Table 2.
The descriptive statistics concerning the results obtained for both seawater and reconstituted seawater at different treatment times (0–90 min).

| 10 | 4.8233 | 4.8299 | 4.8445 | 4.8438 | 4.8584 | 4.8629 | |

| 90 | 4.6430 | 4.6503 | 4.6622 | 4.6621 | 4.6739 | 4.6808 |
Each comparison was made by a non-parametric statistical test (Kruskal–Wallis test), which represented the most appropriate choice in relation to the small sample size and the characteristics inherent to the data itself (normality and variance distribution).
