EWCO Water Treatment

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. Water Disinfection
Commercial Water Purification

Whether it be for a small business or restaurant or for a large business, commercial building, or hotel, EWCO can design a custom-built CDI system to purify the drinking water. EWCO can design custom-built CDI systems which remove contaminants at the point of entry from the city water supply. By running public water through an EWCO CDI before it comes out of the tap, you can help ensure that your water is clean and safe from inorganic contaminants.

Water Disinfection

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
EWCO Electrolyzers can disinfect potable drinking without using toxic concentrated chemicals.

Disinfecting Drinking Water

Electrolytically generated hypochlorous acid is 100 times more effective as a potable drinking water disinfectant than chlorine bleach.

EWCO electrolyzers can disinfect all the potable drinking water for a small or large business.

Killing Microbial Pathogens
EWCO electrolyzers generate a powerful mixed oxidant solution that inactivate microbial pathogens by damaging their cell walls and disrupting their internal proteins, lipids, and DNA.

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?

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.

Commercial Water Disinfection

EWCO Electrolyzers can be installed to disinfect well water or public drinking water. Much of our drinking water infrastructure is nearing the end of its useful life. There are an estimated 240,000 water main breaks per year in the United States. In some areas the pipes are more than 100 years old and in need of replacement. Because of poor infrastructure, many restaurants, residential buildings, office buildings, and hospitals are at risk of outbreaks of disease attributable to drinking water. EWCO Electrolyzers can help ensure water disinfection by electrolyzing the water as it comes into the building.

Water Disinfection 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
