  1. Absorbtionof Sulfamethoxazole an Organic Pollutant By: Juan Martinez

  2. Background • Raised in Texas • Pearsall High School • College Credit • Summer Prep • Track • Basketball • Texas A&M University Kingsville • Basketball • Track • AAEE

  3. Motivation The summer pre freshmen engineering program (PREP) molded my brain and in my 4th year the focus of the program was water management and treatment. PREP took the 4th year students on a tour to San Antonio Water Systems (SAWS) we saw the water management and treatment systems.

  4. Objective • The research objective was to remove pharmaceuticals from waste water and storm water. • The removal of pharmaceuticals would protect fish populations and prevent undetermined long term health effects on humans

  5. Need for a low-cost sorbent • Wastewater emerging contaminants • Pharmaceuticals and personal care products • Indirect water reuse • Improve drinking water source quality • Remove natural organic matter (NOM) • DBP precursors Increasing loads of synthetic organics, such as pesticides in developing countries

  6. adsorption • So there is a need for removal but there is still yet a demand to remove these compounds • Sulfamethoxazole was used in the study • It is used to treat urinary tract infections • Removal of compounds by adsorption to a solid material (adsorbent) • Bio Chars can become to answer to a problem that we know about, but refuse to look at.

  7. Important Materials • Chars • Bio solids (BS) • Forced Draft Pine (FD) • Natural Draft Pine (ND) • Powder Activated Carbon (PAC) • Eucalyptus Low Temperature (LOW) • Waters • Big Elk Meadow (BEM) • Deionized (DI) • Stormwater (SW) • Waste Water (WW)

  9. Procedure • Muffled Glass and Filters • 500 degrees C • 3 hours for Glass • 2 hours for filters

  10. Procedure • Jar tester • Initial speed 250 RPM for 1 min • Constant Speed 70 RPM • Test times • 10min • 30min • 60min

  11. Procedure

  12. Procedure • 4 ml of treated water • 2 pumps of the cocktail set to 8ml • Cocktail • Solvent • Surfactant • Fluors or Scintillators

  13. Results • BEM Ranking • PAC • FD • BS • ND • LOW • DI Ranking • PAC • FD • BS • ND • Low

  18. Results Storm Water

  19. Results Storm Water

  20. Results Storm Water

  21. Conclusion PAC was the best performing char used but there is still data proving other options are available The experiment has room for improvement and expansion Future test many look at the other chars not searched here Future test may have a mixture of chars The field of biochar had the potential to solve the growing issue with pharmaceuticals in the water
