1. Removal of Organic Micropollutants from Wastewater in Biofilm Systems
Abstract : The presence of organic hazardous substances in the aquatic environment, such as pharmaceutically active compounds and personal care products, has become a worldwide issue of increasing environmental concern. Present at concentration of nano- to milligram per liter, they are defined as organic micropollutants (OMPs). READ MORE

2. Excess heat utilisation in oil refineries - CCS and algae-based biofuels
Abstract : The main objective of this thesis is to investigate two different concepts for CO2 mitigation, from a system perspective, in relation to the oil refining industry: CO2 capture and storage; and algae-based biofuels. For all these processes, process integration with an oil refinery is assumed. READ MORE

5. Influence of electrode material and stochastic factors on the performance and microbial community assembly in microbial electrochemical systems
Abstract : Microbial electrolysis cells (MECs) are systems with microbial communities in the form of biofilms on electrode surfaces. The electrogenic bacteria in the anode biofilm act as catalysts for the oxidization of organic compounds, leading to release of electrons, generation of electrical current, and production of hydrogen and methane at the cathode.
