  1. BioGenesis Washing TechnologyPractical Application of ResearchInternational Conference on Remediation of Contaminated SedimentsVenezia, Italy - 11 October 2001 SM BioGenesis Enterprises, Inc. 20011011-1

  2. PresentationOutline • Background experience • Research and results • Conclusions and practical implications • Equipment derived from research 20011011-2

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

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

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

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

  7. Chemicals Extract Organic Biomass & Contaminants 20011011-7

  8. Biomass Absorbs Organic Contaminants 20011011-8

  9. Lead Contamination Migrates to Organic Fraction 20011011-9

  10. Chemicals, Pressure Increase Extraction Efficiency 20011011-10

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

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

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

  14. Resulting Process 20011011-14

  16. Field Validation of Research • Pilot project in New York/New Jersey harbor -- U. S. EPA Region 2, U.S. Army Corps of Engineers (U.S. ACE), Brookhaven National Laboratory (BNL), 1999 -- 800 cubic yards - PAH, PCB, dioxin, metals • Full scale demonstration in Kearny, New Jersey -- State of New Jersey, Office of Maritime Resources, U.S. EPA, U.S. ACE, BNL, 2001-2002 -- 75,000 cubic yards - PAH, PCB, dioxin, metals 20011011-16

  17. Contaminated Sediments CAN Be Cleaned • Sediments are highly complex mixtures of organic and inorganic material • Experiments show that chemical and mechanical means can clean organic and inorganic contaminants • BioGenesissm chemicals and full–scale equipment implement experimental findings in a practical way 20011011-17
