“…The formation of oxidants via electrochemical oxidation has been proposed as a feasible and efficient technique to treat hard-to-degrade pollutants in wastewater, standing out as a novel alternative due to its simplicity compared to other oxidation processes, particularly the use of low-cost electrode materials and their durability. To this concern, the capacity of electrochemically generated active chlorine to oxidize organic pollutants, and inactivate microorganisms has been demonstrated in several studies, [1][2][3] indicating that this process is a feasible technology. However, to achieve high-efficiency effluent treatments, the design and development of an optimized electrochemical reactor is required, which is not an easy task that might require a considerable amount of experimental data.…”

This study proposes a methodology to optimize the design of an electrochemical flow-by reactor to increase the active chlorine production. The performances of various reactor configurations were evaluated using Computational Fluid Dynamics, starting from the dimensions of the well-known FM01-LC reactor channel (B=4 cm, L= 16 cm, and S=1 cm), increasing or decreasing each component by 25%. These conditions were calculated using a Box-Behnken design of experiments, screening out the above dimensions as parameters in addition to the volumetric flow, which was operated at two different rates: 1 and 5 L min-1. A surface response methodology (RSM) was utilized to optimize the response variables, and determine the best design parameters. The combined computational study herein proposed suggests that the optimization of the flow electrochemical reactor design is a compromise between the flow uniform distribution, and mass transfer. It is found that the optimization method used is adequate at the experimental level, since the optimized channel (0.01M) presents better performance than the conventional FM01-LC channel (0.002 M), after 60 min of experimental electrolysis. It is expected the current analysis will contribute to the development of new filter-press-type electrochemical reactors optimizing chlorine production for numerous applications.

“…Therefore, the classification of contaminated areas into risk classes [80,81] and the selection of appropriate remediation measures are crucial for the restoration of these soils [82][83][84]. When choosing a remediation method, the type and extent of contamination, soil texture, size of the contaminated area, and its economic purpose use should be taken into account [85,86]. Therefore, the plants can play an invaluable role in mitigating potential hazards associated with the impact of petroleum-derived products [14,86,87].…”

Investigations into the effective, fast, and economically viable remediation of soils polluted with petroleum-derived products are still relevant. The vegetative pot experiment was conducted at the Didactic-Experimental Garden greenhouse (NE, Poland, 53.759° N, 20.452° E) on loamy sand (LS) and sandy loam (SL) soils. Its main research objective was to assess the effectiveness of biochar (B), halloysite (H) and alginite (A) in the biological regeneration of contaminated soil diesel oil (DO) and petrol (P). The assessment was conducted by determining the magnitude of the adverse impact of these xenobiotics on the growth and development of Zea mays, as well as the activity of seven soil enzymes. The impact of the tested contaminants and sorbents was assessed based on the impact factors (IF) of DO and P, as well as B, H, and A on Zea mays biomass and enzymatic activity of the soil. Soil contamination with petroleum-derived products disrupted the growth and development of Zea mays. DO had a stronger inhibitory effect on plant growth compared to P. Zea mays cultivated in LS, which was less resistant to the effects of these contaminants compared to that cultivated in SL. The impact of DO and P on enzyme activity depended on the soil texture. DO stimulated enzyme activity in LS and SL, while P only did so in LS. All remediation substances, and biochar in particular, led to an increase in plant biomass in the DO-contaminated soils. Both biochar, halloysite and alginite also improved the biochemical quality index (BA) of SL and LS. Despite the unquestionable remediation potential of the analyzed sorbents, their highest efficacy can only be achieved by their application on soils with physicochemical properties corresponding to their characteristics, which is a valuable guideline for further research.

“…It is important to note that the biodegradation of petroleum organic pollutants is a dynamic and intricate process that is influenced by various environmental factors, the composition of the pollutant mixture, and the diversity of microbial populations present at the contaminated site [21,22]. However, these changes remain unpredictable, especially in the subsurface environment, where contaminants and microbes are mutually influenced by groundwater, soil, and air, leading to a great challenge in determining their distribution and communities [23]. The main limitation of oil pollution evaluation is that analyzing the pollution process based solely on pollutant concentration may be insufficient and inconsistent, which may lead to uncertainty or even errors in the evaluation outcomes.…”

A quantitative and qualitative assessment using molecular markers derived from compound-specific indices for indicating groundwater impacted by petroleum spills in an oil field was recently undertaken and demonstrated serious contamination, with both high total petroleum hydrocarbons (TPH) (3.68–7.32 mg/L) and hazardous compounds in the groundwater. A petroleum source was identified, and the analysis revealed a decreasing trend of fresh petroleum input, along with groundwater advection and an increasing trend of biodegradation potential at locations farther from the source. This was confirmed via microbial analysis with both biodegrading microorganisms and diversity indices (Shannon, Simpson, and Pielou) and the principal component analysis (PCA) modeling approach, which classified the field samples into three types according to the distribution correlations between different organic compounds. Biodegradation was believed to be the dominant sink of hydrocarbons due to the increasing Pr/C17 and Ph/C18 values with seasonal changes. Raised temperatures activated the microbial degradation process; specifically, low-weight hydrocarbons degraded more rapidly than high-weight hydrocarbons, resulting in the accumulation of an unresolved complex mixture of bioproducts at locations that were farther away. Spatially, the Pr/C17 and Ph/C18 values increased from the upstream to the downstream areas, showing substantial biodegradation. The relationships between the molecular markers and chemical indices were quantified via canonical correlation analysis (CCA) to visually explain the interactive reaction processes. It was also demonstrated that the biodegradation of petroleum organics can be characterized by the consumption of dissolved oxygen and a decreasing Pr/Ph ratio, due to system reduction. These results demonstrate that compound-specific molecular markers, coupled with biochemical parameters, can effectively support a better understanding and effective fingerprinting of the fate and transport of petroleum organic contaminants, thus offering valuable technical support for a cost-effective remediation strategy.
