An apparatus for evaporative concentration of treating water using hot lime softening and a method for evaporative concentration of treating water using thereof

摘要

The present invention relates to a technique for concentrating a water to be treated containing a hardness-inducing substance by evaporation, and more particularly, to a process for concentrating the water to be treated by evaporation through a first evaporator, a hot- To prevent scale formation and to reduce the operation cost by eliminating the need for a separate heat source for satisfying the operating temperature of the high-temperature water softening apparatus, and a method for concentrating the evaporation.
