  2. 1. Perspectives on Biofilms for the Removal of Organic Micropollutants in Wastewater

    Author : Ellen Edefell; Avdelningen för kemiteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wastewater treatment; wastewater; biofilm; ozonation; activated carbon; powdered activated carbon; granular activated carbon; biological degradation; Moving bed biofilm reactor;

    Abstract : The use of biofilms to improve the removal of organic micropollutants in waste¬water treatment plants (WWTPs) has been investigated. The work is divided into two parts. In the first part, the use of biofilms for the biological degradation of micro¬pollutants was investigated. READ MORE

  4. 2. Towards application of activated carbon treatment for pharmaceutical removal in municipal wastewater

    Author : Victor Kårelid; Gen Larsson; Gunno Renman; Ola Svahn; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; advanced wastewater treatment; granular activated carbon; powdered activated carbon; municipal wastewater treatment; pharmaceutical removal; Bioteknologi; Biotechnology;

    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

  5. 3. Sediment remediation using activated carbon: amending knowledge gaps

    Author : Robert A. Rämö; Jonas S. Gunnarsson; Agnes M. L. Karlson; Francisco J. A. Nascimento; Barbara Beckingham; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; sediment contamination; sediment remediation; sorbent amendment; activated carbon; benthic community; macroinvertebrates; Baltic Sea; Marine Ecotoxicology; marin ekotoxikologi;

    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

  6. 4. The influence of soil and contaminant properties on the efficiency of physical and chemical soil remediation methods

    Author : Sofia Jonsson; Mats Tysklind; Peter Haglund; Staffan Lundstedt; Tuula Tuhkanen; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Fenton’s reagent; ozone; solvent washing; granular activated carbon; GAC; Persistent organic compounds; Persistenta organiska föreningar; Cardiology; kardiologi;

    Abstract :  A vast number of sites that have been contaminated by industrial activities have been identified worldwide. Many such sites now pose serious risks to humans and the environment. Given the large number of contaminated sites there is a great need for efficient, cost-effective  remediation methods. READ MORE

  7. 5. Effects of Natural Organic Matter on Herbicide Adsorption to Activated Carbon

    Author : Åsa Edell; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; natural organic matter; herbicide; adsorption isotherm; preloading; activated carbon; competitive interaction;

    Abstract : The presence of pesticides in the aquatic environment represents a potential threat to water quality and human health. Increasingly stringent drinking water quality directives focus on the need for efficient pesticide removal processes. READ MORE
