LOUIS CHAPMAN MARCIA SILVA Removal of AmmonIa "Tough on grease, grime... and rivers." LOUIS CHAPMAN MARCIA SILVA
PURPOSE AND Available Methods Eutrophication Biological nitrification (waste) Anaerobic Oxidation (tanks) Chlorination (8:1 ratio) LiquiCel Membranes (Consumable)
Benefits of Ion Exchange Zero biological waste Operates in cooler climates Rechargeable Modified for targeted removal Drawback: Water Hardness
Preliminary Results
Fabrication Retest the filter to see if a drop in performance occurs Clean particle of impurities Step 1 Impregnate with metal precursor at high temperatures Step 2 Regenerate using salt solution Retest the filter to see if a drop in performance occurs Regeneration Fabrication
Column Testing Stock and Standards Reagents Adsorbent Contamination complications Stock and Standards Nessler's Reagent Vacuvials Reagents Desorb ammonia and regenerate with salt solution Adsorbent Column Testing
Conclusions This material serves as a viable alternative to nitrification due to its ability to be easily regenerated Upkeep and startup costs are low compared to traditional methods Can be modified to target specific contaminants Futher Research: Refine the modification process and regeneration process
