6. Sediment remediation using activated carbon: amending knowledge gaps
Abstract : Many coastal sediments have accumulated large quantities of contaminants from past anthropogenic activities and now act as a secondary emission source of legacy pollutants to coastal ecosystems. New sediment remediation strategies are needed to address widespread sediment pollution. READ MORE

7. Modeling adsorption of organic compounds on activated carbon : a multivariate approach
Abstract : Activated carbon is an adsorbent that is commonly used for removing organic contaminants from air due to its abundant pores and large internal surface area. This thesis is concerned with the static adsorption capacity and adsorption kinetics for single and binary organic compounds on different types of activated carbon. READ MORE

8. Towards application of activated carbon treatment for pharmaceutical removal in municipal wastewater
Abstract : Many pharmaceuticals are found in municipal wastewater effluents due to their persistence in the human body as well as in conventional wastewater treatment processes. This discharge to the environment can lead to adverse effects in aquatic species, such as feminization of male fish. READ MORE

9. From hydrothermal carbonization to blue hydrochars and activated carbons : Adsorption of volatile organic compounds and heavy metals
Abstract : Hydrothermal carbonization of carbohydrate and biomass is a straightforward method for preparing hydrochars at low temperature. Hydrochars are more carbonized than their precursors. Hydrochars themselves are carbon precursors for preparing activated carbons. Activated carbons are porous materials that can be used for water and air purification. READ MORE

10. Optimization methods for sedimentation and denitrification in activated sludge
Abstract : Denitrification on readily biodegradable carbon compounds and separation of biological sludge from effluent water are examples of critical sub-processes for nitrogen removal in activated sludge. The aim of this thesis was to find operational strategies and newmethods to optimize these processes. READ MORE
