  1. Introduction toEnviroTech Electrocoagulation

  2. Electro-what?!?

  3. Environmental Protection Agency (EPA) Environmental Technology Verification Program (ETV) • Research on ETIG (through KASELCO partner) Electro-coagulation technology is peer reviewed by ETV • Here are research papers from ETV http://www.epa.gov/etv/pdfs/vrvs/06_vr_kaselco_vs.pdfhttp://www.epa.gov/etvprgrm/pdfs/testplan/06_tp_kaselco.pdf

  4. Introduction toEnviroTech InternationalELECTROCOAGULATION

  5. Electrocoagulation History • 1906 - Dieterich Patent • Bilge Water Treatment • 1980’s - Revival • 1988 - Article in Products Finishing Magazine • 1999 - First Kaselco Patent • 2001 - Second Kaselco Patent • 2003 - Third Kaselco Patent

  6. First Prototype Cell Early prototype configuration

  7. Interior Reactor Design

  8. Present Applications • Metal Finishing - Plating • Remediation • Tannery (South Africa) • Emulsified Oils • Bilge Water • Die Casting • Truck Wash

  9. EnviroTech Plating Application Rectifiers and Controllers for Electrocoagulation Reactors at EnviroTech Electroplating

  10. EnviroTech Electroplating Application

  11. EnviroTech 2.27 tons/hour System

  12. EnviroTech Plating Laboratory

  13. EnviroTech Plating Laboratory • Spectroscope • Distiller • Digester • AA (not shown)

  14. EnviroTech LAB Atomic Absorption Spectrophotometer

  15. Electrocoagulation Concepts

  16. Chemical Reactions • Metals + Oxygen + Iron • Hexavalent Chromium + Hydrogen Ion • pH • Oils + Oxygen • Bacteria + Oxygen or Hydroxyl Ion • Dyes + Hydrogen or Oxygen

  17. Operating Costs – 12.5 tons/hour Unit • Bilge Water with Refinery Water Costs Reduced 50% Productivity Doubled Added 13 Ships Eliminated One Shift

  18. Operating Costs - Plumbing Plater • Decorative Nickel/Chromium Process Reduced sodium metabisulfite 90% Eliminated Plant Odor Eliminated Health Hazard Reduced Sludge 40% Reduced Treatment Cost 70% Met Discharge Standards

  19. EnviroTech Installation • Nickel, Chromium, Zinc, others Reduced Sludge 40% Reduced Chemicals >90% Eliminated 15,000 Kg Salts in River Assured Compliance with Standards

  20. EnviroTech Electroplating Application

  21. General Benefits • Reduced Treatment Cost • Reduced Chemical Usage • Reduced Sludge Generation • Simple Operation • Broad Spectrum of Treatment • Cleaner Effluent • Less Salt in Discharge • Lower Concentration of Contaminants

  22. Typical Results • CONTAMINANT INFLUENT mg/l EFFLUENT mg/l • Oil Pipeline: • TPH 2,900 31.7 • Oil and Grease 2,180 <5.0 • Bilge Water: • Turbidity (FAU) 455 12 • Steel Coating: • Chromium 36.63 <0.005 • Cooling Tower: • Copper 1.96 <0.005 • Zinc 6.921 <0.005

  23. Typical Results • CONTAMINANT INFLUENT mg/l EFFLUENT mg/l • Die Caster: • Iron 1,520 1.5 • Nickel >25 0.12 • Zinc 12 <LDL • Manganese 200 <LDL • Plater: • Phosphate 135 25 • Copper 14.1 0.2 • Lead 377.6 0.8 • Clarity (FAU) 2,737 57
