Was anything ever true at Phoslock, page-32

I gathered that this is the Wisconsin list of towns and cities that are due for upgrade of waste water facilities under funding from the Clean Water legislation.
If you highlight the term phosphorus within it you get around 40 hits with a value of projects around 80-100 million. Eg Walworth County MSD upgrade for WWTP Phosphorus compliance 12.5million.
That Phosflow is trialing, as per chand's find, with a Wisconsin Wastewater Treatment Plant is about as exciting as sewerage gets.
