EWS For Petro
OriginOil’s proprietary Electro Water Separation™ (EWS) technology is particularly effective in the treatment of produced and frack flowback water from the oil & gas market.
The EWS process efficiently removes non-soluble organics and inorganics, such as free & dispersed oil and suspended solids, through the two hardware stages of electro-coagulation and electro-flotation.
The result is a high degree of water clarity, to enable better operation of downstream processes.
Together, these stages also accomplish the important third function of electro-oxidation, which is effective in removing bacteria, and certain ions that are capable of being precipitated from solution.
EWS targets the one to twenty-five micron size oil droplets and suspended particles for coagulation and flotation.
Other technologies are less effective at removing these small particles.
How Is EWS Different?
The designs incorporated in EWS technology are unlike other electro-coagulation (EC) systems tried over the years.
Other EC Approaches
Typical EC systems have been stand-alone systems with separate pieces of equipment for gravity separation and disinfection. EWS integrates these functions into one stand-alone piece of equipment with SCADA control over all three technologies.
Earlier EC generations have historically used heavy steel plates as the anode and cathode, with wide separation to prevent scaling and high pressure drop through the cell. The wide separation requires high power to achieve the dosage rates required for coagulation.
Our EC Approach
Instead, the EWS electro-coagulation reactors use an outer tube and an inner rod as the cathode and anode with the water flowing through the annular space.
The resultant annular gap and high mass transfer rate minimizes the power necessary to achieve coagulation dosage rates. The high mass transfer rates also prevents scaling.
As a result of the above designs, the EWS EC reactors require far less power with an estimated Selective Energy Consumption of 0.28kWh per barrel of water.
Less anode consumption is seen, and the anodes are far easier to replace and maintain.
Our Electro-Flotation Approach
EWS electro-flotation technology typically utilizes non-donating anodes and cathodes to generate micro-bubbles over the complete volume of water in the flotation chamber. These microbubbles are small enough to embed or attached themselves to the coalesced oil and suspended solid particles.
The flotation chamber itself is also divided into four flotation or separation chambers each which separates larger percentage of the oil and solids leaving progressively clearer water.
Electro-Oxidation vs. UV
The same bank of EC reactors may also utilize reactors with non-donating anodes that generate oxidizing chlorine compounds that both disinfect bacteria and oxidize precipitable ions and metals.
This technology is known as electro-oxidation, which also occurs in the flotation stage of our donating anode configurations. By comparison, other systems for bacteria disinfection typically rely on UV lights.
Superiority over DAF
Dissolved Air Flotation (DAF) systems have two major disadvantages when compared to EWS.First, they depend on chemical coagulant additions for separation.
Second, they recirculate and expose only about 10% of the water to the gases that float the contaminants to the surface of the water.
EWS for Licensing, OriginClear for Purchase
Equipment suppliers who have technology that would benefit from EWS’s pretreatment technology, and system integrators who want to utilize EWS’s pretreatment technology, can license EWS on a private label basis.
Alternatively, OriginOil offers OriginClear Petro.
This is a complete end to end solution with EWS technology at its core.

Technology Without The Wait
OriginClear Petro is for end-users who want the newest technology, without delay. It is also for distributors, suppliers and integrators who want to sell solutions without waiting for manufacturing.
OriginClear Petro removes up to 99.9% of all free, dispersed and emulsified oil, and 99.5% of suspended solids from oil & gas wastewater, while also removing certain dissolved contaminants that will co-precipitate, and continuously disinfecting bacteria.
Available in capacities of 250, 1000 and 5000 barrels per day and beyond, OriginClear Petro bundles OriginOil’s core
EWS technology with ‘heavies’ removal on the front end, intelligent controls, and a final post-polishing system, all in a single product.
OriginClear Petro is a turnkey single-skid system that includes an intelligent power supply, a self- cleaning filter for heavy solids removal on the front end, electro-oxidation reactors, and a polishing system on the back end.
All systems include a common SCADA control system with touch screen which will allow automatic control of the process as well as remote monitoring and alarms.
In some cases OriginClear completes the job. For instance, to treat wastewater for water flooding, the OriginClear system removes all the oil, suspended solids and bacteria and requires no secondary technology. But additional requirements require more processes.
For example, benzene is typically removed with an activated carbon or black walnut shell filters. Or, inorganic salts that cause hardness or scaling in equipment are typically removed with membrane systems. Other chemicals like boron or radionuclides are removed by ion exchange resins. And salts exist which may require evaporation.
OriginClear Petro’s efficient and effective removal of suspended solids clears the pathway for downstream processes to economically treat water for unlimited beneficial uses downstream.
