工作程序
1、 供水：未处理的水通过树脂层，发生交换反应，产生软水。
2、 反洗：水从树脂层下部进入，松动树脂，去除细碎杂物。
3、 进盐水再生：利用较高浓度的盐水(Nacl)流过树脂，将失效树脂重新还原为钠型可用树脂。
4、 冲洗：按照供水时的流程使水通过树脂冲洗掉多余的盐液和再生交换下来的钙、镁离子。
5、 注水：向盐箱内注水，溶解食盐，以备下次再生所用。
钙的去除：
CaCO3+2Na-R=Ca-R+Na2CO3
Ca(HCO3)2+2Na-R=Ca-R+2NaHCO3
镁的去除：
MgCO3+2Na-R=Mg-R+Na2CO3
Mg(HCO3)2+2Na-R=Mg-R+2NaHCO3
 
Working procedure
 
1. Water supply: the untreated water passes through the resin layer to produce exchange reaction and soft water.
 
2. Backwashing: water enters from the lower part of the resin layer to loosen the resin and remove the fine debris.
 
3. Feed brine regeneration: use high concentration of brine (NaCl) to flow through the resin, and restore the failed resin to sodium type available resin.
 
4. Flushing: according to the process of water supply, make the water wash away the excess salt liquid and the regenerated calcium and magnesium ions through the resin.
 
5. Water injection: inject water into the salt tank to dissolve salt for next regeneration.
