Abstract
This thesis investigated the dewatering properties of wastewater treatment sludges, and biofouling layers in membrane bioreactors. An experimental and data analysis methodology was developed that unified existing procedures for lab-scale filtration, centrifugation and gravity settling tests. This unified dewaterability characterisation methodology was used to quantitatively compare fifteen wastewater sludge samples. The comparison highlighted a correlation between lower volatile suspended solids and improved filterability. Further modelling of the extreme compressibility of biofouling layers has provided insights into optimisation of water recycling.
