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. Relations between intracellular pH and gamma-aminobutyric acid levels in tea (Camellia sinensis) leaves, after two types of anaerobic treatment

   University essay from SLU/Dept. Of Plant Biology

   Author : Mingmin Tao; [2023]
   Keywords : tea leaves; intracellular pH; gamma-aminobutyric acid; glutamate; decarboxylase; fluorescent dye;

   Abstract : Tea (Camellia sinensis) is one of the three major non-alcoholic beverages in the world. In Gabaron tea, the levels of γ-aminobutyric acid (GABA) are more than 1.3 mg/g. In the human body, GABA lowers blood pressure and cholesterol levels. READ MORE

4. 3. Towards finding model pollutants for predicting CEC adsorption on biochars : The suitability of using dyes as proxies for CEC removal efficiency to enable wastewater reuse

   University essay from Umeå universitet/Kemiska institutionen

   Author : Alexandra Aveling; [2022]
   Keywords : ;

   Abstract : This study evaluated the use of common dyes as model pollutants for adsorption on biochar. Pollutant removal efficiency of five dyes and three CECs on three different biochars (SWP-550, SWP-700, NDG-SW) was evaluated, using both UV-VIS spectrophotometry and LC-MS/MS, to examine similarities and differences in adsorption performance.

   Author : Nils Sjöqvist; [2019]
   Keywords : ;

   Abstract : This thesis evaluates the product to product changeover process of the line S10 at the Coca-Cola European Partners manufacturing plant in Jordbro, Sweden. The target has been to propose improvements to reduce the total planned downtime by 10%. The total planned downtime in March of 2019 was 4449 minutes. READ MORE

6. 5. About Solving and Dissolving : Investigating the design possibilities of bio plastic

   University essay from Högskolan i Borås/Akademin för textil, teknik och ekonomi

   Author : Tanja Marie Nitsche; [2018]
   Keywords : Biomorph; bio plastic; plant dye; surface design; sustainability; textile design; transparency;

   Abstract : Translating the conceptual term of sustainability into materials and exploring bio plastics in order to generate visually and tacitly intriguing objects are the aims for this project. Other designers and previous projects in the field of textile design showed how the material works in a small scale. READ MORE
