Summary: This study evaluated the effect of alternative filtering materials and bed aeration on the retention of nutrients and fecal bacteria in woodchip bedded stand-off pads for cows. 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: This study focuses on the development of an air-lift bio-electrochemical reactor (ALBER) with a continuous feeding regime to enhance nitrogen removal from synthetic wastewater. The effect of temperature, hydraulic retention time (HRT), N -NH+4 /TN ratio, and current density on the reactor performance was investigated, and the ALBER achieved a maximum TN removal of 73%. The results suggest that the ALBER has potential for treating industrial wastewater at low temperatures.

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.
