Director, Postgraduate Environment Education (Environmental Engineering), leading the development and delivery of taught postgraduate programmes, short courses and training in the subject area.
Also, along with Professor David Blackwood, I am a Co-Director of the Urban Water Technology Centre.
My research explores the characteristics of the complex microbial community associated with the control of environmental pollutants. The aim, essentially, is to develop and improve the technology for treating (and extracting useful products such as organic fertiliser, biogas and freshwater from) industrial and municipal wastes and wastewaters. My research in anaerobic digestion processes encourages regular consultations by public and private sector organisations trying to find solutions to organic waste issues. My current research areas include treatment of industrial and hospital wastewaters, small scale and decentralised wastewater treatment systems (e.g. package plants and constructed wetland systems), surface water quality management, remediation of oil contaminated land, landfill decay modelling and restoration of landfill sites, and waste and sanitation in developing countries.
• Undergraduate courses (Civil Engineering and Environmental Management)
Fluid mechanics and hydraulics, water and wastewater engineering, sewerage design, water supply and treatment, wastewater treatment, solid waste treatment and management, air pollution control.
• Postgraduate and Continuous Professional Development (CPD) programmes
Wastewater treatment, sewage sludge management, solid waste management, landfill technology, contaminated land remediation, water quality management, sanitation and waste management in developing countries. These programmes have strong industrial links and the MSc course is accredited by the Chartered Institution of Water and Environmental Management (CIWEM), the pre-eminent professional institution of the sector.
My research interest lies in the area of environmental technology, specialising in engineering application of biological, physical and chemical processes for the control and abatement of environmental pollutants, and in the production of bio-energy. My research aims at developing new (and improve existing) technologies for harnessing beneficial products from waste materials (e.g. organic fertiliser and bio-energy production organic residues) and for solving common environmental problems i.e., treatment of sewage, municipal and industrial waste, water treatment.
My special focus is on the identification, characterisation, manipulation and modelling of microbial interactions associated with the biodegradation of carbonaceous and nitrogenous compounds, leading to the optimisation and/or development of pollution abatement technologies.
Specific applications of my research address the following themes:
- Domestic and industrial wastewater treatment
- Decentralised wastewater treatment systems, including constructed wetlands
- Biological nutrient removal from wastewaters
- Sludge anaerobic digestion and disposal
- Anaerobic digestion (biogas production) of biodegradable organic residues and sludges
- Organic fertiliser production from biodegradable organic residues and sludges
- Solid waste management
- Landfill technology and decay modelling
Current PhD and Postdoctoral research projects:
- Anaerobic digestion and co-digestion of agricultural residues
- Modelling of anaerobic digestion processes
- Anaerobic digestion in high saline conditions
- Bioremediation of petroleum hydrocarbon contaminated soils and surface waters
- Development of cleaning technologies for the management of organic residuals from the distillery industry
- Treatment of hospital and pharmaceutical wastewaters
- Application of anaerobic digestion for sustainable household waste management in low income countries
- Low energy domestic wastewater treatment for effluent re-use
- Development of methodologies for the assessment and control of groundwater pollution in low income countries
- Biological characterisation of constructed wetland used for municipal wastewater treatment
