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?



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.

Cruise Ship Sanitation

Electrolyzed Oxidizing Water is an eco-friendly and safe alternative to concentrated toxic chemicals. It can replace nearly every chemical for sanitizing staterooms, galleys, restaurants, common areas, floors, and bathrooms. EWCO Sanitizer has been demonstrated to kill over 99.9% (over 3-log reduction) of the most common microbial pathogens including Norovirus.

Combating Norovirus

Norovirus is a contstant struggle on cruise ships. Currently used chemicals are peroxide-based and are highly corrosive. Overused peroxide-based chemicals have become ineffective as Norovirus develops resistance. In addition, peroxides destroy upholstery which can be expensive to repair. Electrolyzed Oxidizing Water is not corrosive to upholstery nor does it cause discoloration. Recent research as demonstrated that Electrolyzed Oxidizing Water can inactive Norovirus on soft and hard contact surfaces with concentrations as low as 100 ppm when applied directly or by fogging.

Hand Sanitation

Hand sanitation plays an important role in preventing and controlling Norovirus outbreaks. EWCO electrolyzed water is safe and non-irritant to hands and skin and can help with hand sanitation. Electrolyzed Oxidizing Water can be placed in hand sanitation dispensers throughout the ship.


Eliminating Chemicals
Eliminating chemicals on cruise ships saves time, space, and money. Chemicals require purchasing, transporting, storing, and preparation. Storage space is limited on ships. Electrolyzed Oxidizing Water is on-site generated and requires minimal storage space. The only ingredients needed are salt, water, and electricity.

Food Safety

Not only can EWCO electrolyzed water (hypochlorous acid) kill the most common pathogens such as staphylococcus and streptococcus bacteria on contact surfaces, but it is effective against the most common foodborne pathogens such as Salmonella, Listeria, and E. coli. To learn more please visit our research page and search by microbe to find applicable research. Electrolyzed Oxidizing Water has been cleared by the FDA for no-rinse sanitation of meat, poultry, seafood, and produce if generated from EWCO systems. See FCN 1811 on the FDA website. EWCO Sanitizer is 100% safe on food. It does not cause any change in the taste or smell of food nor does it cause discoloration. Also see the letter from USDA Organic. There are no harmful residuals. Using electrolyzed water as a no-rinse sanitizer in preparation kitchens for meat, poultry, seafood, and produce can greatly reduce the incidence of foodborne illness.



Replacing toxic chemicals in the kitchen with electrolyzed water (hypochlorous acid) for sanitizing food contact surfaces will save time and add convenience. Sanitizing food preparation areas involves removing all food from the area prior to sanitation and therefore can only be done during designated hours of the day. During peak hours, when cross-contamination is at the greatest risk, no sanitizing is taking place. EWCO Sanitizer solves this problem. Being safe on food, electrolyzed water (hypochlorous acid) can be used in spray bottles to disinfect food preparation areas, cutting boards, equipment, kitchenware, and tables throughout the day without having remove or cover up food therefore controlling cross-contamination during all hours of the day.

Employee Safety

Preparation of toxic concentrated chemicals can be a safety hazard for employees as they are respiratory and skin irritants. EWCO Cleaner & Sanitizer is 100% safe for employees. It does not require any special handling. It is non-irritant and does not require gloves or masks. It can be applied directly with rags and mops or broadly by fogging and pressure spraying.

Linen Sanitation

EWCO Sanitizer can replace harsh chemicals such as quaternary ammonium (quats) used commonly to sanitize linens. Quats can cause eye irritation and contact dermatitis. For about 5% of people, quats are an extreme sensitizer and can cause a variety of asthma-like symptoms. EWCO Sanitizer is non-irritant and does not cause any respiratory or asthma-like symptoms.

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.
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.

EWCO Water Disinfection

The EWCO 1200 Electrolyzer can disinfect water on-site and on-demand from just salt, water, and electricity.

How much water can it disinfect?

Each system can generate enough free available chlorine in the form of hypochlorous acid to disinfect 200 Liters of water per minute. The systems can be stacked to disinfect any volume of water

How does it work?

The EWCO 1200 Electrolyzer generates a mixed oxidant solution primarily composed of hypochlorous acid (HOCl) but also other powerful oxidants such as ozone and chlorine dioxide. Hypochlorous acid is a powerful oxidant that is stable in solution that can kill microbial pathogens immediately upon contact by damaging cell walls and disrupting internal proteins, lipids, and DNA.

Has it been researched?



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.
EWCO electrolyzers eliminate the need for purchasing, transporting, storing, and preparing of toxic concentrated chemicals and can meet all the water disinfection needs of the ship by on-site generation. Cruise ships can switch to an environmentally friendly technology while saving time, space, and money.

Electrolytically generated hypochlorous acid eliminates common microbial contaminants:

• Adenovirus
• Caliciviruses (including Norovirus)
• Campylobacter jejuni
• Enterovirus (including polioviruses, coxsakieviruses, and echoviruses)
• Escherichia coli (O157)
• Helicobacter pylori
• Hepatitis A
• Legionella pneumophilia
• Mycobacterium avium
• Salmonella enterica
• Shigella sonnei
