  1. 11. Use and Development of Diffusive Samplers to Analyse the Fate of Polycyclic Aromatic Compounds, Polychlorinated Biphenyls and Pharmaceuticals in Wastewater Treatment Processes

    Författare :Lijana Augulyte; Patrik L. Andersson; Anna Ledin; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; bioavailable; biologically activated carbon; PRCs; sampling rate; SPMD; sorption; wastewater treatment; diffusive passive samplers; human pharmaceuticals; municipal sewage treatment plant; organic micropollutants; polycyclic aromatic compounds; PAHs; PCBs; POCIS; Environmental chemistry; Miljökemi;

    Sammanfattning : The efficiency of wastewater treatment systems is commonly measured by the reductions of parameters such as biological oxygen demand (BOD), chemical oxygen demand (COD) and total suspended solids (TSS) and/or reductions in levels of selected macro compounds (e.g. long-chained hydrocarbons and inorganic compounds).

    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biochar; Fortified filter; Gas concrete; Phosphorus removal; Reactive filter media; Wastewater treatment; Land and Water Resources Engineering; Mark- och vattenteknik;

    Sammanfattning : Concerns about potential risks posed by discharge from small-scale wastewater treatment (SWT) systems to receiving water bodies have prompted robust enforcement of national discharge quality standards in rural areas of most developed countries. Consequently, communities in such places are in need of effective technologies with which to achieve compliance. LÄS MER

  4. 13. Pharmaceuticals – improved removal from municipal wastewater and their occurrence in the Baltic Sea

    Författare :Berndt Björlenius; Gen Larsson; Antonius J. A. van Maris; Hallvard Ødegaard; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Advanced wastewater treatment; WWTP; pilot plant; pharmaceutical residues; removal of pharmaceuticals; activated carbon; ozonation; nanofiltration; biomarker; Baltic Sea; Bioteknologi; Biotechnology;

    Sammanfattning : Pharmaceutical residues are found in the environment due to extensive use in human and veterinary medicine. The active pharmaceutical ingredients (APIs) have a potential impact in non-target organisms. Municipal wastewater treatment plants (WWTPs) are not designed to remove APIs. LÄS MER

  5. 14. Treatment of Wastewater Generated by Wood-based Dry Industries : Advances Oxidation Processes & Electrocoagulation

    Författare :Henrik Hansson; William Hogland; Marcia Marques; Ollie Dahl; Linnéuniversitetet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Advanced oxidation processes; Electrocoagulation; Fenton; Industrial storm-water; Ozone; Respirometry assays; Wastewater; Wood floor industry.; Environmental Chemistry; Miljökemi;

    Sammanfattning : Wood is a material with an enormous number of applications. For decades, the development of wastewater treatment technologies tailored for the wood sector has focused on those industries that have water as an integral part of the industrial production, such as paper and pulp.

  7. 15. Wastewater generated by the wooden floor industry : Treatability investigation applying individual and coupled technologies

    Författare :Sawanya Laohaprapanon; William Hogland; Marcia Marques; Eduardo C. Pires; Linnéuniversitetet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Wooden floor industry; activated carbon sorption filtration; anaerobic biological treatment; chemical precipitation; electrocoagulation; ecotoxicity; Miljövetenskap; Environmental Science; Environmental technology; Miljöteknik;

    Sammanfattning : During the last half-century a growing concern has taken place in the world regarding water shortage and public health associated to water pollution. Safe discharges of industrial effluents and water reuse within the industry have been encouraged and several initiatives have promoted the development of wastewater treatment technologies with the main focus on industrial sectors that generate large volumes of wastewater.
