•  Protein Matrix applied at headworks– 100% of influent treated – 15MGD

•  Results– 50% labor cost savings– Elimination of historical grease odor– Primaries were “the best they’ve ever

looked”



•  Improved oxygen transfer•  Balance microbial populations•  Prevent overpopulation of nocarida / M-parvicella•  Reduced foaming and improved settling

•  Use as a jetting fluid

•  Increase in methane production during anaerobic digestion

•  Mitigation of chemical burns


•  Tufts University Chemistry Department– Prof. Albert Robbat, Research Advisor– Christian Zeigler, Ph.D., researcher

•  Protein Matrix LLC– Peter Rehage, Chief Formulations Designer
