  1. 21. Modeling Flow and Solute Transport in Packed Beds : Applications in On-site Wastewater Treatment Systems

    Författare :Amir Jourak; Krishna M. Pillai; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Strömningslära; Fluid Mechanics;

    Sammanfattning : The use of separate phosphorus (P) filter units containing replaceable filter materials with a high P binding capacity have been suggested as an appropriate passive method to treat the P from pre-treated domestic wastewater in on-site facilities. A large number of materials have been identified and suggested as being potentially suitable for such filters. LÄS MER

    Sammanfattning : Infrastructure for the provision of drinking water and the treatment of wastewater and stormwater, is essential for an urban society. In this project methods are developed which measure and assess the sustainability of urban water systems. LÄS MER

  5. 24. Enhancing anaerobic digestion in urban wastewater management

    Författare :Hamse Kjerstadius; Avdelningen för kemiteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : The thesis investigates how anaerobic digestion could be utilized to improve wastewater management,specifically in regards to future expected regulation on sludge management in Sweden.Two possible paths of applying anaerobic digestion are investigated. LÄS MER

  7. 25. Benchmark Simulation Model for Integrated Urban Wastewater Systems : Model Development and Control Strategy Evaluation

    Författare :Ramesh Saagi; Industriell elektroteknik och automation; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Benchmark Simulation Model; Integrated control strategies; Integrated modelling; River water quality;

    Sammanfattning : The integrated urban wastewater system (UWS) consists of different sections that are interconnected. These include: i) catchment; ii) sewer network; iii) wastewater treatment plant (WWTP); and finally, iv) receiving water system. Traditionally, these sections are operated and evaluated individually.
