Phage treatment of filamentous bacteria in activated sludge
The activated sludge process is one of the most commonly used wastewater treatment processes, which consists of a biochemical stage (aeration basin) and physical separation (secondary clarifier). The successful operation ...
Simulating the behaviour of skim-milk during ultrafiltration
Many commercial dairy products such as cheese and concentrated milk proteins are produced via ultrafiltration of skim-milk. During skim-milk ultrafiltration, a permeate stream comprising lactose, water and other minerals ...
Synthesis of hierarchically macro/mesoporous silica beads
Hierarchically porous materials have potential applications in energy storage and conversion, catalysis, separation and bioengineering. The hierarchically porous structure provides the material with both large quantities ...
Extrusion 3D-printing of functional polymers
Since its early introduction in the 1980s, 3D-printing has attracted considerable attention owing to its revolutionary ability to manufacture hierarchically complex structures in a simple and customable manner. With the ...
Application of graphics processing units to the Lattice Monte Carlo Method for predicting and modelling thermal conduction
The Lattice Monte Carlo (LMC) method has been successfully applied to a range of scenarios involving pure thermal conduction/diffusion. Extensive investigations by Murch, Belova and Fiedler have exemplified the utility of ...
A fundamental study of concentration polarisation and fouling in skim milk ultrafiltration
Skim milk ultrafiltration (UF) is an important dairy process operation in which milk proteins are preferentially concentrated for downstream manufacturing of cheese and milk protein concentrates (MPC), and also for protein ...
Peptide-based materials and the assembly of peptide-based nanostructures
Amyloid fibrils are highly ordered protein aggregates associated with the disease that has been identified in deposits, including different organs and tissues of mammals, where they are known as corpora amylacea. κ-casein, ...
A fundamental study of membrane fouling using a novel microfluidic filtration system
Membrane filtration has been widely employed in dairy manufacturing, wastewater treatment, and beverage clarification. However, the issue of membrane fouling significantly reduces the filtration performance by increasing ...
Bioenergy with carbon capture and storage; sustainability, challenges, and potential
Bioenergy with carbon capture and storage (BECCS), as a negative emission technology, has been assigned a key role for achieving ambitious mitigation targets in several climate models. BECCS is a multifaceted complex ...
Quantification of wastewater dewaterability for understanding sludge dewatering and fouling during membrane bioreactor operation
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 ...
