  1. 21. Characteristics of Particulate Emissions from Low Temperature Combustion and Renewable Fuels : Aerosol Mass Spectrometry of Refractory Carbonaceous Particles

    Författare :Vilhelm Malmborg; NanoLund: Centre for Nanoscience; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Emissions; Soot; BC; BrC; ROS; SP-AMS; MiniCAST; Diesel Engine; HVO; RME; Cook Stove; Emissions; Soot; BC; BrC; SP-AMS; ROS; MiniCAST; Diesel Engine; HVO; RME; Cook Stove;

    Sammanfattning : Particulate air pollution is one of the major causes of premature death in the world, and combustion-derived soot emissions contribute strongly to the particulate pollution to which humans are exposed. Black carbon (BC) is one such emission and denotes soot with strong light absorption in the ultraviolet to infrared spectrum. LÄS MER

  3. 22. Accumulation and Composition of Gully Pot Sediments under Varying Anthropogenic Activities

    Författare :Haoyu Wei; Lian Lundy; Maria Viklander; David Butler; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Catch basin; Stormwater; Sediment; Urban runoff; Xenobiotics; Gully pot maintenance; Emerging pollutant; VA-teknik; Urban Water Engineering;

    Sammanfattning : Gully pots (GPs) are an integral urban drainage component, contributing to conveying runoff from urban surfaces and reducing the load of solids and associated contaminants entering downstream piped systems and receiving waters. Over time, the silting-up of GPs impairs their hydraulic performance, increasing the risk of GP blockage-induced flood events and reducing solids retention performance. LÄS MER

  4. 23. Solar-based physicochemical-biological processes for the treatment of toxic and recalcitrant effluents

    Författare :Tamer Essam; Bioteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Bioteknik; Biotechnology; combined process; biodegradaiton; phenolics; phenol; Advanced Oxidation Processes; Photodegradation; photolysis;

    Sammanfattning : Wastewater treatment is a worldwide necessity that is even more crucial to countries deprived from abundant fresh water sources or unable to afford advanced and costly processes. With this perspective, this thesis was conducted within an Egyptian-Swedish research collaboration that aimed to develop solar-based (as free renewable energy source available locally) process for hazardous wastewater treatment.
