The EST series electrolytic water processor is designed specifically for cooling towers, utilizing electrochemical principles to create an anode oxidation reaction environment and a cathode reduction reaction environment in the electrolysis reaction chamber, allowing scale to precipitate on the cathode surface, and using an electric scraper to automatically remove scale from the cathode surface. Without using any chemical agents, free chlorine, ozone and other disinfectants are generated online in the anode area to kill microorganisms, prevent microbial contamination including Legionella, and inhibit corrosion.

2、 Cathodic chemical reaction

At the cathode, a high concentration of hydroxide ions is formed: 2H2O+2e à H2+2OH -. This elevated pH environment (pH approximately 13) allows minerals that are prone to scaling to pre scale. Mainly used to remove calcium and magnesium ions from water.

CO2 + OH- à HCO3- ，HCO3-+ OH- à CO32- +H20,

OH -, CO32- and Ca2+form calcium hydroxide Ca (OH) 2 (scale) and calcium carbonate CaCO3 (scale).

3、 Anodic chemical reaction

In the anode region, the current converts chloride ions in the water into a sterilizing agent, free chlorine: Cl -- e à Cl0, while generating ozone: O2+2HO --2e à O3, achieving the function of sterilizing and killing algae.

4、 Principle of Automatic Scratching and Cleaning

The scraper drive device, scraper, and drain valve work together to scrape off the scale and other deposits that have been pre deposited on the inner wall of the reaction chamber, and discharge them from the drain valve. The automatic descaling action runs automatically, with one or more operations per day.
