Resin for water treatment is a synthetic material used in water purification processes, particularly in ion exchange systems. These resins are small, porous beads that attract and hold specific ions, such as calcium and magnesium, which are responsible for water hardness. When hard water passes through the resin, these ions are exchanged for sodium or potassium ions, resulting in softened water. Resins are also used for removing contaminants like heavy metals and nitrates, making water safe for consumption and industrial use.
