The slow speed decarbonization is a process in which the chemicals

such as FeCl3

and lime milk etc.

are put into water

and the carbonate hardness in water being reduced through coagulation and precipitation etc..The application practice in one power plant shows that the adoptation of said slow speed decarbonization technology in treatment of make-up water for the circulating water can make the alkalinity and calcium hardness in water to be greatly recuced

thereby the enrichment factor can be enhanced by a big margin

achieving the goal of water-saving.
