Electrolysed water

Electrolyzed water (also known as electrolyzed oxidizing water, EO water, electro-activated water, or electro-chemically activated water solution) is produced by the electrolysis of ordinary tap water containing dissolved sodium chloride. The electrolysis process separates the water into its two main components: acidic and alkaline water. The acidic water provides sanitizing properties by producing hypochlorous acid (HOCl), a powerful disinfectant, while the alkaline water has surface-cleaning properties. This technology has found applications in a variety of fields including medical sterilization, food safety, and agriculture.

Production

Electrolyzed water is generated by passing a solution of sodium chloride (table salt) and water through an electrolyzer. This device has two electrodes (an anode and a cathode) that are separated by a membrane. When electricity is applied, sodium chloride is converted into chlorine gas at the anode and sodium hydroxide is formed at the cathode. These two substances react in water to form hypochlorous acid, a potent disinfectant, and sodium hydroxide, a cleaning agent.

Properties

The effectiveness of electrolyzed water as a disinfectant is primarily due to the presence of hypochlorous acid, which is known for its rapid antimicrobial activities. It is effective against a wide range of microorganisms including bacteria, viruses, and fungi. The alkaline water produced alongside has a high pH and is used for cleaning purposes, helping to remove dirt and oils.

Applications

Medical Sterilization

In the medical field, electrolyzed water is used for sterilizing medical equipment and surfaces. Its effectiveness against a wide range of pathogens makes it a suitable alternative to traditional chemical disinfectants.

Food Safety

The food industry utilizes electrolyzed water to sanitize food products, equipment, and surfaces, thereby reducing the risk of foodborne illnesses. It is particularly effective in killing bacteria on fruits, vegetables, and meat without leaving harmful residues.

Agriculture

In agriculture, electrolyzed water is used to treat plants and soil, controlling the spread of diseases and pests. It is also used for sanitizing animal enclosures, ensuring a healthier environment for livestock.

Advantages

The primary advantage of electrolyzed water is its non-toxic nature, making it safe for humans and the environment. It does not produce harmful residues or by-products. Additionally, it is cost-effective, as it can be produced on-site using only water and table salt.

Limitations

Despite its benefits, the use of electrolyzed water has limitations. Its effectiveness can be influenced by factors such as water hardness and the presence of organic matter. Moreover, the stability of the produced solution can be a concern, as it tends to lose its potency over time.

Conclusion

Electrolyzed water represents a promising technology in the fields of disinfection and cleaning. Its environmental safety, combined with its effectiveness against a wide range of pathogens, makes it a valuable tool in promoting public health and safety.
