EWS Water Treatment Technology
Electro Water Separation (EWS)
Electro Water Separation™ (EWS) is a highly scalable, continuous breakthrough water cleanup technology that uses electricity in small, programmed doses to gather up oils and suspended solids. The removal of these suspended solids allows for easy mechanical raking off the surface of the water. This ultimately results in the recovery of large qualities of water that can then be reused.
Electro Coagulation (EC): the process begins.
Waste water enters the system through continuous tube-shaped inline Electro Catalytic Reactors. These reactors optimize contact between their active components and the water flux. The process is an energy efficient continuous system.
“Our technology can also treat dissolved organics, such as ammonia, phosphorus and hydrogen sulfide, which are difficult to remove. We’ve found that EWS:AOx delivers twice the functions in one system, for equivalent energy inputs.”
OriginClear’s Chief Inventor, Nicholas EckelberryThis part of the process can be designed to use donating anodes that directly release these ions in the water/contaminants matrix, or to operate using non-degrading Dynamically Stable Anodes, where previously injected ions are thoroughly mixed, as the application requires.
This stage coagulates the suspended solids, oil, grease and non-soluble organics and breaks the oil emulsion, so that all of these can be removed in the next stage, Electro-Flotation.
The generation of Reactive Oxygen Species (ROS) begins here. ROS are highly oxidant molecules such ozone, hydrogen peroxide and hydroxyls. Advanced testing has shown that these can degrade virtually any organic contaminant found in water. Being solely composed of oxygen and hydrogen, they also introduce no additional hazardous element in the water, a major benefit for operators.
Electro-Flotation: separating the suspended matter.
During the Electro-Flotation stage, an array of reactors at the bottom of the flotation tank produces gases electrochemically, in a controlled manner, resulting in a finely bubbled “cloud”.
This stage separates the suspended coagulated material and completes the process of breaking the oil emulsion initiated in the previous stage. It creates a “mat” of aggregated waste which it pushes to the surface for mechanical removal. In the case of algae harvesting, this aggregated waste can be a useful resource.
ROS continue to be generated here, preparing for Advanced Oxidation or AOx.
