Summary: Understanding the behavior of heavy metals in wastewater is crucial for the development of metal removal and detection techniques. In this study, the dynamic and evolving size and partitioning behavior of lead, cadmium, and arsenite throughout the wastewater treatment train were characterized. Cd and As(III) were found to be highly mobile, while Pb was primarily in complex forms or adsorbed onto inorganic particulates. An increase in water hardness slightly increased metals in the dissolved fraction.

Summary: The high fat content in rendering wastewater requires primary treatment to remove floatable fats. The recovery of waste fats is an additional benefit from the primary treatment. Dissolved air flotation (DAF) is commonly used but has disadvantages. This study explores the use of electrocoagulation-electroflotation (EC-EF) as an alternative method. EC-EF shows better performance in COD removal and can concentrate and preserve long chain fatty acids. Higher current densities in the electrochemical cell generate surplus coagulants for further coagulation. Longer mixing duration in the post-EC-EF treatment step enhances overall COD removal.

Summary: Improper disposal of animal waste can cause environmental problems, but it can also be a valuable resource if properly managed. Recent studies have focused on recovering and reusing animal waste as an alternative to traditional processes. Nitrogen and phosphorus recovery, energy generation, high-value-added products, and water reuse are the main areas of research. Energy generation from livestock waste is a mature solution, but there are economic barriers and other potential routes for development.

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.
