1. Wastewater Treatment at Kraft Pulp Mills : Effect of temporary effluents and mitigation measures
Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurserSammanfattning : Large amount of water is used in the pulp-and-paper industry. Consequently, large amount of wastewater is produced in the various production processes. In general, the pollutants of concern involve organic compounds, nutrients, including nitrogen and phosphorous, suspended solids, and chlorinated compounds. LÄS MER
2. The possibilities of recycling wash water at Vidinge
Master-uppsats, Lunds universitet/Kemiteknik (CI)Sammanfattning : Water is a resource of importance and with drier weather around the world, including Swe-den, there is a risk of too low levels of water to satisfy for instance households, animals and industries in the future. Fresh-cut fruit and vegetable industries are water intense and almost all process water is used in the washing process. LÄS MER
3. Evaluation of stimulated reductivedechlorination in situ of chlorinatedsolvents at a site in Huddinge : using principal component analysis, partialleast square regression and degradation
Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för geovetenskaperSammanfattning : The method of using stimulated reductive dechlorination when remediating sites contaminated with chlorinated solvents is not unusual, but not many studies have been done on the overall process outside of a controlled environment. In order to investigate the process, principal component analysis (PCA) and partial least square (PLS) regression was used to identify the most important parameters for the degradation of the chlorinated solvents.

4. Application of ERT and IP for localisation of chlorinated hydrocarbons at a former dry-cleaning facility
Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Teknisk geologi; Lunds universitet/Väg- och vattenbyggnad (CI)Sammanfattning : At Hagforstvätten a dry-cleaning facility operated 1970 – 1993 and leached huge amounts of tetrachloroethene (PCE) to soil and groundwater. This study was conducted at the contaminated site and focused on applying the geophysical methods Electrical Resistivity Tomography (ERT) and Induced Polarization (IP) to investigate if it was possible to locate source zone, degradation zones and groundwater plumes of PCE.

5. Framtagande av platsspecifik grundvattenmodell samt modellering av klorerade lösningsmedels spridning i grundvatten kring industritomt : – Utvärdering av nuvarande samt framtida föroreningssituation
Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Luft-, vatten- och landskapsläraSammanfattning : One of the Government's environmental quality objectives is to achieve a poison free environment, meaning that the presence of anthropogenic substances in the environment should not pose a threat to human health or biodiversity. Such a substance is chlorinated aliphatic hydrocarbons which have been used historically in dry cleaning and as degreasing agents within industrial processes. LÄS MER
