Biography

Dr Wu is an Associate Professor (Reader) in Bioengineering. Her research interests are in the areas of bone, ocular tissue, numerical modelling of natural and synthetic polymers, biomaterials for prostheses bearing surfaces, and functional tissue engineering.

She obtained her MSc in Computer Science (Parallel Computing) from Oxford University Computing Laboratory and a DPhil from Department of Engineering Science at Oxford University, where she was a Career Development Fellow before joining the University of Durham.

Since joining Durham, she has held and is currently holding research fundings as Principal investigator in Biomaterials, Modelling, Tissue engineering and Biotribology for a number of recent projects.

She is teaching/has taught the following courses: Bioengineering, Materials, Polymers, Metals and Alloys, Fluid Mechanics, Engineering Design, Dynamic System Modelling and Engineering drawing.

Bio-Energy, Energy Efficiency and Water PhD Projects available

Project 1 Improving Energy Efficiency in a Modern Water Factory

The combination of a water reclamation plant (such as NEW Water plants) with seawater desalination are being considered in many large developing mega cities around the world. Away from coasts water recycle will become even more important. We have developed a novel hybrid process that needs to be evaluated alongside other process schemes for various water usage scenarios. The process design algorithms available include our recently published methodology for the sizing of forward osmosis plants. This project has international and industrial technical support.

Project 2 Sustainable energy: Potential in Osmotic Power

Just as the separation of salty water into fresh water and a brine requires energy so the mixing of a brine and fresh water can (if it is done in a controlled manner) produce energy. Originally proposed in a Science paper around 50 years ago, there has been much research into osmotic power (variously called pressure retarded osmosis or generically “Blue Energy”). Now that membranes have been tailored for this application and greatly improved the limits to performance are no longer governed by the membrane properties alone. The project will develop a performance envelope based upon various combinations of membrane properties and system hydrodynamics.

 Project 3 Improving Energy Efficiency of Aerobic Digestion

Successful operation of Aerobic Digestion in cold weather is challenging. We have discussed a novel approach with the water industry and the research question is: can our approach boost the growth rate of the microbial biomass? 

Project 4 Solar Driven, Gravity Driven and Other ‘Low Energy’ Potable Water Treatment Processes

Drinking water is scarce in many parts of the world were solar energy is plentiful. The project boundary is such as to exclude those processes with a relatively high demand of electrical power. Many processes have been labelled as “emerging processes” for the last decade. After an initial survey three processes from different areas will be evaluate to determine if any have break through potential.

Project 5 Potable Water Treatment Using Direct Flow Membrane Modules: Design of Hollow Fibre Modules

Membranes are now a huge part of the water market, especially since the advent of the Direct Flow modules that uses far less energy than crossflow modules. These are hollow fibre modules with about 10 000 fibres per module. We have developed a model for side take-off that successful captures industrial practice. Other variants are being developed. Now as non-uniform distribution of fibres is intrinsic to the manufacturing process research on the effect of non-uniformity should now be included. We are progressing this work with industrial technical support.

Project 6 Potable Water Treatment Using Direct Flow Membrane Modules: Influence of Cleaning Chemicals Upon Fibre Integrity.

Successful operation of the Direct Flow format is dependent upon the inclusion of periodic backwashes including chemically enhanced backwashes. As the latter may be a few times per day the membranes are exposed regularly to oxidising chemicals. We have piloted a technique for performing accelerated tests and obtained excellent preliminary results. This project has industrial technical support.
