  1. 31. Waste Heat Driven Membrane Distillation for Industrial Wastewater Treatment

    Författare :Imtisal-e- Noor; Andrew R. Martin; Olli Dahl; Mikel Duke; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Membrane Distillation; Experimental investigations; Techno-economic; Wastewater; Flue gas condensate; Waste heat; District heating; Nano-electronics; Cogeneration; Sustainable development; Energy Technology; Energiteknik; Chemical Engineering; Kemiteknik;

    Sammanfattning : The European Union has placed a high priority on reaching the goals described in the 2030 Agenda for Sustainable Development. This aim has provided added momentum to member-state environmental regulatory authorities to further tighten the discharge limits of industrial wastewater. LÄS MER

  3. 32. Pharmaceutical compounds; a new challenge for wastewater treatment plants

    Författare :Maja Dlugolecka; Elzbieta Plaza; Bengt Hultman; Nicklas Paxéus; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; activated sludge; biodegradation; granular activated carbon GAC ; membrane bioreactor MBR ; pharmaceutical compounds; wastewater; Water engineering; Vattenteknik;

    Sammanfattning : Analytical analyses conducted at the Himmerfjärden WWTP (285.000 PE connected) identified 70 pharmaceutical compounds belonging to different therapeutic classes. Such organic micropollutants at low detected concentration range of µg - ng l-1 did not affect the treatment processes at WWTP. LÄS MER

  4. 33. A passage to wastewater nutrient recovery units : Microalgal-Bacterial bioreactors

    Författare :Anbarasan Anbalagan; Jesus Zambrano; Sebastian Schwede; Carl-Fredrik Lindberg; Emma Nehrenheim; Francisco Gabriel Acién Fernández; Mälardalens högskola; []
