1. A study on the effects on a wastewater treatment plant when recovering the heat from the wastewater
Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)Sammanfattning : source of thermal energy. Wastewater as a source of energy has gotten more attention in recent times, as the Sustainable Development Goals in combination with local challenges encourage new technical solutions that can replace old and outdated technology.

2. Evaluation of Carbon Source Addition on Denitrification Efficiency : A study in a continuous biological leachate water treatment system.
Master-uppsats, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)Sammanfattning : In 2014 SÖRAB constructed a continuous biological treatment system (KBR) to handle leachate waterfrom the landfill at the facility in Löt, north of Stockholm. The KBR is mainly focused on removal ofammonium nitrogen which would otherwise be released in to the recipient and contribute toeutrophication and damage to the environment. LÄS MER
3. Volatile fatty acid production from co-fermentation of primary sludge and food waste without pH control
Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknikSammanfattning : The production of volatile fatty acids (VFAs) from waste stream is gaining high attention because of their high market value and wide range of applications. In this study, the production of VFA from co-fermentation of primary sludge from wastewater treatment plant and food waste without pH control was evaluated using a pilot-scale reactor in a semi-continuous mode of operation.

4. Causes and impact of surface water pollution in Addis Ababa, Ethiopia
Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för geovetenskaperSammanfattning : Surface water is globally becoming more and more a scarce resource, and in Addis Ababa the capital of Ethiopia, river water quality has been degraded due to anthropological forcing for many years. Therefore, the study objective was to investigate causes and impact of surface water pollution in Kebena and Great Akaki rivers. LÄS MER
5. Reningstekniker för reducering av ammoniumkväve i rökgaskondensat.
Kandidat-uppsats, Linnéuniversitetet/Institutionen för biologi och miljö (BOM)Sammanfattning : Utsläpp av kväveoxider (NOx) från förbränningsanläggningar har kraftigt minskat sedan kväveoxidavgiften infördes. Berörda anläggningar använder därför oftast rökgasrening med selektiv icke-katalytisk reduktion (SNCR). Metoden innebär att man tillsätter ammoniak i rökgaserna för att reducera NOx-halterna. LÄS MER
