  1. 1. Air diffusion and solid contaminant behaviour in room ventilation : a CFD based integrated approach

    Författare :Gery Einberg; Sture Holmberg; hazim Awbi; KTH; []
    Nyckelord :Technology; CFD modelling; airflow rate; ventilation efficiency; diffusers; solid contaminants; IAQ; TEKNIKVETENSKAP; TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : One of the most fundamental human needs is fresh air. It has been estimated that people spend comparatively much time in indoor premises. That creates an elevated need for high-quality ventilation systems in buildings. The ventilation airflow rate is recognised as the main parameter for measuring the indoor air quality. LÄS MER

  3. 2. Targeted and untargeted analysis of organic contaminants from on-site sewage treatment facilities : Removal, fate and environmental impact

    Författare :Kristin Blum; Peter Haglund; Patrik Andersson; Pim Leonards; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; decentralized sewage treatment; wastewater; surface water; environmental fate; bioavailability; removal efficiency; mass fluxes; biochar; environment; GC×GC-MS; LC-IM-MS; mass spectrometry; contaminants; pollutants; prioritization; non-target analysis; screening; analytisk kemi; Analytical Chemistry;

    Sammanfattning : On-site sewage treatment facilities (OSSFs) are widely used all over the world to treat wastewater when large-scale sewage treatment plants (STPs) are not economically feasible. Although there is great awareness that the release of untreated wastewater into the environment can lead to water-related diseases and eutrophication, little is known about organic contaminants and their removal by OSSFs, environmental load and fate.

  4. 3. Towards sustainable solid waste management in Jordan

    Författare :Mohammad Aljaradin; Avdelningen för Teknisk vattenresurslära; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Solid Waste Management; Public Participation; Recycling; Landfilling; Jordan;

    Sammanfattning : Jordan is a country with a growing population that is undergoing rapid modernization. The increased volume of solid waste and associated logistical difficulties, the steady growth in the cost of waste management and the risk to human health are sources of concern. LÄS MER

  5. 4. Characterisation of residues : Release of contaminants from slags and ashes

    Författare :Ann-Marie Fällman; Rob N.J. Comans; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Residues from industrial processes as well as from energy production utilities have in many cases properties similar to geological materials. They can be used as filling and construction materials if the net environmental impact and the technical properties are acceptable. LÄS MER

  7. 5. Removal of endocrine-disrupting compounds from wastewater using molecular imprinting

    Författare :Mathieu Le Noir; Bioteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; molecular imprinting; Endocrine-disrupting compounds; wastewater; macroporous gel; trace contaminants;

    Sammanfattning : Endocrine-disrupting compounds (EDCs) such as hormones and certain pharmaceuticals (i.e. birth control pills, oestrogen replacement products and other steroids) can interfere with the regulatory systems of humans and wildlife. Many of these compounds are excreted by humans and released with sewage. LÄS MER
