4 ElectroPure (EPT) Technology The Royal Treatment

5 ElectroPure (EPT) Technology

6 Process Overview Oil water separator Electro coagulation Electro catalytic oxidation Electro floatation/clarification Filtration

7 EPT - Trailer

8 Oil / Water Separation Oil removal capacity of less than 5ppm using diffused air floatation and coalescing media

9 2 Stage Electrolytic Reactor Electrolytic cells are the heart of the ElectoPure system.

10 Electrocoagulation EC destabilizes these charges allowing for coagulation to occur Seeding Emulsion Breaking Oxidation Reduction reactions

12 Electro catalytic Oxidation Electrocatalyst (MMO)Mixed Metal Oxide electrodes. Iridium coated Titanium The electrolytic process hydroxyl free radicals, sodium hypochlorite, ozone and other halogens creating oxidationreduction reactions within the liquid.

13 Electro-Flotation/ Clarification Electro-flotation - electric charge passing between the reactor plates, generates an enormous volume of extremely fine gas bubbles with a bubble size in the range 25um 30um. The volume of gas bubbles is understood to be in the millions per liter of liquid. Clarification- Gravity separation of heavy solids is achieved via a slant plate clarification system

19 Particle Plugging Theory Hexagonal Packing of Frac Sand Grains D D = diameter of frac sand d = diameter of pore throat d d = (0.1547)D

20 Particle Plugging Theory Rule of Thumb: Particles with diameters of 1/3 rd to 1/7 th of the pore throat diameters will bridge and plug the pores

23 Case Study 1 Slick Frac Flowback Water Reuse for Foam Frac in the Montney, NW Alberta An oil and gas producer wants to reuse its slick frac flowback water in subsequent fracs. The goal of using ElectroPure was to treat to criteria for reuse in the next frac, which is a foam frac, typically requiring high quality water.

25 Influen Results t Case Study Slick Frac Flowback Water Reuse for Foam Frac in the Montney, NW Alberta EC Ozone Separation /Clarificati on 5 micron filtration Multi Media filtration

26 Case Study 1 Particle Influent Effluent Size (micron) TSS (mg/l) TSS (mg/l) < TOTAL TOTAL < (97.5%) x 14,000,000 litres treated = 14,428 kg of solids removed that will attribute to plug flow *40/70 frac sand used Critical plugging range 5 22 micron

27 Case Study 1 Conclusion ElectroPure technology was successful in treating the slick frac flowback water to well below criteria for all required parameters for reuse in the subsequent foam frac. These included TSS, metals and hydrocarbons. The ElectroPure system treated 14,000,000 litres of water on this project and removed a total of 14,400 kg of sludge.

28 Case Study 2 Gel Frac Flowback Water Reuse Near Edson, Alberta The goal of using ElectroPure was to treat to criteria for reuse in the next frac, which is a gel frac, typically requiring fresh water.

30 Case Study 2 Conclusion ElectroPure technology was successful in treating the Gel frac flowback water to reuse standards at 0% dilution. The Frac company was able to regel.

31 Case Study 3 Produced Water with H2S Near Grand Prairie, Alberta The goal of using ElectroPure was to treat to Produced Water with H2S to use for fraccing, which is a gel frac, typically requiring fresh water. 80,000 ppm H2S produced water

32 H 2 S

33 Case Study 3 Conclusion ElectroPure technology was successful in treating the Produced water to reuse standards from 80,000 ppm H2S to 0 ppm.
