This is a generic system that is applied in a food & beverage workshop that reaches a balance of cost & performance. The source water is from underground with TDS=800ppm, EC=400μS/m, hardness=450mg/L, so a softener tank was added to the system. The outlet water with TDS≤7ppm, EC≤3.5μS/m, and hardness≤50mg/L, which goes above the national standard.
