  2. 11. Application of aerobic granular sludge for municipal wastewater treatment - Process performance and microbial community dynamics under fluctuating conditions

    Author : Jennifer Ekholm; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; energy usage; aerobic granular sludge; sequencing batch reactors; granulation; municipal wastewater treatment; nutrient removal; start-up; microbial community dynamics; full-scale operation; low temperature; activated sludge;

    Abstract : Pressures of growing cities, competition for use of urban areas and higher influent loads, are pushing for innovative technologies for wastewater treatment with low demands for land footprint and costs. Furthermore, wastewater treatment is needed to move towards a circular economy by harvest of valuable resources such as nutrients and energy. READ MORE

  4. 12. Assessment of stormwater and snowmelt quality based on water management priorities and the consequent water quality parameters

    Author : Helen Galfi; Maria Viklander; Jiri Marsalek; Helene Österlund; Jon M. Hathaway; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Stormwater quality; indicator bacteria; water quality assessment; VA-teknik; Urban Water Engineering; Centre - Centre for Stormwater Management DRIZZLE ; Centrumbildning - Centrum för dagvattenhantering DRIZZLE ;

    Abstract : Stormwater and snowmelt pollution contributes to degradation of quality of the receiving waters. For assessing such impacts, it is effective to focus on specific causes of degradation, as done in this study of the quality of stormwater and snowmelt discharges into the receiving waters serving for supply of raw drinking water and water-based recreation.

  5. 13. Development of Decision Support Tools for Urban Water Supply Management in Uganda

    Author : Frank Kizito; Roger Thunvik; Patrick Ogao; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Decision support systems; Participatory decision-making; Geovisualization; Non-revenue water; Geostatistics; Action research; Water engineering; Vattenteknik;

    Abstract : In this study, five real-life problem situations were used to explore the challenges of developing and implementing decision support tools for management of an urban water utility in Uganda. The study sought to explore how the degree of adoption of formal decision support tools in practice, generally perceived to be low, could be improved. READ MORE

  6. 14. Forest water governance : challenges in cross-sectoral and multi-level collaboration
