1. 1. 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

   University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

   Author : Amanda Carlund; [2023]
   Keywords : ;

   Abstract : 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. READ MORE

3. 2. Production of natural pigments from A. platensis grown on wastewater from local treatment facility.

   University essay from Lunds universitet/Teknisk mikrobiologi; Lunds universitet/Bioteknik

   Author : Hana Faulds; [2023]
   Keywords : Cyanobacteria; pigments; microalgae; wastewater treatment; biotechnology; Technology and Engineering; Biology and Life Sciences;

   Abstract : 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.

4. 3. Finding ways of optimizing coagulant dosage, for a more sustainable wastewater treatment process

   University essay from Lunds universitet/Kemiteknik (CI)

   Author : Hanna Sjöman; [2023]
   Keywords : Wastewater treatment process; coagulant dosage; COD; machine learning; water and environmental engineering; Technology and Engineering;

   Abstract : The wastewater treatment process at Oatly consists of several treatment steps of which, two are chemical treatment steps involving coagulation followed by flotation to remove phosphorous and COD. The coagulant dosage is mainly determined based on the operator’s experience and supported using results from jar tests. READ MORE

5. 4. IMPLEMENTATION OF NITROGEN RECOVERY AT WASTEWATER TREATMENT PLANTS TO COMPLEMENT ARTIFICIAL FERTILISER PRODUCTION : An investigation of the nitrogen recovery potential, energy consumption and environmental impacts at Kungsängens wastewater treatment plant in Västerås, Sweden

   University essay from Mälardalens universitet/Akademin för ekonomi, samhälle och teknik

   Author : Cassandra Kestran; Olivia Larsson; [2023]
   Keywords : Ammonia stripping; Eutrophication; Fertiliser production; Gas permeable membrane; Haber-Bosch; Nitrogen management; Nitrogen recovery technologies; Nitrogen removal; Reject water;

   Abstract : As Kungsängens wastewater treatment plant is considering a move, it opens up a possibility to implement nitrogen recovery technologies that comply with current and future legislative requirements. Nitrogen recovery offers simultaneous treatment of wastewater and collection of concentrated ammonia products for fertiliser production. READ MORE

6. 5. Water quality improvement of highway runoff by the filter material D-Rainclean : A five-month field trial

   University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

   Author : William Gulding; [2023]
   Keywords : Adsorption; D-Rainclean; metal removal; Reactive filter; stormwater treatment;

   Abstract : Highway runoff and its pollutants are of growing concern. These pollutants require treatment as their concentration often are increased. A common removal method is the use of sedimentation ponds that removes particulates through gravity. READ MORE
