The domain of specialisation is pollutant removal from wastewater with biological processes and microbial characterisation of these systems. Presently, the research is focused on allying microbiology to process engineering to achieve a deeper knowledge on the microbial populations and their role on particular wastewater treatment processes, namely on the following projects:
- Membrane biological reactors for wastewater treatment
- Denitrifying phosphorus removal process
- Xenobiotic removal from domestic wastewater
- Characterization of mercury removing microbial populations enriched for drinking and waste water treatment.
