Water Research Foundation Tailored Collaboration # 4448 Optimizing Filter Conditions for Manganese Control During Conversion to Biofiltration North Texas Chapter TAWWA Meeting August 22, 2013 Greg Pope Gary Smith Chance Lauderdale Kara Scheitlin John Zwerneman Mary Jo Kirisits
The discussed project includes the combined efforts of multiple partners • The Water Research Foundation • Trinity River Authority (Project Sponsor) • Carollo Engineers • The University of Texas • A Project Advisory Committee includes staff from - • Virginia Tech • US EPA • University of Illinois • American Water
The presentation objectives outline project purpose Tarrant Country Water Supply Project (TCWSP) background and Mn history Remaining studies and future work Review of biological filtration enhancement strategies Evaluate Conversion to Biofiltration at TRA Emphasis on Acclimation and Manganese Removal Study summary and preliminary conclusions Media characterization and microbial Tracking Pilot-scale biofilter testing of selected enhancement strategies
Tarrant Country Water Supply Project background and Mn history
The TCWSP process includes ozonation and conventional process NaOH, Ammonia Alum Ozone Chlorine Polymer BWW Raw Water Effluent Clearwell Ozonation BW Flocculation/Sedimentation Filtration
The process will convert to biofiltration for improved T&O removal and finished water stability NaOH, Ammonia Alum Ozone Chlorine Polymer BWW Raw Water Effluent Clearwell Ozonation BW Flocculation/Sedimentation Biofiltration TRA, Carollo, and the WaterRF are seeking to optimize the conversion process in a 9-month pilot study focused on biofilter enhancement
