   Keywords : wastewater heat recovery; green buildings; sustainable urban development; interface misalignment; critical interface; system analysis; niche; regime; värmeåtervinning av spillvatten; byggnader; energieffektivisering; hållbar stadsutveckling; systemanalys;

   Abstract : This thesis presents a system and actor level analysis of wastewater heat recovery in buildings, using two case studies in Stockholm, Sweden. The choice of these case studies was to cover the installation of WWHR in both commercial and residential buildings. READ MORE

3. 22. Are organohalogen compounds in backwash water from swimming pool facilities treatable? : An experimental investigation of removal capacities by different filter materials

   University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

   Author : Emma-Helena Ericsson; [2020]
   Keywords : AOX; EOX; wastewater treatment plant; column test; granular activated carbon; natural zeolites; Polonite r ; Zugol;

   Abstract : Organohalogen compounds are formed in swimming pool waters when natural organic matter, such as hair, urine or sweat etc., react with the used disinfectant (usually chlorine). Many of the organohalogen compounds are persistent and hazardous for human health and aquatic ecosystems. READ MORE

4. 23. “But I have always had the greenest lawn in my neighbourhood” – When what is taken for granted becomes rare : A qualitative study of how municipalities communicate sustainable use of drinking water
