U.S. EPA releases Phosphorus Removal Technology Study

“Six Municipalities, One Watershed: A Collaborative Approach to Remove Phosphorus in the Assabet River Watershed” was released by EPA in March 2015.  Four Water Resource Recovery Facilities (WRRFs) that serve six municipalities selected and provided feedback on the use of four different phosphorus removal technologies., which was implemented with other facility improvements. The portion of the upgrade costs due to phosphorus removal improvements is difficult to separate from the total cost and can vary significantly based on how the costs are allocated. The estimated cost of the WRRF upgrades ranged from $4 to $25 million.
