorus recovery and its effects on phosphorus load management.
