Summary: Nanoplastics have become a significant environmental concern due to their adverse effects on water environments. Wastewater treatment plants are identified as major sources of nanoparticle generation, primarily through the mechanism of cracking larger plastic debris. Current membrane processes are ineffective for nanoparticle removal, leading to the need for developing a bio-nanofiltration process as an alternative method. This process can produce nanoparticle-free water for safe discharge.

Summary: This research introduces a digital twin method to simulate the coordinated operation of energy flexibility resources in wastewater resource recovery facilities. Results show a reduction in electricity bills of 17% and an annualized return on investment of 3% in a California facility. However, new energy flexibility investments are less profitable without time-of-use incentives and existing cogeneration facilities. Overall, the findings suggest the need for policies and subsidies to incentivize the sector's energy flexibility. Rating: 8/10.

Summary: In this study, the distribution and fate of microplastics in different water sources and treatment plants in France were investigated. Wastewater was found to contain the highest concentrations of microplastics, followed by surface water/groundwater and seawater. Polyethylene was the most common type of microplastic, followed by polypropylene, polystyrene, and polyethylene terephthalate. Most treatment technologies were effective in removing microplastics, although some processes or pipes could introduce additional contamination. Ultrafiltration was confirmed to be an effective technology for microplastic retention and size control.

Summary: An ingenious and unassisted solar-driven wastewater resourcezation system (SDWRS) was designed by connecting a silicon cell (SC) to the back of a bismuth-doped TiO2 nanorod array (BTNR) for efficient water treatment accompanying hydrogen and electricity generation. With the doping of Bi, the charge transfer property and donor density of the BTNR were effectively improved. The introduction of SC provided a higher inner bias than conventional photocatalytic fuel cells (PFCs) to drive efficient electron transfer, resulting in enhanced light utilization and charge transfer.

Summary: This paper proposes a grey box model for fuel consumption prediction of wing-diesel hybrid vessels based on feature construction. By using both parallel and series grey box modeling methods and six machine learning algorithms, twelve combinations of prediction models are established. A feature construction method based on the aerodynamic performance of the wing and the energy relationship of the hybrid system is introduced. The best combination is obtained by considering the root mean square error, and it shows improved accuracy compared to the white box model. The proposed grey box model can accurately predict the daily fuel consumption of wing-diesel hybrid vessels, contributing to operational optimization and the greenization and decarbonization of the shipping industry.
