Among the ions found in raw water, calcium (Ca 2+) and magnesium (Mg 2+) ions are the most common causes of probing in known and water-using industries. These ions affect the quality of the products in textile and chemical industry, machine industry, surface and heat treatment baths in negative direction. In addition, water softening systems are widely used for industrial and domestic purposes as they cause problems in heating-cooling systems, steam boilers, circulation systems and pipelines.\r\nRegeneration of ion exchange resins used in water softening systems is divided into direct current and reverse current. In particular, reverse current regeneration system is used to soften water with high hardness. Because in this system both hardness is avoided and salt and water consumption is reduced.
