Holly Gray successful thesis defense
On April 25 Holly Gray successfully defended her MSc research "Phosphorus Speciation, Dissolved Organic Matter and Surface Characterization of Wastewater and Implications for Phosphorus Removal across a Range of Treatment Technologies". In this research Holly demonstrates that phosphorus within humic and fulvic acids might represent the most difficult to remove fraction of total phosphorus in waste water. Holly also demonstrated some advanced oxidation techniques with potential to treat refractory organic phosphorus in wastewater treatment. Finally Holly revised pH prediction methods to include solid phases. This method would be required for high solid systems such as often occur in wastewater streams.
