  2. 1. 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

  4. 2. Municipal wastewater treatment by microsieving, microfiltration and forward osmosis : Concepts and potentials

    Author : TOBIAS HEY; Avdelningen för kemiteknik; []
    Keywords : Direct membrane filtration; electricity; energy; forward osmosis; microfiltration; microsieving; municipal wastewater treatment; treatment concept; Direct membrane filtration; Electricity; Energy; Forward osmosis; Microfiltration; Microsieving; Municipal wastewater treatment; Treatment concept;

    Abstract : Conventional wastewater treatment plants are designed for treating manmade wastewater (e.g., from households and industries) and to protect the environment (e.g. READ MORE

  5. 3. Indigenous microalgae-activated sludge cultivation system for wastewater treatment

    Author : Anbarasan Anbalagan; Emma Nehrenheim; Carl-Fredrik Lindberg; Sebastian Schwede; Raquel Labrero; Mälardalens högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy- and Environmental Engineering; energi- och miljöteknik;

    Abstract : The municipal wastewater is mainly composed of water containing anthropogenic wastes that are rich in nutrients such as carbon, nitrogen and phosphorous. The cost for biological treatment of wastewater is increasing globally due to the population growth in urban cities. READ MORE

  6. 4. Microbiological analysis of municipal wastewater treating photobioreactors

    Author : Ivo Krustok; Monica Odlare; Emma Nehrenheim; Jaak Truu; Raul Muñoz; Mälardalens högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; photobioreactors; wastewater treatment; microalgae; microbiology; Energy- and Environmental Engineering; energi- och miljöteknik;

    Abstract : Microalgae reactors, commonly known as photobioreactors, have become increasingly popular as an alternative for wastewater treatment. These systems reduce pollutants and remove nutrients such as nitrogen and phosphorous compounds from wastewater utilizing microalgae and bacteria. READ MORE

  7. 5. New Dimensions of Moving Bed Biofilm Carriers : Influence of biofilm thickness and control possibilities

    Author : MARIA PICULELL; Avdelningen för kemiteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; biofilm control; biofilm thickness; biological wastewater treatment; carrier; moving bed biofilm reactor; nitrification; nitritation; organic removal; process optimization; scaling; suspended growth;

    Abstract : The moving bed biofilm reactor (MBBR) is a biological wastewater treatment process in which microorganisms grow as biofilms on suspended carriers. Conventionally, MBBRs are mainly designed and optimized based on the carrier surface area, neglecting the dynamic relationship between carrier design, reactor operation and biofilm characteristics, such as biofilm thickness and the composition of the microbial community.
