Innovative Flash Evaporation Technology

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
