On the advantages and disadvantages of physical methods (high-frequency magnetic fields, microelectrolysis of low-molecular-weight water) and chemical agents in treating circulating water systems: What are the future development trends for industrial circulating water?

Physical method (electrochemical method): The vulvar electrode adsorbs calcium and magnesium cations to produce precipitates; The inner anode converts chloride ions into free chlorine, which adsorbs bacteria on the anode and kills them (the surface of bacteria is negatively charged) ; Scale inhibition: Generates a high-frequency magnetic field and micro-electrolysis, offering a wide range of treatment capabilities. During the special treatment process, the lattice of the formed scale is disrupted, turning it into soft scale. In a short period of time, small-molecule reduced water with a low reduction potential of -600 mV is generated; such water can reduce the surface tension of water, enhance its permeability and polarity, and increase the dipole moment of water molecules. This water has a strong dissolving effect on scale and rust, as well as the ability to reduce heavy metal ions, which are then absorbed by the reaction absorber. Corrosion prevention: Under the action of a high-frequency magnetic field, scale is controlled and removed; dissolved oxygen does not easily precipitate when combined with water molecules, thereby preventing corrosion caused by dissolved oxygen as well as corrosion that occurs beneath the scale, thus providing effective corrosion prevention. Sterilization: The electric current converts some of the chloride ions into chlorine gas; this chlorine gas dissolves in water to form hypochlorous acid, while oxygen radicals, hydroxyl radicals, and hydrogen peroxide are also produced. This series of products creates conditions for killing microorganisms; together with the ampere current and the locally high and low (anodic) pH levels, they maintain a disinfecting environment inside the electrochemical device.
