1. Innovative Flash Evaporation Technology Thermo Oxidizer

2. 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 Reduction of Waste Water Why?

3. 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 Evaporation of Waste Water

4. Traditional Boling Water Evaporator

5. –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 Thermo Oxidation Flash Evaporation of Waste Water

6. Models for 30, 60 & 150 GPH

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

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

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

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

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

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
