Having grown up in the area, I'm very familiar with the green algae growth faciltiies in Central Wisconsin, otherwise known as Petenwell Lake and Castle Rock Lake. So I found this video clip to be particularly interesting - they're using green algae to remove phosphorous. It makes sense to me - the phosphorous is used by the algae, which uses it as a nutrient to grow. The effluent water is then more phosphorous-free, and you remove the algae as it grows too big. That's my take on it anyway - watch the video and see what you think.
"New York is testing out a new water scrubber at one of its wastewater treatment plants in Queens. Meet the algal turf scrubber--two 350-foot slides covered in green algae. Water flows down the slides, algae grows naturally, and then helps clean water that is sent over it. John McLaughlin, Director of Ecological Services for the New York City Department of Environmental Protection (DEP), and Peter May, restoration ecologist for Biohabitats, explain how the scrubber works, and where the harvested algae goes."

What about you? It seems like the phosphorous rules in Wisconsin are actually going to happen (as of right now, anyway), so how are you planning to deal with the change? Comment below!
