2. 2 Presentation Outline n Background experience n Research and results n Conclusions and practical implications n Equipment derived from research n Background experience n Research and results n Conclusions and practical implications n Equipment derived from research 20011011-2

3. 3 Background Experience n 1991-1992, U.S. EPA Superfund Innovative Technology (SITE) Program n 1993, Environment Canada Contaminated Sediment Treatment Technology Program (CoSTTeP) 20011011-3

4. 4 Practical Problem n Surfactant washing can effectively clean organic contamination in larger soil particles HOWEVER n Low energy mixing with chemicals has little effect on contaminated sediments 20011011-4

5. 5 Research Questions n What are the limitations of solvent extraction? n What is the role of biomass in absorbing organic and inorganic contamination? n How do chemicals, impact pressure, and impact surface affect removal efficiencies? n What are the limitations of solvent extraction? n What is the role of biomass in absorbing organic and inorganic contamination? n How do chemicals, impact pressure, and impact surface affect removal efficiencies? 20011011-5

6. 6 Experiments n Use standardized mixtures of sand, silt, and clay n Investigate the role of biomass in absorbing contamination n Test both organic and inorganic contaminants n Determine the effect of physical impact in desorbing contaminants 20011011-6

7. 7 Chemicals Extract Organic Biomass & Contaminants 20011011-7

8. 8 Biomass Absorbs Organic Contaminants 20011011-8

9. 9 Lead Contamination Migrates to Organic Fraction 20011011-9

10. 10 Chemicals, Pressure Increase Extraction Efficiency 20011011-10

11. 11 Experimental Conclusions n Higher contamination is on the smaller particles n Chemical means should be combined with physical means for best results n Effective cleaning requires separating biomass from the solid phase 20011011-11

12. 12 Resulting Equipment: Preprocessor n Exposes solid particles to chemical and physical forces n Separates organic material from solids 20011011-12

13. 13 Resulting Equipment: Collision Chamber n Cleans organic and inorganic contaminants from solids using impact force 20011011-13
