The effect of ,conductivity, of the ,wastewater, was investigated by adjusting the concentration of NaCl in the sample. The minimum and maximum salt concentrations employed were 2 and 8 g/L, respectively, corresponding to measured ,wastewater, conductivities of 7.44 and 13.75 mS/cm. Figure 4 shows the average time-dependent removal efficiency at each NaCl concentration.
