ECA Technology
Electro-chemical activation (ECA) technology is a process that involves the electrolysis of a solution containing water and a small amount of salt, resulting in the generation of two key components: an alkaline solution (catholyte) and an acidic solution (anolyte). These solutions can be used for various applications such as disinfection, cleaning, and water treatment.
Here's a breakdown of how ECA technology works:
-
Electrolysis Cell: The ECA process starts with an electrolysis cell, which consists of two electrodes—an anode and a cathode—immersed in the electrolyte solution. The electrodes are typically made of a stable material like titanium or platinum.
-
Salt Solution: A small amount of salt, usually sodium chloride (NaCl), is added to the water to increase its conductivity. The salt dissociates into positive ions (sodium, Na+) and negative ions (chloride, Cl-) in the solution.
-
Electrolysis Process: When an electric current is applied to the electrolysis cell, several reactions occur at the electrodes:
a. At the anode: The chloride ions (Cl-) lose electrons and get oxidized, forming chlorine gas (Cl2) or hypochlorous acid (HOCl) depending on the specific conditions. These compounds are responsible for the antimicrobial properties of the resulting acidic anolyte.
b. At the cathode: The water molecules (H2O) near the cathode gain electrons and undergo reduction, forming hydroxide ions (OH-) and hydrogen gas (H2). The hydroxide ions contribute to the alkalinity of the resulting catholyte.
-
Separation: The generated anolyte and catholyte are separated and collected for their respective applications. The anolyte, with its acidic properties and antimicrobial agents, can be used as a disinfectant or sanitizer. The catholyte, with its alkaline properties, can be used for cleaning or as an environmentally friendly alternative to traditional cleaning agents.
It's important to note that the composition and properties of the resulting solutions can vary depending on factors such as the type and concentration of salt used, the pH of the solution, and the applied electrical current. Different ECA systems may have variations in their setup, but the basic principle of electrolysis and the generation of anolyte and catholyte remain the same.
ECA technology offers several advantages, including the production of environmentally friendly and non-toxic solutions on-site, reduced reliance on chemical additives, and potential cost savings in various industries where these solutions are used.
