  1. 1. Microsieving in municipal wastewater treatment : Chemically enhanced primary and tertiary treatment

    Author : Janne Väänänen; Avdelningen för kemiteknik; []
    Keywords : coagulation; wastewater treatment; flocculation; microsieving; control; primary treatment; tertiary treatment; coagulation; control; flocculation; microsieving; municipal wastewater treatment; primary treatment; tertiary treatment;

    Abstract : Municipal wastewater treatment plants are constantly forced to make improvements. The main objectives are to reduce energy consumption, to increase the treatment capacity and to improve the effluent water quality. Microsieves in combination with chemical pretreatment can potentially fulfil these objectives. READ MORE

  2. 2. Fault Detection in Wastewater Treatment : Process Supervision to Improve Wastewater Reuse

    Author : Heidi Lynn Ivan; Monica Odlare; Valentina Zaccaria; Jan Skvaril; Tiina Komulainen; Mälardalens universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wastewater treatment; Process supervision; Fault Detection; Energy- and Environmental Engineering; energi- och miljöteknik;

    Abstract : As wastewater treatment plants transition to water resource recovery facilities, the need for improved control and consequently supervision increases. Despite the large volume of research that has been performed on this topic, the use in industry is scarce. READ MORE

  3. 3. 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. 4. 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
