Breakthrough water cleanup technology.

Electro Water Separation

Winning in the most challenging water environments.

By 2030, water demand will outstrip supply worldwide*. This growing emergency is driving the need for more efficient water reclamation.

But a great deal of water is so loaded with oil products, suspended solids, and dissolved contaminants, that it remains difficult and expensive to fully reclaim it. Often, hazardous chemicals such as chlorine are part of the solution, but create their own special problems.

Electro Water Separation™ (EWS) is a highly scalable, continuous process that uses electricity in small, programmed doses to gather up oils and suspended solids, and through Advanced Oxidation or AOx, to remove fine, micron-sized suspended solids, and dissolved contaminants such as ammonia.

Electro Coagulation (EC): the process begins.

Waste water enters the system through continuous tube-shaped inline reactors. These create extended residence time while keeping the process continuous. In these tubes, metal ions are transferred to trigger particle aggregation. The process can be designed to use degrading anodes, or to operate without any anode degradation whatsoever, as the application requires.

This stage coagulates the suspended solids, oil and grease, and non-soluble organics so they can be removed in the next stage, Electro-Flotation.

The generation of Reactive Oxygen Species (ROS) begins here. ROS are ozone, hydrogen peroxide and hydroxyls. These can degrade virtually any 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 wanting to avoid managing hazardous materials.

Electro-Flotation (EF): separating the suspended solids.

During the Electro-Flotation stage, an array of reactors at the bottom of the flotation tank produces gases electrochemically, resulting in a finely bubbled “cloud”.

This stage separates the suspended coagulated material and completes the process of breaking the oil emulsion. It creates a “mat” of aggregated waste which it pushes to the surface for mechanical removal.

ROS continue to be generated here, preparing for Advanced Oxidation or AOx.

Advanced Oxidation (AOx): disinfection and decontamination.

The EWS:AOx™ research team developed AOx as an evolution of known Advanced Oxidation processes.

The AOX reactor takes water that is largely clear of suspended solids and oils. In the earlier stages, it has begun to acquire disinfecting and decontaminating oxidants: Reactive Oxygen Species or ROS.

In the AOx reactor, reaction with the anode surface inside the reactor causes the on-site generation of a large amount of ROS.

“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 Eckelberry
At this stage, fine, micron-sized suspended solids, and dissolved contaminants, will precipitate and sink to the bottom of the AOx tank for removal.

Depending on the application requirements, AOx can be implemented either in tube-shaped inline Advanced Oxidation Reactors or in an Advanced Oxidation tank, both featuring OriginClear’s patented reactor design.

AOx can also generate other compounds through electro-chemistry, such as chlorine, to address specific contaminants such as ammonia, phosphorus or hydrogen sulfide (H2S).

The complete system, including Advanced Oxidation, is known as EWS:AOx.

Effective in water-intensive industries.

Because of its impressive feature set, EWS:AOx is valuable in water-intensive industries such as oil & gas, agriculture including algae production, and industrial wastewater management.

EWS:AOx is currently deployed in various industry applications ranging from cleaning up produced water or “frack” flowback water in oil and gas well operations, to harvesting algae for beneficial products such as fish feed.

EWS:AOx is entirely developed in-house by OriginClear and is protected by patents, and patents pending, worldwide.

Continuously fast and extremely thorough cleaning.

This multi-stage process is an energy-efficient, continuous system that advanced testing has shown can achieve up to a 99.9% removal of dispersed oil and a 99.5% removal of suspended solids and organics*, as well as specific contaminants such as ammonia, phosphorus and hydrogen sulfide.

EWS:AOx  powers the water cleanup systems that are marketed by OriginClear’s licensing and joint venture partners.

Proprietary electrode arrays.

A specific feature of EWS:AOx is the proprietary design of the electrodes where Electro-Coagulation, Electro-Flotation and Electro-Oxidation work in sequence.

Their design provides the most efficient contact and mixing method for the processed fluids and the reactive species, and their specificity is a combination of anode/cathode shape, size, position, as well as selection of the electrode materials.

Solid-state process control.

The heart of EWS:AOx is a proprietary solid-state process control unit (PCU) that controls the entire process, and customizes the power requirements of each application. We are continuously evolving new features to reduce operator intervention and standardize the operating parameters.

We are also implementing machine links to the cloud for authentication, remote operation, diagnostics, and software updates.

We have designed this control system to maintain maximum operating uptime for all OriginClear systems in the field, working for both end-users and service companies.
