The organic sludges arising from wastewater treatment processes are being investigated with regard to their safe and sustainable use for agriculture.
Studies are being conducted on the assessment and tracking of microbiological pathogen indicators in wastewater treatment processes and the resultant biosolids, and the factors which lead to their die-off. The efficacy of the utilisation of biosolids as soil amendments for crops in terms of nutrients and soil organic matter is under investigation. Studies are also being conducted on the hydrodynamics of biofouling, rheology and handling of sludges, particularly with regard to the mixing and thus efficient energy generation in anaerobic digesters.

Major project areas
- Evaluating microbial and chemical safety in sludge treatment in wastewater treatment systems and the beneficial utilisation of the resultant biosolids.
- Effect of ecosystem services on the removal of pathogens in applied reclaimed water and biosolids.
- Biogas production from municipal wastewater and industrial wastes: optimisation through pre-treatment and also rheological design to enhance digester mixing and sludge heating.
