On-Site Generated Electrolyzed Water


Electrolyzed Oxidizing Water


Sanitizing Fish and Seafood

Electrolyzed Oxidizing Water has been cleared by the FDA for no-rinse sanitation of fish and seafood if generated from EWCO systems. See FCN 1811 on the FDA website. Also see the letter from USDA Organic.

Process Water for Fish & Seafood

Electrolyzed Oxidizing Water is FDA cleared for use in process water for fish and seafood if generated from EWCO systems. See FCN 1811 on the FDA website. Also see the letter from USDA Organic.

Sanitized Ice for Fish & Seafood
Electrolyzed Oxidizing Water is all natural and safe. It can be used to generate sanitized ice for storing fish and seafood.
Seafood Processing Equipment Sanitation
Electrolyzed Oxidizing Water is a safe and effective antimicrobial for food contact surfaces and equipment. No post-rinse with potable water is required.

Hand and Feet Sanitation
Electrolyzed Oxidizing Water is safe and non-irritant and can be used to help sanitize hands and feet prior to entering a facility.
Floors and Bathrooms Sanitation
Electrolyzed Oxidizing Water can be used to sanitize contact surfaces, floors, and bathrooms. It can replace chemical sanitizers such as quats, peroxide, and bleach. It does not cause discoloration as seen with chlorine bleach.

On-Site and On-Demand

EWCO systems are compact and easy to install. Systems are designed to generate Electrolyzed Oxidizing Water on-site and on-demand from an additive made yourself with just table salt and water.

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.

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. Nearly every common bacterial pathogen has been studied such as E. coli, Salmonella, Listeria, Vibrio, Staphylococcus, MRSA, spore forming bacteria, and many common viruses (including Norovirus) and fungi. To learn more please visit our research page and search by microbe or industry to find applicable research.

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.


Fish & Seafood Plant Sanitation

Electrolyzed Oxidizing Water (EOW) is an ideal antimicrobial for fish and seafood processors. Proper sanitation of the food processing environment is paramount to keeping the initial microbial load to a minimum. EOW can control microbial load and has the added benefits of being non-toxic, non-hazardous, and non-irritant. As an antimicrobial, it can replace nearly all chemical sanitizers. EOW is highly biocidal yet leaves no chemical residues or chemical odors. No potable water post-rinse is required. EOW satisfies the demand for implementing safer and more natural food products.

EOW has many applications in fish and seafood processing:

  • Storing and sanitation of fish and seafood at harvest
  • Dosing into the process water
  • Generating sanitized ice for storing and transporting
  • Employee hand and feet sanitation entering the facilities
  • Sanitation of processing tools and equipment
  • Sanitation of floors and food contact surfaces
  • Dislodging bioflim and sanitizing pipes and closed systems

Fish & Seafood Harvest

Seafood contamination occurs naturally from the environment where fish are harvested. Microbial pathogens and spoilage organisms can expediate the decomposition of fish. By placing fresh catches into electrolyzed sanitation water, microbial organisms can be kept at low levels, keeping the catch fresh and prolonging the shelf-life.

Direct Sanitation of Fish & Seafood

When fish are filleted, deboned, packaged and frozen, before distribution, exposure of the fish to water constitutes one of the critical steps that must be optimally controlled in order to prevent the introduction of pathogens. The water used in the processing of fish needs to be clean with minimal levels of spoilage organisms and free of pathogens. Cross contamination may occur during food processing where bacteria are transferred from raw fish and/or contaminated surfaces to hygienically safe fish and seafood. Sanitizing seafood with EOW helps prevent cross contamination and satisfies the demand for implementing safer and more natural food sanitation without adversely affecting food quality. There are no chemical residues, no odors, and no changes in taste or color. No post-rinse is required.

Sanitized Ice for Transport and Storage

Sanitized ice can be generated with EOW. Sanitized ice can be used in the transport and storage of seafood to maintain freshness. Sanitize ice made with electrolyzed water (hypochlorous acid) halts the growth of microbial organisms.

Pressure Spraying and Fogging

When cleaning and sanitizing contact surfaces, tools, equipment or large open areas, EOW can be appied via pressure sprayers or foggers. The active molecule in EOW is hypochlorous acid, a powerful oxidant that is stable in solution. Hypochlorous acid is approved by the EPA for use on food contact surfaces at concentrations as high as 200 ppm. EOW is highly effective at inactivating microbial pathogens when making contact in liquid form.

Eliminating Chemicals and Employee Safety

EWCO electrolyzers eliminate the need for purchasing, transporting, storing, and preparing of toxic concentrated chemicals. Processing plants can switch to an environmentally friendly technology while saving time, space, and money. Electrolyzed water composed of 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.
