ElectroPure Flowchart
• Oil removal capacity of less than 5ppm using diffused air floatation and coalescing media
• Removal of hydrocarbons allows for more effective and efficient treatment of waste water
Oil/Water Separation
Oil/Water Separation
Electrocatalytic Oxidation
• Electrolytic cells are the heart of the ElectoPure system
• The electrolytic cells create a reactive and excited state causing
contaminants to be released from the water and able to be removed
• Released ions neutralize the charges of the particles, thereby
initiating coagulation • Released ions remove undesirable contaminants by chemical
reactions that promote precipitation and/or flotation • Ionization, electrolysis, hydrolysis and other free radical
formation can also occur
Electrocatalytic Oxidation
• Coagulation is the most important physio-chemical reactions occurring
• Ions and colloids are held in solution by electrical charges
• EC destabilizes these charges allowing for coagulation to
occur • Coagulation occurs by reducing the net surface charge to
a point where the colloidal particles can overcome electrostatic repulsion and allow aggregation to occur

Hydroxyl Oxidation Reactor
• Ozone is highly unstable gas that readily donates its extra oxygen molecule to free radical species
• Very destructive to organic materials, including
microorganisms
• No residual in treated water • Reduces surface tension of water creating “slick
water” thereby reducing need for friction reducers.
Hydroxyl Oxidation Reactor
Micro Sand Filtration
• 0.4 micron filtration • No consumables • Auto backwash
Micro Sand Filtration
Optional Filtration
• Nanofiltration • GAC • Ultrafiltration
ElectroPure Control System
• Intelligent integrated touch screen control panel lets you control the entire system
• Satellite telemetry system (STS) is a web server
technology that allows you to monitor, optimize and operate the ElectroPure system from anywhere in the world, anytime and in real time
• GEE STS gives you trend analysis data when you
want it
