EC data to estimate the operational cost of synthetic effluent for 30, 60, 90, and 120 minutes using a current (i) of 3.0 A and supporting electrolyte (ES) of 0.200 mol L−1, and for the mining effluent, for 90 minutes, using 3.0 A of current and 0.400 mol L−1 of supporting electrolyte.

| Synthetic | 30 | 12.6 | 3.0 | 4.0 | 68.00 | 4.725 | 0.503 |
| Synthetic | 60 | 12.5 | 3.0 | 4.0 | 68.00 | 9.375 | 1.006 |
| Synthetic | 90 | 11.7 | 3.0 | 4.0 | 68.00 | 13.162 | 1.510 |
| Synthetic | 120 | 12.8 | 3.0 | 4.0 | 68.00 | 19.200 | 2.013 |
| Mining | 90 | 3.5 | 3.0 | 4.0 | 29.80 | 3.937 | 1.510 |
