Aerobic granular sludge: Scaling up a new technology

Most conventional wastewater treatment plants need a large surface area for the treatment of their sewage. This is due to the open structure of the biomass used to convert the polluting components in wastewater. Because of the flocculated growth, sludge concentrations in reaction tanks are low and settling times need to be long in order to keep...

Influence of volatile fatty acids on aerobic granular sludge performance and considerations for pre-fermentation

Pre-fermentation of influent has been proposed as a method to improve phosphorus removal capacity, granulation, and simultaneous nitrification denitrification for aerobic granular sludge plants. This thesis sought to determine the influence of increasing VFA concentrations on performance of aerobic granular sludge plants and key considerations...
