Synthesized soda ash was prepared by Solvay process with different molar ratio for application of water softening process. In urban utilization, water supply is very important for safe condition. In this research, Box Behnken experimental design was employed for optimization of soda ash. The maximum yield percent of 19.882 of soda ash was obtained by the reaction salt to ammonium hydroxide to carbon dioxide 1 3 6.8 during the reaction time 90 min. The synthesized soda ash was analyzed by X ray

Soda ash obtained from optimum condition was applied in water softening of tap water. According to the experimental results of water softening process, the maximum removal of hardness of water was observed at 3 ml of 10 lime solution with 20 ml of 5 of soda ash solution for 1000 ml of water. After treated the lime soda process, the total hardness of water was reduced to initial condition of 255 ppm to 24 ppm.
