“…In an earlier study, only 62% hydrocarbon removal was observed when applying FTWs vegetated with Vetiverria zizanioides. 6 Our findings suggest that augmenting FTWs with a specific hydrocarbon-degrading bacterial consortium improves the traditional phytoremediation system by enhancing the capability of both plants and microbes to degrade recalcitrant compounds. This plant-bacterial synergism for hydrocarbon degradation in water has been reported in earlier studies.…”

“…Crude oil consists of various proportions of different hydrocarbons, such as alkanes, aromatics, and polycyclic aromatic hydrocarbons, as well as non-hydrocarbons, including sulfur, nitrogen, and trace metals, particularly nickel, iron, and copper. 5,6 Human exposure to hydrocarbons occurs primarily through skin contact and consumption of contaminated food and water. 7 Some hydrocarbons are reported to be carcinogenic, neurotoxic, and genotoxic to humans and other organisms in the environment.…”

The contamination of water with hydrocarbons resulting from oil exploration and production highlights the need for efficient and environmentally friendly technology to mitigate this form of water pollution. Floating treatment wetlands are a sustainable approach for remediating contaminated water. In this large-scale study, we used four different plants, Phragmites australis, Typha domingensis, Leptochloa fusca, and Brachiaria mutica, to vegetate a floating mat with an area of 3058 m 2 made from locally sourced materials. The floating treatment wetlands constructed in this manner were used to treat an oil-contaminated water stabilization pit resulting from oil and gas exploration activities in District Chakwal, Pakistan. The plants and the water in the pit were inoculated with a consortium of 10 different hydrocarbon-degrading bacteria. The application of floating treatment wetlands to the pit reduced chemical oxygen demand, biochemical oxygen demand, total dissolved solids, hydrocarbon content, and heavy metals by 97.4%, 98.9%, 82.4%, 99.1%, and 80%, respectively, within 18 months. All plants survived and showed growth, but maximum development and biomass production were exhibited by P. australis. Moreover, the bacteria used for inoculation were able to persist and show degradation activity in the water as well as in the rhizoplane, roots, and shoots of the plants. We conclude that floating treatment wetlands can be applied to oil-contaminated water stabilization pits for affordable and effective water treatment.

“…RSM is a set of mathematical and statistical techniques to analyze the response in which some independent variables influence the dependent variables and the ultimate goal to optimize the response in various research topics [21]. RSM has been widely used in analyzing various water treatment experiments [4,[22][23][24][25][26][27][28][29][30][31][32][33].…”

Liquid waste of tofu production has a high content of organic matter which can lead to a decrease in water quality. This study was aimed to obtain an optimal combination of duration and waste concentration in tofu liquid waste treatment using Chrysopogon zizanioides. Response surface method using Design Expert 7.0 software was applied to optimize combination response of duration (3, 9, 15 days) and waste concentration (20, 40, 60%), aided by Design Expert 7.0 software. The optimum treatment was 15 days with 20% waste concentration, reducing 55.48% of COD, 37.86% BOD, 93.51% TSS, 87.86% Turbidity, increasing DO to 7.2 mg/L and pH to 7.2.

“…There is an increasing number of studies that evaluate the use of plants in the petroleum contaminated freshwater areas and in these researches different plant species such as Landoltia punctata (Ertekin et al, 2015), Vetiveria zizanioides (Effendi et al, 2017) and Lemna minor (Wang et al, 2017) have been used. Azolla has a special significance between the freshwater plants used in phytoremediation.…”

<p>In this study, the potential use of Azolla filiculoides Lam. for the bioremediative solution to polycyclic aromatic hydrocarbon (PAH) pollution due to crude oil spills in freshwater was investigated. The plants were grown in nitrogen-free Hoagland nutrient solution media containing 0.05%, 0.1%, 0.2%, 0.3%, 0.4% and 0.5% crude oil by volume for 15 days under greenhouse conditions. Relative growth rates of A. filiculoides decreased in the presence of crude oil in a concentration-dependent manner. The probable influence of A. filiculoides on the biodegradation of polycyclic aromatic hydrocarbons was measured by using synchronous UV fluorescence spectroscopy. GC-MS analysis were also carried out to elucidate the behavior of the oil in experimental and control samples. Although 1-2 rings PAHs have not been encountered in control or plant samples, the measured intensity for 3-4 ring PAHs in plant samples was remarkably lower in comparison to the control. Furthermore, these results demonstrated that the predominant efficacy of the A. filiculoides was for 3-4 ring PAHs at the range 0.05 to 0.2% crude oil concentrations. It could be concluded that the bioremediative potential of A. filiculoides for the removal of polycyclic aromatic hydrocarbons strongly depends on the amount of oil in the contaminated water resource. In other words, A. filiculoides could be used more effectively after the removal of excess crude oil in the spilled freshwater areas.</p>
