16. GAC filter Design Criteria for Wastewater Treatment for Removal of Organic Micropollutants – A Literature Review
Master-uppsats, Lunds universitet/Kemiteknik (CI)Sammanfattning : Granular Activated Carbon (GAC) is nowadays suggested as a fourth (quaternary) treatment step at municipal wastewater treatment plants to remove certain chemicals and particularly organic micropollutants (OMPs). This work investigated the different factors that affect the performance of the GAC filter for the removal of micropollutants in a municipal wastewater treatment plant. LÄS MER
17. Utility of bark chips for removal of fluorinatedorganic compounds in water samples at a hazardouswaste management facility
Kandidat-uppsats, Örebro universitet/Institutionen för naturvetenskap och teknikSammanfattning : Per- and polyfluoroalkyl substances (PFAS) are synthetic compounds that have beenaround since 1940. They can be used in a variety of products such as fire-fighting foam,food packaging and cosmetic products. Many PFAS have potential toxic effects on bothhumans and animals which poses a problem due to their wide distribution and persistency. LÄS MER
18. Separation of Cobalt and Nickel using CYANEX 272 for Solvent Extraction
Master-uppsats, KTH/KemiteknikSammanfattning : This project aimed to examine the separation of cobalt and nickel using solvent extraction (SX) with the extractant CYANEX 272 (C272). It was intended to investigate the Co-Ni separation in a sulphate-based leach solution in presence of other contaminants. LÄS MER
19. Urban stormwater ponds: Evaluation of heavy metals and organic pollutants in stormwater and stormwater sediments
Master-uppsats, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurserSammanfattning : Urban runoff is generated by precipitation of rain and snowmelt on impervious surfaces. The increasing demand of urbanization causes contaminants to accumulate on roads, roofs and pathways. In turn, as runoff wash off these surfaces, contaminants such as heavy metals, particles and organic pollutants end up in the stormwater. LÄS MER
20. Methods for measuring mercury in gas ebullition from fiber banks : A literature study
Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknikSammanfattning : Mercury contamination is an environmental issue with high priority due to its high toxicity. In addition to the atmospheric deposition, several lakes and rivers in Sweden are contaminated as a result from wood and pulp-fiber industries which stretches back 200 years. LÄS MER
