1. 1. Techno-Economic Analysis of Dye Separation in Textile Recycling

   University essay from Lunds universitet/Avdelningen för Teknisk vattenresurslära

   Author : David Lundberg; [2024]
   Keywords : Dye; Membrane filtration; Electrocoagulation; Techno-economic analysis; Pre-feasibility study; Technology and Engineering;

   Abstract : This study determines the technical and economic feasibility of separating dye from a process filtrate in industrial textile recycling using electrocoagulation or sequences of membrane filtration with microfiltration, ultrafiltration, nanofiltration and reverse osmosis. The lower requirements for treating this stream, compared to previously researched dyehouse effluents, left treatments not good enough for dyehouses viable for this process filtrate. READ MORE

3. 2. Identifying factors that correlate with Enhanced Biological Phosphorus Removal upsets at Lundåkraverket

   University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

   Author : Rounak Niranjan; [2021]
   Keywords : Enhanced biological phosphorus removal; polyphosphate accumulating organisms; glycogen accumulating organisms; sludge content in aeration basin; nitrates in aeration basin; pH of incoming water; principal component analysis; pairwise correlations; inhibition factors;

   Abstract : The Enhanced Biological Phosphorus Removal (EBPR) process is characterized as the most sustainable process to remove phosphorus from wastewater albeit with high variability in performance efficiency. Thus, unpredictable upsets in the EBPR system is the norm across several wastewater treatment plants throughout Sweden, forcing the hand of the operators to dose higher volume of chemicals to reach the effluent requirements.

4. 3. 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

5. 4. Study of Nitrogen Removal Rate and Trouble shooting of Pilot plant (ITEST).

   University essay from KTH/Mark- och vattenteknik

   Author : Venkata Krishna Reddy Yatham; [2012]
   Keywords : Nitrification; Denitrification; Eutrophication; Activated sludge processes; Temperature; pH; Cuvette and Spectrophotometer;

   Abstract : This paper is about improving the efficiency of nitrogen and other organic nutrient removal from activated sewage treatment by adopting an innovative technology. The work is to study the changes in nitrogen removal in pilot-scale experiments with the ITEST unit. READ MORE

6. 5. Urban stormwater management: : Optimization of the treatment of stormwater in urban areas

   University essay from KTH/Industriell ekologi

   Author : Yoann Regent; [2010]
   Keywords : stormwater management; stormwater treatment; Mulden-Rigolen system; Germany; soil contamination;

   Abstract : The Mulden-Rigolen system, a new urban stormwater management system implemented in Germany, has been examined in this study. The aim of this new system is to replace traditional sewer system for urban road runoff, by infiltrating the incoming water locally through a dual underground system: an active top soil layer and a deeper trench of packed gravel.
