单级软水器
　　当含有硬度离子的原水通过交换罐体内钠型树脂时，水中Ca2+, Mg2+被树脂中的 Na+ 交换吸附，去掉Ca2+, Mg2+除去碳酸盐或非碳酸盐硬度，即为软化水。当树脂吸附能力一定量的Ca2+, Mg2+之后，就必须进行再生，再生就是用盐箱中的盐水冲洗树脂层。盐水中的Na+ 把树脂上的硬度离子再置换到水中， 随再生液排出罐外，恢复树脂交换能力，继续软化制水。
　　功 能：以Na+ 置换吸附Ca2+, Mg2+离子，降低水质硬度。
　　用 途：锅炉用水软化，反渗透工艺进水预处理，硬度过高饮料用水，饮用水软化。
　　规 格：滤量1t/h-15t/h系列，超过15t/h以上者采用并联方式解决。
　　When raw water with rigid ion passing sodion resin in the exchanging cylinder, Ca2+, Mg2+ in water is exchanged and absorbed by Na+ in resin, wiping off Ca2+, Mg2+ and carbonate or non carbonate rigidity, is called softened water. The resin must be regenerated after absorbing some Na+ , Mg2+，regeneration is washing resin layer using brine in salt box. Na+ in salt water exchange the rigid ion of resin into water, then discharged with regeneration liquid off the cylinder, recovering exchanging capacity, and continuously softening water.
　　Functions：
　　Using Na+ to exchange and absorb Na+ , Mg2+，reduce water hardness.
　　Usages:
　　Boiler water softening, RO inlet water pre-treatment, high-hardness beverage water, drinking water transmission.
　　Specification:
　　Disposing flow rate is from 1t/h-15t/h, greater than 1t/h-15t/h, can be solved by parallel connection.
