Centrisys/CNP is collaborating with the Milwaukee Metropolitan Sewerage District, the Metro Wastewater Reclamation District of Denver, the Madison Metropolitan Sewerage District and the Massachusetts Water Reclamation Authority to perform Tailored Collaborative Research (TCR), a program of The Water Research Foundation. The groups will work together to demonstrate phosphorus removal and recovery potential of the CalPrex process at the Madison District from September through November.

The TCR will collect high-quality data from the CalPrex process and allow the participating utilities to evaluate high-rate phosphorus recovery prior to anaerobic digestion and its positive effects on operations and maintenance. This will help the utilities better meet stringent biosolids regulations and simultaneously mitigate operations and maintenance issues related to phosphorus levels in sludge. A peer review of the findings will be conducted, and the results will be disseminated to industry professionals through The Water Research Foundation LIFT Link platform.
