1. 16. Treatment of dissolved metals in highway runoff water : Pilot-scale trial with four reactive filter media and sand filter

   University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

   Author : Serena Bianchi; [2021]
   Keywords : stormwater treatment; metal removal; adsorption; reactive filter media; sand filtration; Petrit-T; Polonite; D-Rainclean; Filtralite-P; de-icing salt; pressure drop; filter clogging; rening av dagvatten; avl ̈agsnande av metaller; adsorption; reaktiva filterme- dier; sandfiltrering; Petrit-T; Polonite; D-Rainclean; Filtralite-P; avisningssalt; tryckfall; filterstoppning;

   Abstract : The increasing highway traffic is leading to higher and higher levels of pollutants in the stormwater, such as suspended solids, metals, oils, nutrients and PAH. This runoff water causes the degradation of water bodies quality, leading to increased interest in the treatment of highway runoff for the removal of contaminants. READ MORE

3. 17. Modelling control strategies for chemical phosphorus removal at Tivoli wastewater treatment plant

   University essay from Uppsala universitet/Institutionen för geovetenskaper

   Author : Sara Rosendahl; [2021]
   Keywords : Wastewater treatment plant; phosphorus precipitation; control strategy; feedforward; feedback; ASM2d and primary clarifier model.;

   Abstract : Wastewater compose an environmental risk as it contains high levels of nutrients, including phosphorus. Wastewater treatment plants (WWTPs) reduce phosphorus by using coagulants that precipitate soluble phosphate into metal phosphate, which is separated by settling. READ MORE

4. 18. Evaluation of a gross pollutant trap-biofilter stormwater treatment train : The Role Of Calcium Carbonate, Vegetation And Pre-Treatment Facility

   University essay from Luleå tekniska universitet/Arkitektur och vatten

   Author : Sofia Fahlbeck Carlsson; [2021]
   Keywords : Bioretention; stormwater; stormwater treatment; stormwater pollutants; heavy metals; phosphorus; Biofilter; dagvatten; dagvattenrening; dagvattenföroreningar; tungmetaller; fosfor;

   Abstract : Development of cities, new buildings and other impervious surfaces entails increased stormwater flows, volumes and pollutant loads. Heavy metals, nutrients, sediments and salt are common pollutants in stormwater. READ MORE

5. 19. Hydrolysis of waste activated sludge from pulp and paper mills : effect on dewatering properties and biogas potential by utilizing existing side streams

   University essay from Linköpings universitet/Tema Miljöförändring

   Author : Louise Hjalmarsson; [2021]
   Keywords : hydrolysis; dewatering properties; biogas; sludge; waste activated sludge;

   Abstract : A big challenge within pulp and paper mills is the large quantities of waste activated sludge (WAS) that is produced during the wastewater treatment. The WAS is made up of biological cells and extra polymeric substances (EPS) and can bind a large amount of water causing difficulties to dewater the WAS. READ MORE

6. 20. Assessment of on-site wastewater treatment systems in unsewered communities in Jordan

   University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

   Author : Hani Yahya Ali Shubail; [2020]
   Keywords : Constructed wetland; Decentralized wastewater treatment; Jordan; On-site wastewater treatment system;

   Abstract : Centralized wastewater treatment systems need substantial funds besides high-cost operation and maintenance programs, which could be considered unsuitable for low-income developing countries. As a solution, it becomes the trend towards on-site wastewater treatment systems (OWTs) due to its cost-effectiveness and flexibility of implementation and management. READ MORE
