The Water Research Foundation launches tailored collaborative research demonstration of CalPrex high efficiency phosphorus recovery

Centrisys/CNP, located in Kenosha, Wisconsin, is collaboratively working with the Milwaukee Metropolitan Sewerage District (Milwaukee, Wisconsin), the Metro Wastewater Reclamation District of Denver (Denver, Colorado), the Madison Metropolitan Sewerage District (Madison, Wisconsin) and the Massachusetts Water Reclamation Authority (Boston, Massachusetts).

Together, they will perform Tailored Collaborative Research (TCR), a program of The Water Research Foundation (WRF), to demonstrate phosphorus removal and recovery potential of the CalPrex process at the Madison Metropolitan Sewerage District from September to 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 WRF LIFT Link platform.

Phosphorus (P) removal and recovery is one of the hottest topics in the wastewater biosolids industry today. Tightening regulations for both land applications and the sale of biosolids have water reclamation professionals eager to evaluate technologies that remove nuisance phosphorus from biosolids in a cost-effective and sustainable manner.
