MSU prof helps devise method of removing phosphorous from wastewater

 
A professor at Michigan State University is part of a team developing a new method of removing phosphorous from our wastewater – a problem seriously affecting lakes and streams across the country.
In addition, Steven Safferman, an associate professor of biosystems and agricultural engineering, and colleagues at Columbus, Ohio, based-MetaMateria Technologies, are devising a cost-effective way of recovering the phosphorous, which then can be reused for fertilizer products.
Although its use is regulated in many states, including Michigan, in items such as detergents and fertilizer, phosphorous is part of all food and remains a critical problem as it is always present in human and animal wastes.
Discharge from human and industrial wastewater and runoff into lakes and streams can cause what is known as eutrophication – making the water unsuitable for recreational purposes and reducing fish populations – as well as causing the growth of toxic algae.
What MetaMateria Technologies and Safferman have figured out and tested over the past 10 years is how to produce a media, enhanced with nanoparticles composed of iron, that can more efficiently remove larger amounts of phosphorous from water.
