It is the process through which the water is relieved from hardness caused by calcium and magnesium ions using cationic resin. Hard waters create lime Stones especially in steam furnaces and hot water mechanisms which narrow their cross-sections and generate huge heat transfer losses and energy consumption. Softening systems are used so that mechanisms and heater-devices are protected against liming and that your water earns a good taste and softness. All control valves used in softening systems perform services, regeneration and reverse washing processes automatically. Quartsi di-vinyl benzene based resin is used in the system.
