1 Total Oil Remediation and Recovery (TORR ) ) Remediate Hydrocarbon Contaminated Groundwater No Additional Waste Created M.J. Plebon EARTH (Canada) Corporation

2 Presentation Objectives To explain the basic fundamentals of oil water separation and the issues facing the industry. To explain the functions of RPA and how it works inside the TORR process. To highlight the results of trials performed and remediation cases to date. 2

3 Who is EARTH (Canada)? Environmental Applied Research Technology House 1994 Environmental R&D Company Federally Incorporated Public Company CDNX: Symbol [EAR] 3

4 EARTH s Mission and Focus EARTH specializes in the development and commercialization of environmental cutting-edge remediation solutions to separate and recover oil and other hydrocarbons from water, soil and air. All of EARTH (Canada) s Technologies revolve around its patented Reusable Petroleum Absorbent - RPA. 4

5 Oil / Water Separation Theory

6 Oil / Water Separation Theory Stoke s s Law V r = g d 2 (ρ w - ρ o ) / 18 η Where: V r = rise velocity of oil droplet g d ρ w ρ o η = acceleration due to gravity = oil particle diameter = density of water = density of oil = viscosity of water 6

7 Oil / Water Separation Theory V r = g d 2 (ρ w - ρ o ) / 18 η Droplet size has the largest impact on rise velocity of oil. 7

12 RPA - Reusable Petroleum Absorbent?

13 What is RPA? RPA is an inert oleophillic & hydrophobic thermoset polymeric material backbone. Organic substance produced in granular form. RPA Performance Claim Verified Non-toxic, chemically neutral & environmentally safe. RPA absorbs oil & is reusable 100 times. 13

14 The TORR Process (Total Oil Remediation & Recovery)

15 What is TORR? TORR is the latest development in hydrocarbon separation from water. TORR incorporates RPA into a continuous treatment process. TORR separates hydrocarbons and recovers them for reuse or recycling. Water is treated to well below 5 ppm hydrocarbon concentration (>2 µm) m). 15

16 EARTH (Canada) Corporation Environmental Applied Research Technology House Oily water is sent from holding tank to TORR to be treated. TORR Technology

17 EARTH (Canada) Corporation Environmental Applied Research Technology House Oily water is sent from holding tank to TORR to be treated. The oily water passes through several sections of RPA. Each section is separated by an empty chamber. TORR Technology RPA RPA

18 EARTH (Canada) Corporation Environmental Applied Research Technology House Oily water is sent from holding tank to TORR to be treated. Magnified View Oily Water with fine emulsions R P A TORR Technology RPA absorbs the oil emulsions and continues to absorb oil until it saturates. Once saturated, the RPA releases larger coalesced oil globules. The RPA then continues to absorb additional oil emulsions and the absorption/desorbtion process repeats. R P A RPA

19 EARTH (Canada) Corporation Environmental Applied Research Technology House Oily water is sent from holding tank to TORR to be treated. The coalesced oil globules are then sent to an oil recovery chamber where rapid separation occurs and oil is recovered. Oily Water with fine emulsions R P A R P A Coalesced oil Coalesced oil TORR Technology RPA The coalesced oil globules are collected from the chamber via the collection manifold.

Oily Water with fine emulsions R P A R P A Coalesced oil Coalesced oil TORR Technology RPA The effluent water will have its hydrocarbon content reduced to below 5 ppm for emulsions 2 microns and greater. Treated Water < 5 ppm

21 Benefits of TORR Addresses broad spectrum of emulsion droplet sizes. (>2µm)( No waste is created. Hydrocarbon recovery and recycling. No heat or chemicals needed. Low operating costs. Low maintenance costs. High flow rates. Small footprint. Stand alone or part of a system. 21

22 Fort Smith Groundwater Remediation Project

23 The Challenge Heating oil tank at Aurora College had been leaking since 1972 Groundwater needed treatment before being discharged back to the environment. Transportation and disposal of traditional GAC too costly. Required a technology that would keep overall treatment costs manageable. 23

24 Fort Smith NWT Remediation Project 24

25 Fort Smith NWT Remediation Project 25

26 Results Over 20,000 m 3 treated TPH levels of treated groundwater = non-detectable No disposal of GAC needed. Project completed on time and well within budget. 26
