This powerpoint presentation begins by presenting a brief overview of the Water Research Foundation (WRF) Project #4131,
Optimizing the Sustainability of Treatment Processes for
Nitrate 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 nitrate
removal technologies;
to identify co-contaminant treatment;
to evaluate ongoing ion-exchange pilot performance
based on same criteria;
to identify environmental issues for each technology;
to develop cost comparison; and, to
evaluate biological and ion-exchange systems based
on criteria including the triple bottom line (TBL) of
sustainability. Biological treatment technologies are presented, along with water quality characterization, pilot processes, Train 1 - MBfR, Train 2 - Upflow Bioreactor with
Plastic Media, Train 3 - Upflow Granular Activated Carbon (GAC) Bioreactor, ozone skid, and post filtration (biologically active carbon). Denitrification water quality
objectives are listed, along with the results of post-treatment performance
based on typical bioreactor effluent turbidity of less than or
equal to 1 NTU. Includes figures.
