Phosphorus Recovery From Beef Feedlot Wastewater Using the Phred™ System.

Recent promulgation of federal and some state regulations has created a potential market for technology capable of reducing the phosphorus in livestock and poultry manure.  With a focus on commercialization Kansas Environmental Management Associates, LLC led the research and development of a full-scale treatment system to remove dissolved phosphorus from livestock waste by forming struvite.  The system has been successful at significantly reducing the land needed for application of livestock waste, while producing a granular struvite-based product.  The struvite has been tested successfully in agriculture and horticulture applications, and has shown itself to be an effective fertilizer.  There are however many obstacles to the adoption of this technology, including regulatory uncertainty, slow moving alternatives, cost, and consumer resistance to new technology.
