Performance of aerobic granular sludge in a sequencing batch bioreactor for slaughterhouse wastewater treatment

Untitled

“…Dairy wastes are pollutants that affect the environment when they are discarded without adequate treatment (Liu et al, 2015b). In the last decades, fatty effluents have been released to the environment without previous treatment (Kumari et al, 2017;Tarón-Dunoyer et al, 2017), which affects public health and environmental sustainability.…”

Petrochemical slop wastewater treatment by means of aerobic granular sludge: effect of granulation process on bio-adsorption and hydrocarbons removal

“…On the other hand, biological processes are environmental-friendly but, at the same time, they could not be effective in presence of recalcitrant and toxic pollutants as well as at high salinity operational conditions due to inhibition effects towards microbial cells [4][5][6][7]. Aerobic granular sludge (AGS) technology is a particular biofilm system where microorganisms are self-aggregated in granules [8] and it appears as one of the most promising biotechnologies able to treat industrial recalcitrant wastewater [2,9] both as synthetic [10][11][12][13], and real wastewater from various sectors (slaughter house, rubber industry, palm oil mill effluents, brewery, winery, dairy industry, landfill leachate) [14][15][16][17][18][19][20]. Recently, an emerging research topic relating the AGS technology is the peculiarity of granules to bio-adsorb the particulate fractions of industrial wastewater, thus increasing the contact time between microorganisms and substrates.…”

Researching New Ways to Reduce N2o Emission From a Granular Sludge Sequencing Batch Reactor Treating Domestic Wastewater Under Subtropical Climate Conditions

“…Sequencing batch reactors (SBR) with aerobic granular sludge (AGS) are presented as a promising option for the biological treatment of domestic and industrial effluents, due to the efficiency and robustness of this type of system (Di Bella and Torregrossa, 2013;Moreira et al, 2015;Pronk et al, 2015). With this technique, it is possible to obtain high removal rates of organic matter and nutrients in a single reactor, producing a final effluent with high quality (De Kreuk et al, 2005;Liu et al, 2015). However, the dynamics of nitrogen removal in this process, including nitrous oxide emission, are not completely understood; thus, further research is required.…”
