  1. Innovative Flash Evaporation Technology Thermo Oxidizer

  2. Reduction of Waste Water Why? • Reduce the amount hauled from facility • Remove the water content from the waste water • Reduce disposal costs • Municipalities will not accept industrial waste water • Reduce or remove the liability • Cradle to grave • Clean up costs

  3. Evaporation of Waste Water • Conventional Technology • Standard evaporators boil waste water at 212 degrees F • Concentration of contaminants increase emissions • Reduced efficiency from insulating heat transfer medium • Mechanical failures from level switches, solenoids, metal fatigue

  4. Traditional Boling Water Evaporator

  5. Thermo Oxidation Flash Evaporation of Waste Water • RGF has applied New,Innovative Technology to evaporate waste water more effectively and more efficiently • Fuel Sources: • Natural Gas • LP Gas • Diesel Fuel • Waste Oil

  6. Models for 30, 60 & 150 GPH

  7. Atomization of Waste Stream provides Flash Evaporation • Dry ash residue • No concentrated slurry • VOC Destruction • No concentration of volatiles • Continuous efficiency • One pass evaporation

  8. Spray Nozzles Injection Port Auto Cleanout Air Atomization 20 Micron Droplets

  9. Modulated Temperature Control • Only use the heat necessary to evaporate • Increase or decrease temperature based on solids loading and/or BTU content • No maintaining heat in a large volume of water • Will control temperature + / - 2 degrees F of selected temperature

  10. Thermal Destruction • Auto ignite temperatures of waste stream components • Example: Propylene Glycol (de-icing fluid) auto ignite temperature is 780º F. The Thermo Oxidizer will be programmed to operate at greater than 780º F to ensure destruction to carbon dioxide

  11. Modulation System Controller Thermocouples

  12. Ceramic Refractory Liner • 3000 degree F capable, fiber reinforced, dense refractory • Up to 5 inches thick

  13. Advantages of Refractory Maintain heat for improved efficiency Secondary evaporation surface Corrosion resistance Cooler exterior

  14. Combustion Air Pre-Heat • Utilize heat loss • Increased efficiency Feed to Burners Blower Suction Air Inlet

  15. PLC Controlled Operation

  16. Safety • Gas Train Meets NFPA 86 Requirements • All functions are monitored • Redundant safety controls • Any control error will disable system.

  17. Optional Waste Oil Burner • Use waste oil to heat unit up to 500,000 BTU/HR @ 3 GPH • Add cost to haul waste oil back into cost to evaporate wastewater

  21. Cost Analysis - ROI

  22. Customer Profile • Denver International Airport • Ramp run off & Fuel Farm waste water • Costs to haul @ 22 cents per gallon • Rain water laden with: • Jet fuel • Hydraulic Fluids • Propylene glycol • Hydrocarbons • Solids

  23. Costs Per Year

  24. Emissions Analysis

  25. Numerous Applications • Die Cast and Metal Working • Cabinet washers • Floor Scrubber wash • Ink and Dye • Vehicle / Aircraft Wash Water • Re-Manufacturing Facilities • Pressure Washer Operations • Plating Operations • Waste Oil Removal

  26. Summary • Liabilities involved with hauling waste water. “Cradle to Grave” • Current treatment technologies- • Membranes- Costly replacement , reject to dispose of and susceptible to variable waste streams • Chemical Precipitation- Labor intensive, large footprint • Encapsulation- Effective treatment but with more maintenance • Evaporation-Best reduction capabilities • Standard technology “Grand Fathered” with respect to evaporation • The Thermo Oxidizer technology • Dry Ash, Consistent efficiency, Flash Evaporation, Thermal Destruction

  27. Case studies

  28. ALTEC • Phosphatizing wash water • 2000 to 3000 gallons per week • less than 200 pounds ash generated after first 8 months of operation

  29. Bosch • Floor scrubber water • Parts rinse water • Solids / emulsified oils • Waste oil burner option • Three system installed

  30. Marine Exhaust • Light Electro polishing • Parts rinse water • Solids / metals • Auto pH control

  31. CTI • Vibratory wash waters • 600gpd • Approved by State of MA • 300,000 gallons evaporated • Less than 250# of ash generated

  32. Schlumberger Well Services • Oil Field Equipment Wash • Removed recycle system • Retained OWS • Evaporates for eight hrs/day • Cleaned once annually • Minimal ash deposits

  33. Eaton • Plating Waste • 10,000 GPD • Eductor System

  34. Parker Hannifin • Multiple waste streams • Parts rinse water • Solids / Trace metals • Replaced R/O System • Save $$$ on discharge to POTW
