There is growing interest in the development of more cost-effective and retrofit technologies for the upgrade and expansion of existing wastewater treatment plants with extreme space constraints,. A free-floating sponge media (BioCube) process. using a 24 L lab scale reactor, was operated to study the nitrification profiles and microbial community. The COD removal efficiencies were maintained. at an average of 95%,. with the mixed liquor suspended solids (MLSS) inside the BioCube sponge media maintained at 12,688 mg/L. The nitrification removal efficiencies were between 92%, and 100%. with an average value of 99%. From the results of microelectrode measurement, the ammonium ion concentration was found to rapidly decrease from the surface of the BioCube sponge media to a depth of 2 mm due to chemical reactions carried out by ammonia oxidizing bacteria (AOB) species. Multi-fluorescence in situ hybridization (FISH) has been used to investigate the spatial distributions of various microbial activities within reactors. Microbial communities were targeted using different oligonucleotide probes specific to AOB and nitrite oxidizing bacteria (NOB). There were a large number of AOB populations. but these were not distributed in the biofilm compared to the NOB populations. (C) 2007 Elsevier Ltd. All rights reserved.

Adsorption on activated carbon combined with ozonation for the removal of contaminants of emerging concern in drinking water

Beatrice Cantoni, Jessica Ianes, Beatrice Bertolo, Selena Ziccardi, Francesco Maffini, Manuela Antonelli

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.
