Comparative study of lime softening, soda ash process, and
In this study, lime softening, soda ash process, and electrocoagulation (EC) are compared for their removal of hardness and dissolved salts (measured as conductivity) from groundwater. The hardness removal efficiencies by lime softening, soda ash process, and their combinations are 70.7, 33.3, and 86.7% respectively with the corresponding …
