Problems solved by technology

[0002] Natural water contains a large amount of calcium and magnesium ions. If the boiler directly uses raw water with calcium and magnesium ions, it will cause scaling on the boiler and seriously affect the safe and economical operation of the boiler. Therefore, the water for industrial boilers must be softened.
According to the relevant regulations of the national labor protection department, the hardness of the boiler inlet water must not be higher than the corresponding hardness index. The traditional chemical method is used to detect the water quality hardness of the inlet water. Sudden changes in water quality cannot be reflected in time, and the detection speed of this method is slow, and the consumption of chemical reagents is high. Therefore, it is difficult to ensure that the hardness of boiler water reaches the hardness index specified by the national labor protection department for a long time.
