Project Number # 4522-16

Optimisation of granular sludge for energy efficient wastewater treatment and reuse

Project Leader:  Ben Thwaites

 

Traditional activated sludge (AS) is used widely around the world for biological nitrogen removal from wastewater treatment plants (WWTP). Aerobic granular sludge (AGS) is an emerging technology which has the potential to replace the traditional microbial floc with dense microbial granules allowing for greater volumes of wastewater to be treated. The process of implementation at existing WWTP has not previously been investigated for impacts on water recycling, energy use or greenhouse gas emissions.
