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. Change of toxicity during secondary treatment of industrial sludge containing nitroaromatics

   Author : Lillemor Gustavsson; Magnus Engwall; Anna Schnürer; Ulrika Welander; Mårten Jönsson; Bo Mattiasson; Göran Dave; Örebro universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Anaerobic; aerobic; AhR agonists; CALUX; constructed wetlands; Danio rerio; embryotoxicity; genotoxicity; nitroaromatics; sludge; Environmental engineering; Miljöteknik; Enviromental Science; Miljövetenskap;

   Abstract : Wastewater treatment plants in Sweden are facing a great challenge due to the prohibition of depositing organic waste which gained legal force in January 2005. Biological and commercial available alternatives to disposal are composting and anaerobic digestion. READ MORE

5. 3. Anammox-based systems for nitrogen removal from mainstream municipal wastewater

   Author : Andriy Malovanyy; Elzbieta Plaza; Adriano Joss; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wastewater; Nitrogen removal; Ion exchange; Deammonification; Anammox; Mainstream; Mark- och vattenteknik; Land and Water Resources Engineering;

   Abstract : Nitrogen removal from municipal wastewater with the application of deammonification process offers an operational cost reduction, especially if it is combined with a maximal use of organic content of wastewater for biogas production. In this thesis, two approaches for integration of the deammonification process into the municipal wastewater treatment scheme were studied. READ MORE

6. 4. Waste Heat Driven Membrane Distillation for Industrial Wastewater Treatment

   Author : Imtisal-e- Noor; Andrew R. Martin; Olli Dahl; Mikel Duke; KTH; []

   Abstract : 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. READ MORE

7. 5. Pharmaceutical compounds; a new challenge for wastewater treatment plants

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

   Abstract : 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. READ MORE
