Growing demands for potable water have strained water resources and increased interest in wastewater reclamation for potable reuse. This interest has brought increased attention to endocrine-disrupting chemicals (EDCs) as emerging water contaminants. The effect of EDCs, and in particular natural steroid hormones, on humans is of heightened interest in the study of wastewater reuse in advanced l...

Membrane Bioreactors (MBRs) have attracted a significant attention of scientists and engineers in the past two decades. Improvement of membrane technologies coupled with experiences gained from application of membranes in different industrial processes have opened a gamut of opportunities in industrial wastewater treatment. The solidliquid separation that is conventionally carried out in gravit...

Reclaimed wastewater has become a potential water resource for many dry areas. Its recovery should be regarded as an additional stage in the water cycle providing a new water resource and preserving other high quality sources for more demanding applications. However, in this new scenario, a special attention should be paid to its physicochemical and microbiological quality to avoid damage to pu...

For decades, the city of Windhoek in Namibia succeeded in stretching their limited potable water resources through strict water management, latterly including wastewater reclamation and direct potable reuse. An integrated approach was followed and proper policies were put in place. This was followed up with appropriate legislation, education, policing and technical and financial measures with t...

Developing technical alternatives to increase the volume of remediated waters is a promising way alleviate pressure on natural water basins. However, extra energy consumed in Wastewater Treatment Plants (WWTPs), mainly powered by fossil fuels, hampers this strategy. This work focuses promoting efficient upgrading treated recovering within treatment process. The approach consists recovery and in...

The performance of the Sha-he wastewater reclamation plant was evaluated in this study. To remove residual nitrogen after Anaerobic-Anoxic-Oxic (A2O) treatment, three multistage Anoxic-Oxic (A/O) were added to investigate the nitrogen removal efficiency and its mechanism. In addition, the constituents and evolution of dissolved organic matter (DOM) during wastewater reclamation was also investi...

Ultrafiltration (UF) has become one of the dominant treatment processes for wastewater reclamation in China. Modeling is an effective instrument to understand and optimize UF systems. To this end, a previously developed UF model for organics removal was applied to the UF process in a typical, full-scale wastewater reclamation plant (WRP) in China. However, the sparse and incomplete field monito...

Decentralized water reclamation is emerging as a new paradigm that pairs local wastewater resources with local users; however, one of the challenges that must be addressed to advance its implementation is the low energy efficiency associated with small treatment plants and the lack of available small-scale energy recovery technologies. Gasification is a technology that could be used to convert ...
