ECA is an abbreviation of
electro-chemical activation

ECA is created via a technology which disinfects water simply by running it through an electrochemical cell.

Depending on the applied voltage, resolved substances within the water and the water itself can be oxidized at the positive charged electrode
(so called anode) or reduced at the negative charged electrode (so called cathode) side.

Activation and redox potential

Some of the oxidized substances, mainly hypochlorous acid formed from chloride contained in the water, are in a so-called meta stable state and try to get back to their original form by oxidizing other, for example organic, substances. Thus, the water coming from the anode side has oxidizing and disinfecting properties. This coincides with an increase of the redox potential (ORP) in the water, which can serve as a measuring parameter for the disinfection potential.

In 1972 the World Health Organization (WHO) recognized in its Standards for Drinking Water that, at an ORP level of 650 mV, water is disinfected and viral inactivation is almost instantaneous. Thus we can call electrolyzed water “activated water”, which is able to inactivate germs and viruses.

Basic principles of the
ECA water production

The basic principle behind the electrochemical activation of water is electrolysis. Electrolysis is a process where chemical substances are transformed into oxidized and reduced forms by applying voltage and current. It is mainly performed with aqueous liquids. The principle was discovered by Alessandro Volta in the year 1800.

Where to use the technology

It is a very effective all-round disinfectant liquid that is both inexpensive to produce and can be used in many different applications. It is safe for people to use and at the same time environmentally friendly.
