   Author : Koustubh Karande; [2022]
   Keywords : Wastewater treatment; Dissolved organic matter; Pharmaceuticals; Activated carbon; Hydrophobicity; Molecular weight; Water resources engineering; Technology and Engineering;

   Abstract : Micropollutants in our sources of freshwater is an issue which requires immediate attention. The presence of pharmaceuticals, endocrine disrupting agents, pesticides and other harmful compounds have proven to have impact on the aquatic as well as on human life. READ MORE

3. 22. Purification of Volatile Organic Compounds in Channeled Ventilation Pipes at the Sysav Water Treatment Plant for Hazardous Waste

   University essay from Lunds universitet/Kemiteknik (CI)

   Author : Erik Wiktorsson; [2022]
   Keywords : VOC; Zeolite; Catalytic combustion; Sysav; Chemical Engineering; Chemistry; Technology and Engineering;

   Abstract : Several channeled emissions at the Sysav water treatment plant for hazardous waste as of December 2021 exceed permitted levels of unknown volatile organic compounds (VOCs) stated in the European Parliament councils’ directives 2010/75/EU. A range of possible treatment methods are briefly discussed before zeolite adsorption, and thermal regeneration followed by catalytic combustion is decided to be the method of greatest feasibility and is the subject of further investigation.

5. 24. Evaluation of PFAS removal from nanofiltration membrane concentrate using foam fractionation

   University essay from Uppsala universitet/Institutionen för geovetenskaper

   Author : William Stefansson; [2022]
   Keywords : PFAS; Aeration foam fractionation; Nanofiltration membrane; DWTP; Surfactant; PFAS; Skumfraktionering; Nanofiltration; Vattenverk; Surfaktant;

   Abstract : Per- and polyfluorinated substances (PFASs) have become an urgent topic in the water treatment industry in recent years as a consequence of new scientific discoveries of the correlation between the ingestion of some PFASs and their toxicity in humans and other organisms. PFASs are synthetic compounds present in a variety of products. READ MORE

6. 25. Influence of Humidity Over the Properties of Wood Fiber-based Biocomposites

   University essay from KTH/Fiber- och polymerteknologi

   Author : Arvid Hedin; Anna Kudinova; Linnea Masso; [2022]
   Keywords : Wood Polymer Composite; WPC; Relative Humidity; RH; Tensile Testing; Polypropene; FibraQ; Wood Fiber; Surface Treatment; Mechanical Properties;

   Abstract : The project aims to develop a methodology to study the variation in properties of wood polymer composites (WPC’s) with/without surface treatment at different humidity conditions. The project aims to investigate the behavior of biocomposites at 50%, 80%and 100% relative humidity (RH). READ MORE
