In the above table, First Grade Na+ represents First Grade Na+
Exchanger. Second Grade Na+ represents Second Grade Na+
Exchanger.
 When the water turbidity exceeds the conditions, a filter should be
installed on the inlet of control valve.
 When the water hardness exceeds the conditions, the outlet water
hardness will hardly reach the requirement of boiler feed water（0.03
mmol/L）. It is suggested to adopt second grade softener.
