Principles of electrochemical water treatment technology
The main principle of electrochemical water treatment technology is to use the electrochemical redox reaction of titanium electrodes to adsorb Ca2+ and Mg2+ in the water to the cathode in solid form and then remove them, thereby reducing the hardness of the water body and producing some strong oxidizing substances to inhibit the cooling cycle. The growth of fungi and algae in the water system achieves the function of sterilization and algae removal.
Principle of electrochemical descaling
Under the action of electric current, water undergoes an electrolysis reaction at the cathode to generate hydroxide ions. The hydroxide ions generated by the cathode reaction break the balance of alkalinity and hardness in the solution near the cathode. At the same time, the calcium and magnesium plasma in the water are ionized under the action of the electric field. Migrating to the cathode area, calcium carbonate and magnesium hydroxide are precipitated and precipitated respectively. At the same time, under the action of the electric field, calcium carbonate crystallizes on the surface of the cathode plate and is easy to peel off and remove.
Principle of electrochemical sterilization
Electrochemistry is not a simple process. It includes a variety of action mechanisms and reaction processes such as physics, chemistry, and biology. It can be considered to be completed by the joint action of multiple factors. Under the action of an electric field, chlorine ions in the water will be oxidized into free chlorine components such as chlorine gas, hypochlorous acid, and hypochlorite. Electrolytic chlorination mainly works through hypochlorous acid. Hypochlorous acid is a small neutral molecule that can oxidize and destroy bacteria, causing them to die. In the electrocatalytic reaction, some short-lived intermediate products are generated on the electrode surface through electrolysis of water and oxygen dissolved in the water. These strongly oxidizing substances can oxidize various components in the microbial cells, thereby causing irreversible changes in the microorganisms. And death.
