What is Electrolyzed Oxidizing Water?

Electrolyzed Oxidizing Water is electrolytically generated hypochlorous acid (HOCl), a neutral-to-acidic electrolyzed water. HOCl has been studied for over 100 years and it is an undeniable fact that it is a more powerful oxidant than chlorine bleach. Only within the last 30 years have we been able to generate solutions of near 100% HOCl in such a stable form. HOCl kills bacteria, bacterial spores, and viruses 100 times more effectively than chlorine bleach.

How does it work?

Electrolyzed Oxidizing Water is a powerful oxidant (800 to 1000 mV) that can kill microbial pathogens immediately upon contact by damaging cell walls or inactivate the pathogen by entering and disrupting proteins, lipids, and DNA.

What about regulation from FDA, USDA, and EPA?

We have pages dedicated to the regulation of electrolyzed water as it pertains to the FDA, USDA, and EPA. Please visit our pages for more information. In regards to healthcare sanitation, see our page for the CDC.

School Sanitation

Electrolyzed Oxidizing Water (EOW) is an eco-friendly sanitizer that is 100% safe and non-toxic. It can be used to replace all the chemicals used in schools for cleaning and sanitation. Schools have many shared contact surfaces that can be contaminated with bacteria and viruses spread by skin flora and respiratory droplets. Common bacteria that contaminate contact surfaces include bacteria such as staphylococcus and streptococcus and viruses such as Adenovirus, Influenza, and Norovirus.

Sanitizing Classrooms

Food Safety

Not only can EOW kill the most common microbial pathogens spread from skin flora and respiratory droplets, but it is effective against the most common foodborne pathogens as well. EOW can inactivate foodborne pathogens such as Salmonella, Listeria, and E. coli. EOW is 100% safe on food and can be used for routine sanitation of school kitchens, preparation areas, food serving areas, and eating areas.

Sanitizing School Cafeterias

Employee Safety

EOW is generated on-site and on-demand. The only ingredients needed are salt, water, and electricity. Concentrated chemicals require purchasing, transporting, storing, and preparation. Preparation of toxic concentrated chemicals can be a safety hazard for employees as they are respiratory and skin irritants. EOW is 100% safe for employees. It does not require any special handling. It is non-irritant and does not require gloves or masks.

Application by Direct Application, Spraying, and Fogging

EOW can be applied using many different methods. Not only can it be applied directly with rags and mops, but it can also be applied broadly using pressure sprayers and foggers. Pressure sprayers can be used to sanitize floors and hard surfaces. Classrooms, gyms, and other large common areas can be sanitized and deodorized using fogging.

EWCO Water Purification

Capacitive Deionization (CDI) has over a 95% water recovery rate, does not require water softening, is low maintenance, and purifies at a fraction of the cost of reverse osmosis.

Removing Inorganic Contaminants

CDI effectively removes most inorganic contaminants that are charged species such as nitrates, ammonia, arsenic, lead, flouride, magnesium, calcium, and total dissolved solids (TDS) or salinity.

Removing Organic Contaminants

CDI can also remove organic contaminants if they have a charge. However, most organic contaminants can be removed by activated carbon filters prior to running through the CDI.

Removing Radionuclides

CDI can remove radionuclide contaminants such as alpha particles, beta particles, Radium, and Uranium.
EWCO Water Purification

EWCO builds water purification systems using membrane capacitive deionization (CDI) technology.

How much water can it purify?

EWCO CDI systems can be stacked with any number of CDI cells to meet the need of any project small or large. Whether it be for a home, business, manufacturing plant, or municipality, EWCO can custom build a CDI system specific to any application.

How does it work?

CDI is a technology to purify water by applying an electrical potential difference over two porous carbon electrodes. Anions (negative charge) are removed from the water and are stored in the positively polarized electrode. Likewise, cations (positive charge) are stored in the cathode, which is the negatively polarized electrode. Membrane Capacitive Deionization
Removing Contaminants

CDI is able to effectively remove the following water contaminants:

  • Temporary Hardness: Ca , Mg
  • Total Hardness: CaCl2 , MgCl2 , CaSo4 , MgSO4
  • Total Dissolved Solids (TDS)
  • Chlorides and Sulphates
  • Sodium chloride: NaCl
  • Sodium Sulphate: Na2SO4
  • Nitrate Anion NO3
  • Nitrite Anion NO2
  • Ammonia NH4+
  • Iron (Fe) (when present in ionic form)
  • Magnesium (Mm) (when present in ionic form)
  • High level of oxidizers (when connected with humic acid)
  • Organic Micro pollutant (when present in dissociated form)
  • Hexavalent chrome
  • Arsenic
  • Fluorides
  • Heavy Metals

EWCO CDI systems can be designed, engineered, and custom built to meet the needs of almost any application. The percentage of demineralization can be varied based on the specific water needs. This can be done by varying the potential difference across the electrodes from 1 to 1.6V. This characteristic, unique in respect to all other water purification technologies in the industry, allows for the alteration of the water's taste.

CDI Advantages

EWCO CDI has many advantages over Reverse Osmosis (RO):

  • Minimal Water Wasted - Compared to conventional RO systems that waste more than 30% of the water, the maximum water wasted in EWCO CDI systems is less than 10%. This results in long-term conservation of ground water.

  • Lower Operating Cost - EWCO CDI systems use no chemicals and have lower consumable requirements for operation. The systems consume less power and the total cost of producing treated water is in the range of 1 cent per 10 liters

  • Simplistic Operation - EWCO CDI systems have a built in controller that automates the working of the system in local conditions and the entire system can be managed with little or no training.

  • Small Footprint - A typical EWCO CDI system requires very little space to operate. EWCO can build systems for homes that are small enough for a countertop or systems large enought to meet the needs of municipalities.

  • Environmentally Friendly - Since EWCO CDI systems do not use any chemicals for treatment, the water drained from the system does not contain any chemicals that are hazardous to the environment. This ensures the safe release of water back to the environment.

  • Retention of Beneficial Minerals - Unlike water treatment in a typical Reverse Osmosis system, where most of the minerals are removed from the incoming water, EWCO CDI systems can be set to retain desired levels of minerals that are beneficial to the human body.

Has it been researched?

Research Publications

In the last 30 years we have collected over 300 published research articles supporting the use of Electrolyzed Oxidizing Water for disinfection. Nearly every common bacteria has been studied as well as viruses and fungi. To learn more please visit our research page and search by microbe to find applicable research.

What about EPA regulation?

Because electrolytically generated hypochlorous acid is a free chlorine molecule, it falls under the Safe Water Drinking Act (42 U.S.C. 300f et seq. 1974) which allows for a free chlorine concentration of up to 4 ppm.

Inactivating Microbial Contaminants

Water disinfection by electrochemical activation is not only more effective than conventional methods of water disinfection, but it is less expensive and environmentally friendly.

The conventional methods, which have seen extensive use over the last 100 years, include chlorine gas and chlorine solutions of sodium hypochlorite (bleach). Despite the vast amount of experience gained over the years, these methods have disadvantages, including the cost of the chemicals and the large investment required for protection and safety equipment.

Electrolytically generated hypochlorous acid is 100 times more effective than sodium hypochlorite yet requires no protective gear or safety equipment and is non-toxic, non-irritant, and eco-friendly. Water Disinfection

Electrically generated hypochlorous acid eliminates common microbial contaminants:

  • Adenovirus
  • Caliciviruses (including Norovirus)
  • Campylobacter jejuni
  • Enterovirus (including polioviruses, coxsakieviruses, and echoviruses)
  • Escherichia coli (O157)
