Advanced Water Treatment Technology

• ElectroPure uses no added chemicals

• Patent-pending technology

• High volume, scalable treatment with three models ranging in flow from 500 – 1000m3 per day. Multiple systems in parallel achieve any flow rate required.


Applications:

• Frac-flowback water • Produced water • Mining waste water • Industrial waste water • Fixed Plant • Mobile Plant

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


• 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
