Barak, 2015

Of current interest:
My current research activities relate to nutrient recovery from wastewater, including phosphorus removal from wastewater treatment plants in the form of brushite, a largely neglected phosphorus fertilizer. Coverage of this activity is to be found at: 'UW helps communities create cleaner, greener wastewater', Second Life for Phosphorus', 'Second Life for Phosphorus - Interview', 'Business will implement new phosphorus recycling process in Midwest' and 'New Solution Reduces Phosphorus Pollution and Helps Farmers'.
My most recent push is for nitrogen and potassium recovery from anaerobic digests of various kinds by electrodialysis. Because these projects have an applied and commercial aspect to them, I have worked closely with WARF, the intellectual property holder of the Univ of Wisconsin-Madison, and the campus Conflict of Interest Cmte; Nutrient Recovery & Upcycling (NRU), LLC, has been set up to patent and commercialize intellectual property from the Barak Lab.

Research interests:

My background is in soil chemistry of plant nutrients, plant nutrition, and scientific visualization. My current interest is largely nutrient recovery from wastewater, particularly P, N and K, and this is the thrust of my current research projects. Previous projects include:
