Duplex Water Softening process is materialized by ion changing method. Ion change is materialized by passing water with Ca and Mg that causes hardening through Na form cationic resin. While firm water pass through sodium based cationic resin, hardening ions inside (Ca+2 and Mg+2) change place with Na tied to resin. DWS unite consist of two softening unit. System can be controlled as volume metric as per the volume of water that passes. Each softening device do regeneration period in turn order and when it becomes ready, wait for saturation of process unit and wait for handover of process. By this way, soft water is produced constantly 24 hours a day without need of human interference and without stopping of process for regeneration operation. After certain amount of firm water pass through resin media, resin particles are completely covered with hardening minerals. At this case, joining of hardness minerals end. To be able to remain at water hardness ions, resin particles must be rid of from hardness minerals, again sodium particles must be tied. This process is called Regeneration. Regeneration process consist of 5 main steps that are back-wash, salt water absorption, slow rinsing, fast rinsing and salty water filling. As a result of conclusion of 5 steps, while resin, calcium (Ca2 + ) and Magnesium (Mg2 + ) leaves their ions, sodium (Na+) again combines ions to itself and be ready to service position. When design of DWS unites are made, resin quantity which will be placed inside resin tank is calculated according to raw water characteristic, average daily flow and peak flow consumption.
