Summary: This study analyzed the potential for the reuse of produced water (PW) in the I-WEST region. Treatment methods were selected based on PW composition and water standards, and the potential reuse of PW samples from different basins was assessed. The results showed that low-salinity PW is suitable for agricultural use, while high-salinity PW is more suitable for hydraulic fracturing. The reuse of PW can alleviate water scarcity in the I-WEST region.

Summary: Pressure-retarded osmosis (PRO) is a membrane technology that shows promise in harnessing the osmotic energy of saline solutions, particularly in hypersaline solutions like produced water. The high fouling propensity of produced water poses a major challenge, but pretreatment of the water at varying degrees can significantly reduce fouling rates in membrane systems. Comparing different membrane configurations, hollow fiber (HF) modules show lower fouling rates in PRO applications, making them more suitable for high-salinity water treatment.

Summary: DC power is more energy-efficient than AC power for EHD drying, with benefits such as enhanced drying rate and lower specific energy consumption. The specific energy consumption of a 2 x 2 discharge electrode is consistently smaller than the 1 x 1 one, indicating the importance of emitter spacing in process efficiency.

Summary: In this study, we evaluated the removal of toxic metals from high saline waters using dolomite filters. The results showed that the salinity had a significant impact on the removal of Sr and Ba, but a mild impact on the removal of Cd. The increase of pH due to dolomite dissolution enhanced the removal of Cd more significantly. The formation of guar-gum complexes attenuated the removal of Sr, Ba, and Cd by dolomite filtration, with a greater effect on Cd. The affinity sequence for the sorption of toxic metals was Pb > Cd > As > Ba > Sr at the salinity levels studied.

Summary: The paper investigates the potential of direct current- and alternating current-driven electrospinning in various linear aliphatic polyamides. Different concentrations of polyamides are dissolved and spun using high voltage, and the resulting nanofiber layers are analyzed for defects, diameter, dynamic viscosity, and conductivity. The most suitable concentrations are determined and spun at a larger scale, and the surface energy of the fiber layers is measured for selecting a suitable polyamide for a specific application.

Summary: The review summarized the research progress of bioelectrochemical systems (BES) in treating produced water, with a critical analysis of the parameters influencing BES performance. Inoculum, temperature, hydraulic retention time, external resistance, and the use of real or synthetic produced water were found to significantly impact BES performance. The use of real produced water as feed in experiments is highly recommended for better application of BES technology.

Summary: Measurements were conducted to investigate the growth rate of the return current instability, which was found to be consistent with nonlocal transport. The maximum growth rate of 5.1 x 10^9 Hz obtained through Thomson scattering was three times lower than the prediction of the classical Spitzer-Harm theory. The measured plasma conditions suggested the presence of nonlocal heat flux, and Vlasov-Fokker-Planck simulations considering nonlocality were able to reproduce the observed growth rates. Furthermore, the measured threshold for the return current instability agreed well with previous theoretical models.

Summary: In this study, drilling fluid formulations were developed using a four-level factorial design to evaluate the effect of drilling fluid components on their rheological properties and in the loss of circulation. The incorporation of LCMs improved the rheological properties of the drilling fluid, with CMC, BT, and HG being the main factors in combating loss of circulation in the fracture and filtration phases. Additionally, the interaction of HG*CMC and BT*CMC was found to be highly significant in preventing loss of circulation.

Summary: By utilizing the metabolic versatility of microalgae, high concentrations of ammoniacal nitrogen in agro-industrial effluents and livestock wastes can be transformed into valuable products. However, the toxicity of ammoniacal nitrogen to microalgae poses a challenge. In this study, the authors evaluated three strategies, including finding suitable cyanobacteria species, optimizing cultivation conditions, and conducting fed-batch bioprocess. They successfully achieved high removal efficiency of ammoniacal nitrogen and increased production of useful compounds.

Summary: Polymeric plastic materials have led to significant advancements in industry, but their production and consumption also generate large amounts of waste, causing severe environmental impact. Pyrolysis processes offer a solution by converting these wastes into valuable fuels and raw materials. The use of catalysts, such as zeolites and clays, enhances selectivity and product distribution, resulting in a more sustainable process. Modifications to the structure of these catalysts further improve performance and reduce the formation of harmful polycyclic aromatic hydrocarbons (PAHs).

Summary: This work investigates the characterization and leaching studies of pre-salt drill cuttings from offshore oil and gas exploration in ultradeep waters. The highest concentrations of Fe, Al, and Ba were found in the drill cuttings. Non-aqueous fluids contributed to the significant contents of Ba, Al, Fe, Cu, Pb, Mn, Si, and Zn, while aqueous fluids resulted in high concentrations of Ni and Cr. The samples showed different levels of total petroleum hydrocarbons (TPHs) content, and some cutting samples were contaminated with oil. Most samples were contaminated by polycyclic aromatic hydrocarbons (PAHs). Saline and aqueous leachates contained different metals in varying concentrations.

Summary: Among global efforts facing plastic pollution, the gradual replacement of plastic with alternative materials has become increasingly important. However, consumers' unfamiliarity with biodegradability concepts leads to misguided decisions, while greenwashing practices by stores and manufacturers worsen the situation. Additionally, the lack of certification standards and regulatory frameworks for alternative materials presents challenges for their governance.

Summary: This study aimed to assess sediment contamination by different pollutants in coastal and marine environments at Rio de Janeiro, Brazil. The results showed environmental differences between coastal lagoon and oceanic beaches, mostly influenced by marine waters, while sediment characteristics largely varied among bay's beaches. PAHs and BPA were not detected, but PAEs were found for the first time in the sediments of Rio de Janeiro coast. DEHP was detected in all environments, DBP in coastal lagoon and three marine environments, and DnOP and DINP solely in the coastal lagoon.
