1. 1. Lifetime CostEffectiveness of Constructed Wetland and Rain Garden Facilities in Relation to Expected  Treatment Performance

   University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

   Author : Abdullah Noorhussin Ali; [2023]
   Keywords : Stormwater; Total cost; StormTac; Cost-effectiveness;

   Abstract : The purpose of this thesis is to investigate the cost effectiveness of two different stormwater control measure (SCM) facilities, namely a constructed wetland in Boden and a rain garden in Gothenburg (both Sweden), in relation to treatment efficiency and contributing catchment area. The study approach involved collection of data, construction, and maintenance activities with their respective costs, for the two stormwater control measures from commercial and literature data.

3. 2. Evaluation of pollutant removal performance of stormwater biofilters in a Swedish climate : Comparison of three different filter media designs

   University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

   Author : Anna Träff; [2022]
   Keywords : Stormwater biofilter; stormwater treatment; cold climate; filter media design; low impact development;

   Abstract : In the recent century, a process of urbanization has increased globally. Previously rural or natural land have been converted into impervious surfaces to make way for housing, industries, and roads. This anthropogenic process has resulted in an increased amount of surface runoff from precipitation, so-called stormwater. READ MORE

4. 3. Metal Removal Efficiency of Five Filter Media Intended for use in Road Stormwater Treatment Facilities

   University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

   Author : Lovisa Lundgren; [2021]
   Keywords : Stormwater; Metal removal efficiency; Filter media; Dagvatten; Metallavskiljningskapacitet; Filtermaterial;

   Abstract : Roads, buildings, vehicles, and human activities cause spreading of pollutants, which partly end up in stormwater. The pollutant load contains solid particles of various size, hydrocarbons, organics, metals, nutrients, and microorganisms, which can have negative effects on water quality of surface-, coastal- and ground waters.

   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

6. 5. Sustainable flue-gas quench : For waste incineration plants within a water-energy-environment nexus perspective

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

   Author : Emad Al Hamrani; Nils Grönberg; [2017]
   Keywords : Biomass waste fuel power plant; pollutant emissions; acid scrubber; ammonia; wastewater; flue gas condenser;

   Abstract : The function of a flue-gas quench is to remove additional contaminants from flue-gas and to reduce the wastewater from a waste incineration plant. The aim of this degree project is to find how the system is affected by using a quench and what factors limits the performance. READ MORE
