Unraveling activated sludge bioflocculation - Belgium
KU Leuven (company)
Posted on : 19 July 2017
- The cost efficiency and sustainability of biological wastewater treatment systems highly depends on the bioflocculation ability of the so-called activated sludge bacteria which should ensure a proper sludge-water separation.
- One of the most important building blocks of activated sludge flocs are the bacterial microcolonies which dictate the overall strength of the floc.
- This strength cannot be fully explained by the commonly accepted electrostatic and hydrophobic forces. Hence, this research will investigate whether lectins play a role in strong microcolony formation.
- Lectins are non-enzymatic proteins that can bind specific carbohydrates and typically accumulate on the outer cellular membrane.
- They have been reported to play an important role in, e.g., yeast bioflocculation and in the coaggregation of bacteria in dental plaque and aquatic biofilms but are thus far not thoroughly investigated in the context of activated sludge bioflocculation.
- The here envisaged PhD project encompasses a strong experimental part in which a combination of wet chemical, molecular genetic, proteomic and (fluorescence) microscopy techniques are exploited to unravel the functionality and dynamics of lectins.
- You are passionate about biological wastewater treatment systems
- You are skilled in basic experimental work involving biological systems
- Your possible skills regarding molecular genetic techniques (such as FISH) are a plus
- You are proficient in written and spoken English
- You are a good communicator
- You are a team player
- You have did a ctical interests
- Full-time 2-year contract, with the possibility of an extension
- Enrollment at one of the top universities in Europe
- Exciting and dynamic research environment
- Competitive salary
