Breakthrough water cleanup technology.

Advanced Oxidation (AOx)

In 2016, OriginClear announced that it successfully developed and proved its proprietary Advanced Oxidation process, AOx, to complement its breakthrough water cleanup system, Electro Water Separation™, or EWS. University laboratory tests have shown that EWS with Advanced Oxidation (EWS:AOx™) can now abate dissolved contaminants, which are otherwise difficult to remove without chemicals such as chlorine.

Advanced Oxidation (AOx): disinfection and decontamination.

“EWS already generates 370mg per second of gas, which is more than twice the amount needed for the removal by electro-flotation of a 2000 mg/l solids contents wastewater. Now, we have confirmed that EWS with Advanced Oxidation also produced more than 330 g/m3 of mixed ROS species, such as hydrogen peroxide, for a similar average energy consumption of 1 kWh per m3 of treated water.”
Dr. Luis Edgar Cabrales Arriaga, assistant professor at the Department of Physics and Engineering at CSU Bakersfield.
The EWS:AOx™ research team developed the AOx module as an evolution of known Advanced Oxidation processes.

The AOx reactor module is specifically designed to focus on the generation of Reactive Oxygen Species (ROS) such as ozone, hydrogen peroxide and hydroxyls.

Recent laboratory studies carried out by the Company in partnership with California State University at Bakersfield (CSU Bakersfield) have indicated the effectiveness of EWS:AOx, as measured by Reactive Oxygen Species (ROS) generation.

ROS are the strongest oxidants that can be used in water and can degrade virtually any contaminant. Their confirmed presence indicates the degree to which the system is able to remove organics from water without chlorine-generated Disinfection By-Products (DPB), which are considered harmful in a waste water treatment system.

The AOx reactor takes water that is largely clear of suspended solids and oils. In the earlier stages, this water 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 on-site generation of an additional large amount of ROS. Targeted cathode material selection triggers other complementary reactions occurring at the cathode surface, addressing contaminants that cannot be oxidized.

“For example, in China, we have been asked to clean up the ‘black water’ contaminants coming out of landfills, which can be so thick that they can clog up any filter. We have shown that EWS:AOx can do the job, and I’m happy to report that we are now in the commercial negotiation phase after a successful demonstration.”

At this stage, the few remaining fine micron-sized suspended solids as well as the dissolved or miscible contaminants will be oxidized or reduced. The resulting elements after these chemical reactions will either precipitate and sink to the bottom of the AOx tank for removal, or dissipate as offgas that can be scrubbed and treated if needed.

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 indirect electro-chemistry reactions, such as chlorine, to address specific contaminants like ammonia.

Being solely composed of oxygen and hydrogen, in-situ generated ROS introduce no additional hazardous element in the water. It is a major benefit for operators wanting to avoid HAZMAT logistics issues, not only when having to treat the concentrated waste, but also as there is no need to bring in and inject oxidants such as Hydrogen Peroxide as it is required in conventional Advanced Oxidation processes.

Dramatic reduction in total organic compounds.

Overall, the system has shown a dramatic reduction in Total Organic Compounds which includes all forms of organic contamination, solids, miscible or dissolved, to meet new stringent global discharge requirements.

Even prior to this innovation, EWS, combined with an iSep ultrafiltration membrane, demonstrated up to a 99.9% removal of dispersed oil, 99.5% removal of suspended solids as well as successful treatment of chemical oxygen demand (COD), including specific contaminants such as ammonia, phosphorus and hydrogen sulfide. These results were presented at the International Water Conference in 2015.

In 2016, OriginClear filed for a patent to protect the new AOx process and system configuration.
