Summary: In this study, the simultaneous removal of PNP and NO3- was investigated under autotrophic and heterotrophic denitrifying conditions. The results showed that autotrophic denitrification with elemental sulfur can efficiently eliminate both PNP and NO3-, even at high concentrations. ORP was identified as a possible control parameter to modulate PNP removal efficiency. Additionally, the autotrophic column showed better resiliency compared to the heterotrophic one.

Summary: In this study, the effectiveness of nitrate-dependent ferrous iron oxidation for simultaneous removal of nitrate and heavy metals was investigated. Successful removal of nitrate, iron, and zinc was achieved under certain conditions, but the performance decreased significantly when using coke-oven wastewater, suggesting the need for mixed culture of NDFO bacteria and thiocyanate/organic-degrading denitriflers to improve reactor performance.

Summary: A study in Southeast China reveals that the transition zone between rivers and riparian aquifers plays a crucial role in removing nitrate contamination from aquatic systems. The high connectivity between rivers and groundwater enhances the potential for nitrate removal. The study also highlights the significant contributions of manure and sewage, as well as soil and chemical fertilizers, to nitrate contamination.

Summary: The performance of nitrate removal by Pseudomonas mendocina GL6 cells immobilized on bamboo biochar was superior to that of free cells, with higher nitrate removal rate and capacity. Immobilized cells fitting well to zero-order kinetics model displayed increased efficiency in nitrate removal under various conditions, likely due to the protective effect of biochar carrier and enhanced expression levels of denitrification functional genes and electron transfer genes. Biochar-immobilized P. mendocina GL6 has great potential for removing nitrate from wastewater via aerobic denitrification.

Summary: Woodchip bioreactors are used to remove nitrate from agricultural drainage water through microbial processes, primarily heterotrophic denitrification. Microbiomes in these bioreactors are dominated by Proteobacteria, especially Pseudomonas, along with other functional groups such as lignocellulose degrading fungi and dissimilatory sulfate reducers. The high species diversity and similarity in microbiomes between bioreactors suggest that the woodchip resource niche plays a significant role in shaping the microbial community.

Summary: This study investigates the impact of macropores on freshwater-saltwater mixing and terrestrial solute transport using laboratory-scale experiments and numerical modeling. The results show that macropores modify groundwater flow dynamics, leading to larger mixing zones and increased removal of nitrate. These findings have important implications for coastal ecosystem protection and reducing nitrate fluxes.

Summary: Increased mariculture activities globally have led to elevated nitrogen compound levels and intensified accumulation of antibiotics. The study focused on the impact of sulfamethoxazole (SMX) on nitrate removal in mariculture wastewater. It was found that nitrification was not inhibited by SMX, but aerobic denitrification was. Proteobacteria, particularly Comamonas, Acinetobacter, and Thauera, were efficient in COD removal and SMX degradation.

Summary: Textile industry generates a large amount of wastewater with various polluting substances. Water reuse, especially with the combination of reverse osmosis and membrane bioreactor treatment, has become more common in this industry. In this study, the performance of an autotrophic sulfur-based denitrifying column was evaluated for the reduction of nitrate in the permeate of a lab-scale membrane bioreactor receiving real textile wastewater, as well as in the concentrate stream of a real-scale reverse osmosis plant used for water recovery from textile wastewater. The results showed that the sulfur-based column could achieve high denitrification performances for both the membrane bioreactor effluent and the reverse osmosis concentrate.

Summary: This study demonstrated the successful removal of high nitrate concentrations from groundwater using a novel pressurized hydrogenotrophic denitrification reactor, while preventing nitrogen gas accumulation in the reactor's headspace. By connecting the main reactor to an external degassing unit and implementing liquid recirculation, steady-state nitrogen and hydrogen gas partial pressures were maintained, achieving nitrate removal rates over 97% with denitrifying rates up to 6 g N/L-reactor/d under both freshwater and brine conditions. The dynamic conditions in the reactor system led to reduced external recirculation flow requirements and greater than expected hydrogen utilization rates of over 93%.

Summary: Integrated buffer zones (IBZ) are effective in reducing nitrogen loading from agricultural fields to streams by providing a favorable environment for denitrification. However, there is a risk of increasing emissions of greenhouse gases nitrous oxide (N2O) and methane (CH4). The study found that IBZs can efficiently remove nitrogen while also emitting greenhouse gases, but the emissions are comparable to those of natural wetlands and other mitigation measures.

Summary: This study demonstrates the coexistence of denitrification, DNRA, and anammox processes in a highly saline lake, with their contribution determined by environmental conditions such as oxygen and light. DNRA, especially denitrification to N2O, were the dominant nitrogen removal pathways in the presence of oxygen and/or light. Conversely, anoxia and darkness promoted NO3- reduction by DNRA combined with N loss by anammox.

Summary: Phosphonium-based ionic liquid immobilised in polysulfone capsules prepared by the phase inversion technique showed potential for adsorbing various phenolic compounds, with a successful immobilisation rate of 63.29%. The capsules demonstrated efficient removal of phenolic compounds, especially 2,4-dichlorophenol, under different pH conditions, temperature variations, and salt concentrations, showing promise for real effluent treatment. Adsorption kinetics indicated a second-order mechanism with intraparticle diffusion as the limiting factor, and the Redlich-Peterson model best fit the experimental data with a q(max) of 404.50 mg.g(-1), suggesting these capsules have potential for environmental pollution treatment caused by phenolic compounds.

Summary: Textile dyeing processes generate aqueous effluents containing toxic dyes, which require new wastewater treatment processes. This study evaluated the use of an Ionic Liquid for Liquid-Liquid Extraction to extract and treat reactive dyes, showing high extraction yields for black, navy, and royal dyes. However, the extracted solution exhibited increased toxicity towards Daphnia magna due to traces of the Ionic Liquid. Further studies are needed to reduce the risk of toxicity transfer to water.

The results showed that the alternative biofilters were more efficient in removing COD, SS, TN, and NO3-N, while conventional biofilters were more efficient for PO4-P removal. Aeration did not have a significant effect under the tested temperature conditions.

Summary: This study evaluates the performance of ozonation and adsorption as in-series processes compared to standalone processes for the removal of Contaminants of Emerging Concern (CECs) in drinking water. The combination of both processes proves to be more effective than adsorption and ozonation alone. Ozonation improves the adsorption performance of poorly-oxidizable CECs but worsens that of well-oxidizable compounds. This research highlights the importance of considering both processes in the removal of CECs in drinking water treatment plants.

Summary: The exacerbation of global warming, extreme weather events, and rapid urbanization have led to increased flooding in urban areas. China has adopted sponge city as an efficient means of preventing and controlling urban floods. Using a SWMM-FVCOM model, the hydrological reduction and control effect of sponge city construction (SPCC) within a university campus were evaluated. The study found that implementing SPCC effectively mitigates surface runoff and reduces the severity of urban flooding. However, the efficacy of runoff control decreases with longer rainfall return periods.
