    Abstract : This thesis studied the viability of recycling filter substrates as soil amendments after being used in on-site systems for phosphorus (P) removal from wastewater. Focus was put on the materials Filtra P and Polonite, which are commercial products used in compact filters in Sweden. READ MORE

  2. 2. Assessing sustainable approaches to sanitation planning and implementation in West Africa

    University dissertation from Stockholm : KTH

    Author : Jennifer R. McConville; KTH.; [2008]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TECHNOLOGY Civil engineering and architecture; TEKNIKVETENSKAP Samhällsbyggnadsteknik och arkitektur; Decision-Making; Implementation; Planning; Sanitation; Sustainable;

    Abstract : The challenge of achieving global sanitation targets is that it requires application of both technology that is appropriate and a supporting organizational structure. The interactions between the two begin during the planning/decision-making process and continue throughout the system lifetime. READ MORE

  3. 3. Bed filters for phosphorus removal in on-site wastewater treatment Removal mechanisms and sustainability

    University dissertation from Stockholm : KTH Royal Institute of Technology (KTH)

    Author : David Eveborn; KTH.; [2010]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; On-site wastewater treatment; Eutrophication; Environmental impact assessment; Phosphorus removal mechanisms; Soil infiltration; Reactive bed filters; TECHNOLOGY Other technology Environmental engineering; TEKNIKVETENSKAP Övriga teknikvetenskaper Miljöteknik; TECHNOLOGY Civil engineering and architecture Water engineering; TEKNIKVETENSKAP Samhällsbyggnadsteknik och arkitektur Vattenteknik; FORESTRY; AGRICULTURAL SCIENCES and LANDSCAPE PLANNING Soil science Soil chemistry; SKOGS- och JORDBRUKSVETENSKAP samt LANDSKAPSPLANERING Markvetenskap Markkemi;

    Abstract : For many surface waters, phosphorus (P) leaching is a serious problem that should be minimized to prevent eutrophication. In Sweden there is a demand for physical and technical development of high-performance P removal techniques to reduce phosphorus leaching from on-site wastewater treatment systems to the Baltic Sea.

  4. 4. Groundwater-Seawater Interactions Seawater Intrusion, Submarine Groundwater Discharge and Temporal Variability and Randomness Effects

    University dissertation from Stockholm : KTH

    Author : Carmen Prieto; KTH.; [2005]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hydraulic engineering; Seawater intrusion; submarine groundwater discharge; coastal groundwater management; coastal zone management; temporal variability; temporal randomness; Vattenteknik; TECHNOLOGY Civil engineering and architecture Water engineering; TEKNIKVETENSKAP Samhällsbyggnadsteknik och arkitektur Vattenteknik;

    Abstract : Fresh groundwater quality and availability in coastal areas is affected by seawater intrusion into coastal aquifers, and coastal water quality and ecosystem status may be significantly affected by groundwater pollutants that are transported into coastal waters by submarine groundwater dis-charge (SGD). This thesis uses an overall regional perspective for investigating: i) seawater intru-sion and its possible control in sustainable coastal groundwater management; ii) SGD and its relevant quantification as one interacting part among the diverse main regional pathways of freshwater and tracer/pollutant inputs from land to sea; and iii) the integrated system functioning of both i) and ii) as main components of the same coastal groundwater system.
