1. Predicting inflow and infiltration to wastewater networks based on temperature measurements
Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för informationsteknologiSammanfattning : Sewer pipelines are deteriorating due to aging and sub optimal material selections, leading to the infiltration of clean ground and rainfall water into the pipes. It is estimated that a significant portion (up to 40-50%) of the water entering wastewater treatment plants is actually clean infiltrated water. LÄS MER
2. Selected PFAS in the water treatment at the waste-to-energy plant in Umeå : Investigating concentration and composition of selected PFAS in different water treatment steps
Master-uppsats, Umeå universitet/Institutionen för ekologi, miljö och geovetenskapSammanfattning : The present study investigated the changes in concentration and composition of five selected PFAS substances in the water treatment at the waste-to-energy plant in Umeå. The five PFAS were PFHxA, PFHpA, PFOA, PFHxS and PFOS. As PFAS exists in a variety of consumer products, they will to some extent end up in waste incineration. LÄS MER
3. Towards Water Resource Recovery Facilities : Environmentally Extended Techno-Economic Assessment of Emerging Sewage Sludge Management Technologies in Sweden
Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknikSammanfattning : Municipal sewage sludge (MSS) management varies widely between countries and legislative regimes. Within the European directive for sewage treatment France applies over half of MSS to arable land, while The Netherlands has banned the practice (Kelessidis et al, 2012). LÄS MER
4. Production of natural pigments from A. platensis grown on wastewater from local treatment facility.
Master-uppsats, Lunds universitet/Teknisk mikrobiologi; Lunds universitet/BioteknikSammanfattning : Although microalgae have been considered for the biological treatment of wastewater since the 1950’s, their potential to efficiently remove pollutants from various streams remains largely untapped and is yet to be utilized at large scale. The production of algal biomass and extraction of high-value compounds has, however, become increasingly popular with large scale farms and biorefineries around the world producing many promising alternatives to petroleum-based products and processes.

5. Investigation on the natural indigo dye for cotton fabric by using supercritical carbon dioxide
Master-uppsats, Högskolan i Borås/Akademin för textil, teknik och ekonomiSammanfattning : Concerns about the environmental impact of the textile industry are increasing, and there is an urgent need to develop and implement sustainable technologies. In particular, the environmental impact of dyeing, which emits a large amount of wastewater and chemicals, is one production process that needs to be resolved. LÄS MER
