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

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

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

  • B. Mechanical cleaning effect
  • C Area requiring more chemicals equipment
  • D Mechanical matrix effect
  • E Chemical matrix effect
  • F Area of optimum cleaning efficiency

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

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 fullscale equipment
    implement experimental findings in a practical way
