  1. 1. Intermolecular interactions in hydrogen bonded 1:1 molecular complexes. A matrix isolation study

    Author : Anders Engdahl; Biokemi och Strukturbiologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; infrared laser irradiation; dimethyl ether; water dimer; hydrogen chloride; formamide; acetone; formic acid; ammonia; water; intermolecular; matrix isolation; FIR; FTIR; infrared; isomerisation; ab initio; Physical chemistry; Fysikalisk kemi;

    Abstract : A number of matrix isolated binary hydrogen bonded complexes with water as one of the components have been investigated with FTIR in the mid and far infrared regions. Water has been found to be the hydrogen bond donor in complexes with water, ammonia, dimethyl ether and acetone. READ MORE

  2. 2. Biogeochemical Processes in Denitrifying Woodchip Bioreactors and their Application in the Mining Industry

    Author : Albin Nordström; Roger Herbert; Fritjof Fagerlund; Gunno Renman; Uppsala universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; NATURVETENSKAP; TEKNIK OCH TEKNOLOGIER; NATURAL SCIENCES; ENGINEERING AND TECHNOLOGY; water treatment; mine drainage; nitrate; nitrous oxide; DNRA; fermentation; syntrophy; temperature; kväverening; gruvvatten; nitrat; lustgas; DNRA; fermentation; syntrofi; temperatur; Hydrology; Hydrologi;

    Abstract : This thesis evaluates passive denitrifying woodchip bioreactors (DWBs) for the removal of nitrate (NO3-) in neutral pH mine drainage, where water is passed through a carbon-rich porous matrix (e.g. woodchips) for the reduction of NO3- to nitrogen gas. READ MORE

  3. 3. Generation of Leachate and the Flow Regime in Landfills

    Author : David Bendz; Avdelningen för Teknisk vattenresurslära; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; teknisk geologi; Hydrogeologi; geographical and geological engineering; Hydrogeology; model; transport; flow; leachate; water; hydrology; landfill; MSW; teknisk geografi; Geophysics; physical oceanography; meteorology; Geofysik; fysisk oceanografi; meteorologi;

    Abstract : The environmental impacts of landfills are associated mainly with the emission of leachate and biogas. Sanitary landfilling aims to stabilize the landfill in a efficient and controlled way, so that the environmental impacts are minimized. When a sanitary landfill has attained its final storage quality, it can be integrated into the environment. READ MORE

  4. 4. Removal of Micropollutants from Wastewater : evaluation of effect of upgrading ozonation to electro-peroxone

    Abstract : The United Nations (UN) has adopted 17 “Sustainable Development Goals” (SDGs) to achieve a clean, better and sustainable future. SDG 6 is to ensure that everyone has access to clean water and sanitation by 2030. READ MORE

  5. 5. Hydrodynamic control of retention in heterogeneous aquifers and fractured rock

    Author : Hua Cheng; Vladimir Cvetkovic; Chin-Fu Tsang; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Aquifer; Fracture; groundwater; First-order solution; Monte-Carlo simulation; Nu-clear waste; Heterogeneity; Retention processes; Matrix diffusion; Prediction; Evaluation; Travel time; Flow rate; ; Water engineering; Vattenteknik;

    Abstract : In this thesis, fluid flow and solute transport in heterogeneous aquifers and particularly in frac-tured rock have been investigated using Lagrangian Stochastic Advective-Reaction (LaSAR) framework. The heterogeneity of the aquifer structure or fracture configuration, as well as the various reaction/retention processes have been considered in the modelling approach. READ MORE
