This powerpoint presentation begins by presenting a brief overview of the Water Research Foundation (WRF) Project #4131,Optimizing the Sustainability of Treatment Processes forNitrate Removal in Inland Communities". A brief overview of nitrate contaminated groundwater is presented, along with Glendale, Arizona's water system and its groundwater master plan. Project objectives were:to characterize the performance of biological nitrateremoval technologies;to identify co-contaminant treatment;to evaluate ongoing ion-exchange pilot performancebased on same criteria;to identify environmental issues for each technology;to develop cost comparison; and, toevaluate biological and ion-exchange systems basedon criteria including the triple bottom line (TBL) ofsustainability. Biological treatment technologies are presented, along with water quality characterization, pilot processes, Train 1 - MBfR, Train 2 - Upflow Bioreactor withPlastic Media, Train 3 - Upflow Granular Activated Carbon (GAC) Bioreactor, ozone skid, and post filtration (biologically active carbon). Denitrification water qualityobjectives are listed, along with the results of post-treatment performance based on typical bioreactor effluent turbidity of less than orequal to 1 NTU. Includes figures.
