1. 1. Wastewater Treatment at Kraft Pulp Mills : Effect of temporary effluents and mitigation measures

   University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

   Author : Hodda Shariatmadari; [2023]
   Keywords : ;

   Abstract : 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. READ MORE

3. 2. The possibilities of recycling wash water at Vidinge

   University essay from Lunds universitet/Kemiteknik (CI)

   Author : Julia Mauritzson; [2020]
   Keywords : reuse; treatment; fresh-cut; water engineering; environmental engineering; avloppsteknik; vattenförsörjningsteknik; Technology and Engineering;

   Abstract : 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. READ MORE

4. 3. Evaluation of stimulated reductivedechlorination in situ of chlorinatedsolvents at a site in Huddinge : using principal component analysis, partialleast square regression and degradation

   University essay from Uppsala universitet/Institutionen för geovetenskaper

   Author : Karin Ljungberg; [2018]
   Keywords : Reductive dechlorination; DNAPL; stimulated bioremediation; chlorinated solvents; Reduktiv deklorering; DNAPLS; stimulerad biologisk behandling; klorerade lösningsmedel;

   Abstract : 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.

5. 4. Application of ERT and IP for localisation of chlorinated hydrocarbons at a former dry-cleaning facility

   University essay from Lunds universitet/Teknisk geologi; Lunds universitet/Väg- och vattenbyggnad (CI)

   Author : Hedda Jönsson; Anna Wiberg; [2017]
   Keywords : Chlorinated hydrocarbons; PCE; Hagforstvätten; Geophysics; Resistivity; Chargeability; Geological features; Man-made structures; Technology and Engineering; Earth and Environmental Sciences;

   Abstract : 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.

6. 5. GC-MS Screening and PCB Analysis of Sediment from Central Kattegat

   University essay from Örebro universitet/Institutionen för naturvetenskap och teknik

   Author : Emma Eriksson; [2015]
   Keywords : Paper mill; nuclear power plant; screening; GC-MS; PCB; APGC;

   Abstract : Five sediment samples were collected in Bua on the Swedish west coast, near two industries, a paper mill, and a nuclear power plant. The two industries use water in their processes and have long been associated with releases of different substances, such as PCBs, and other chlorinated compounds. READ MORE
