Summary: This study investigated the effect of dissolved oxygen concentration on the production of storage compounds by Alcanivorax borkumensis SK2. It was found that the variation in DO concentration can influence the bacterial metabolism pathway, leading to different types of produced compounds. The results show that selecting the appropriate DO concentration during PW treatment can enhance the production rate of valuable compounds while maintaining high efficiency of hydrocarbon removal.

Summary: The study found that once BAC filters reach a steady state, GAC adsorption still plays a major role in removing organic matter due to bioregeneration. Iodine value can be used as an indicator of BAC performance in the initial stages, dominated by adsorption, but not in later stages. Pore-size distribution characteristics may be a better indicator, representing both adsorption performance and microbial activity.

Summary: This study investigates the use of hydrocarbon-metabolising organism Alcanivorax borkumensis SK2 as a solid phase in a bubble column reactor (BCR) and the effect on hydrodynamics. The results show that superficial gas velocity (U-G) is the most significant parameter, with gas holdup increasing linearly with U-G. The addition of hydrocarbons into the system resulted in a significant increase in gas holdup, particularly at high U-G. SK2 addition reduced fluid surface tension and increased gas holdup in the BCR.

Summary: The search for effective and cost-efficient adsorbents for PFAS contamination has led to the evaluation of a novel surface modified organoclay (SMC) adsorbent compared to granular activated carbon (GAC) and ion exchange resin (IX) for the treatment of different PFAS impaired waters. Results showed that IX exhibited the best performance in terms of adsorbent use rates and was more effective than GAC and SMC in treating PFOA from various water sources excluding groundwater. Cost analysis indicated that treatment of landfill leachate and membrane concentrate was more expensive than groundwaters or wastewaters.

Summary: The study conducted two laboratory tests to verify the suitability of Italian commercial biochar as an adsorbing material for arsenic in groundwater. While the results aligned with previous literature, they also showed that using a large amount of biochar does not necessarily improve efficiency. Additionally, factors such as the origin and grain size of the biochar can affect the efficiency of adsorption.

Summary: Microalgae and cyanobacteria are valuable resources for producing biofuels/bioenergy, biomaterials, and biochemicals. Although microalgal systems can involve waste stream valorization and green chemistry, their sustainability is uncertain, hindering their large-scale application. Life cycle assessments (LCAs) based on primary data for microalgal pilot to industrial-scale plants are lacking uniformity and transparency. The review identified electricity consumption and infrastructure as major hotspots, and recommended the use of renewable energy and sunlight for biomass photosynthesis. Upstream processes and suitable reactors, locations, and harvesting methods also impact the environmental profile. Biofuels are not competitive, but multi-product biorefinery scenarios show promise. Co-product valorization, waste stream utilization, renewable energy deployment, and compound productivity need enhancement for high-value microalgal compounds. More LCA studies on large-scale plants, particularly integrated biorefinery concepts, are required for sustainable commercial systems.

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.
