NORMAN A University of Oklahoma-led interdisciplinary global study expands the understanding of activated sludge
microbiomes for next-generation wastewater treatment and reuse systems enhanced by microbiome engineering.
The Davyhulme Treatment Works opened in 1894 and has been at the forefront of Innovation ever since, not least with a breakthrough in the drive to improve the treatment process when, in 1914, two chemists, Ardern and Lockett, discovered the 'Activated Sludge
Process', soon after in use worldwide.
RLW's scope of work will focus on the structural concrete portion of the project, which includes the headworks, returned activated sludge
, ultraviolet disinfection, and electrical buildings, as well as the bioreactors, clarifiers, and solids holding tank.
The comparison of technologies for the removal of heavy metals and TOC was conducted by using activated sludge
and effluent from an operating municipal WWTP.
The most common process for the second operation is the activated sludge
Therefore, an activated sludge
process cannot achieve effective reduction of COD and an advanced treatment process must therefore be developed.
One substitution would be activated sludge
, yellowish-brown flocculants and particulates, which was confirmed to adsorb and accumulate PAEs from municipal wastewater [9, 15, 16], due to the composition of microbial communities characterized with porous structure and extracellular polymers resulting in large surface area, strong adsorption, and plentiful biological activities.
Environmental Engineering and Activated Sludge
Processes: Models, Methodologies, and Applications
Treatment of tannery effluent through the use of activated sludge
process has been reported by many researchers (Ahmed et al., 2014; Al-Hussieny et al., 2014; Deepika et al., 2014; Pal et al., 2014; Shyam et al., 2014; Ambreen et al., 2013; Mouna et al., 2013; Niaz et al., 2012; Durai et al., 2011).
The increasing volumes of wastewater produced and stricter regulations that are frequently put into practice cause a continuous increase of volumes of the waste activated sludge
generated from wastewater treatment plants making it vital to search for alternative methods that can improve the performance of the wastewater treatment plants to produce more treated water.
