Optimization of Tap and underground water SAEW production system by combining 1.0 – 3.0 M KCl with 4 % HCl and its physicochemical properties.

Table 3 shows the different combinations, including HCl and KCl at different concentrations and flow rates to optimize the production process for SAEW. These combinations led to various EW production, including strongly acidic, acidic, and slightly acidic EWs. Increase in KCl concentration and electrolyte flow rate was caused increase in ACC and decrease in pH for all combinations. Except at 1.0 M KCl, SAEW was produced at the EFR between 1 and 2 mL/min for TW. However, SAEW was obtained with EFR at 1 mL/min for all combinations performed using UW.
