“…The more deposits that bind, the wider the closed cathode surface, which inhibits OHproduction. If the amount of OHgenerated is reduced, the binding of Al 3+ to form a coagulant is reduced, resulting in a drop in the percentage of organic compounds removed [55,56].…”

All This study compares the effectiveness of well-water treatment with coagulation, electrocoagulation, and electrocoagulation-coagulation methods in Kubu Raya, West Kalimantan, following the quality standards of the Minister of Health Regulation No. 32 of 2017. This study used an alum and was varied by testing the parameters of turbidity, color, TDS, Fe, Mn, and pH. The study results on the mass variation of alum showed an increase in pH, and increases in TDS, color, turbidity, Fe, and Mn. With the electrocoagulation method, the efficiency results of increased pH were 3.88%, 22.22%, 32.77%, and 42.59%; decrease in TDS 46.34%, 54.07%, 86.79%, and 114.75%; color reduction 95.39%; 28.85%; 88.79%; and 80.02%; decreased in turbidity 99.45%; 99.80%; 99.32%; and 99.10%; decreased Fe concentration 96.60%; 98.99; 96.20%; and 96.99%; and decreased concentration of Mn 99.59%; 99.75%; 99.72%; and 99.75%. Processing with the electrocoagulation method with the addition of 0.5 g alum resulted in a decrease in pH of -29.62%; -26.29%; 13.33; and 15.37%; decrease in TDS of 24.92%; 24.23%; 21.356%; and 16.59%; decreased in watercolor 86.09%; 74.27%; 91.24; and 70.02%; decreased in turbidity value 99.44%; 99.31%; 99.54%; and 98.96%; decreased Fe concentration 97.98%; 96.48%; 97.11; and 98.22%, and a decrease in Mn concentration of 99.75%; 99.55%; 99.75%; and 99.75%.

The demand for rhizoremediation technology that can minimize greenhouse gas emissions while effectively removing pollutants in order to mitigate climate change has increased. The inoculation effect of N2O-reducing Pseudomonas sp. TF716 on N2O emissions and on remediation performance during the rhizoremediation of diesel-contaminated soil planted with tall fescue (Festuca arundinacea) or maize (Zea mays) was investigated. Pseudomonas sp. TF716 was isolated from the rhizosphere soil of tall fescue. The maximum N2O reduction rate of TF716 was 18.9 mmol N2O g dry cells−1 h−1, which is superior to the rates for previously reported Pseudomonas spp. When Pseudomonas sp. TF716 was added to diesel-contaminated soil planted with tall fescue, the soil N2O-reduction potential was 2.88 times higher than that of soil with no inoculation during the initial period (0–19 d), and 1.08–1.13 times higher thereafter. However, there was no enhancement in the N2O-reduction potential for the soil planted with maize following inoculation with strain TF716. In addition, TF716 inoculation did not significantly affect diesel degradation during rhizoremediation, suggesting that the activity of those microorganisms involved in diesel degradation was unaffected by TF716 treatment. Analysis of the dynamics of the bacterial genera associated with N2O reduction showed that Pseudomonas had the highest relative abundance during the rhizoremediation of diesel-contaminated soil planted with tall fescue and treated with strain TF716. Overall, these results suggest that N2O emissions during the rhizoremediation of diesel-contaminated soil using tall fescue can be reduced with the addition of Pseudomonas sp. TF716.
