Titanium Electrode For Water Descaling

Scale, also referred to as limescale, is most often a problem in water-using equipment when water is heated. During the long-term operation of circulating water, hard water scale forms thick deposits in chilled water systems, consequently decreasing heat transfer, reducing water flow, and drawing extra energy. As is known to all, water descaling is a key procedure in commercial facilities maintenance, especially for cooling tower, condenser, heat exchanger, boiler.

As an non-corrosive solution, the electrolytic descaling has be exploited by more and more industries in recent years. Scale removal is achieved through the electrochemical reaction of water electrolysis. During the electrolysis process, the cathode undergoes a hydrogen evolution reaction to generate hydroxide radicals (OH−), creating a high pH environment. Heavy metal ions, such as calcium and magnesium ions, are precipitated onto electrode surface. At the same time, oxidizing substances fromed at the anode side have a certain effect on algae and fungi in the water, thereby inhibiting the growth of bacteria and preventing the adhesion of biological slime.
