Learning Outcomes

Upon successful completion of this course the students will acquire new knowledge and specific skills on the following subjects:

  • Will gain knowledge on: Soil and groundwater bioremediation technologies, rehabilitation technologies of marine ecosystems from oil spills, phytoremediation systems and slurry bioreactors for soil treatment.
  • Will be able to understand: The conditions that require in situ or ex situ remediation techniques.
  • Will be able to use: Necessary tools for calculating the remediation time for contaminated sites.
  • Can recognize: The type of pollution, the ease of degradation by biological processes, as well as their risk.
  • Can analyse: Polluted areas with regard to existing pollutants and their alternative remediation processes.
  • Can evaluate: The effectiveness of bioremediation processes.
