AG WEB, Journal (1/7/16) -- A Wisconsin researcher, Phillip Barak from the University of Wisconsin at Madison, has been looking into how to remove phosphorus from biosolids. Barack’s solution is to remove phosphorus from biosolids in the form of brushite, a calcium phosphate mineral. The research team completed their firsts pilot of the phosphorus recovery process at a wastewater treatment plant in the Chicago area. As the business develops the group will work with wastewater treatment plants, selling their phosphorus removal process and with farmers to sell the recovered phosphorus.
