1. 1. Microsieving in municipal wastewater treatment : Chemically enhanced primary and tertiary treatment

   Författare :Janne Väänänen; Avdelningen för kemiteknik; []
   Nyckelord :coagulation; wastewater treatment; flocculation; microsieving; control; primary treatment; tertiary treatment; coagulation; control; flocculation; microsieving; municipal wastewater treatment; primary treatment; tertiary treatment;

   Sammanfattning : Municipal wastewater treatment plants are constantly forced to make improvements. The main objectives are to reduce energy consumption, to increase the treatment capacity and to improve the effluent water quality. Microsieves in combination with chemical pretreatment can potentially fulfil these objectives. LÄS MER

3. 2. Towards application of activated carbon treatment for pharmaceutical removal in municipal wastewater

   Författare :Victor Kårelid; Gen Larsson; Gunno Renman; Ola Svahn; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; advanced wastewater treatment; granular activated carbon; powdered activated carbon; municipal wastewater treatment; pharmaceutical removal; Bioteknologi; Biotechnology;

   Sammanfattning : Many pharmaceuticals are found in municipal wastewater effluents due to their persistence in the human body as well as in conventional wastewater treatment processes. This discharge to the environment can lead to adverse effects in aquatic species, such as feminization of male fish. LÄS MER

4. 3. Antimicrobials in sewage treatment plants : occurrence, fate and resistance

   Författare :Marcus Östman; Mats Tysklind; Jerker Fick; Erik Björn; Klaus Kümmerer; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; biocides; antibiotics; sewage treatment plants; wastewater; sludge; ozonation; activated carbon; antibiotic resistance; antimicrobials; mass flows; LC-MS MS; environment; advanced water treatment;

   Sammanfattning : The World Health Organization (WHO) has identified antibiotic resistance as a major threat to human health. The environment has been suggested to play an important role in the emergence of antibiotic resistant bacteria. The external environment can act as a source of resistance genes that could potentially be transferred into human pathogens. LÄS MER

5. 4. Treatment of Textile Wastewater by Combining Biological Processes and Advanced Oxidation

   Författare :Marisa Punzi; Bioteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Azo dye; textile wastewater; biological treatment; biofilm; microbial community; DGGE; green algae; photo-Fenton; ozone; toxicity; mutagenicity; LCA; cost analysis;

   Sammanfattning : Treatment of textile wastewater is challenging because the water contains toxic compounds that have low biodegradability. Dyes, detergents, surfactants, biocides and more are used to improve the textile process and to make the clothes resistant to physical, chemical and biological agents. LÄS MER

7. 5. Removal of Micropollutants from Wastewater : evaluation of effect of upgrading ozonation to electro-peroxone

   Författare :Majid Mustafa; Mats Tysklind; Daniel Ragnvaldsson; Lars Lövgren; Santiago Esplugas; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electro-peroxone; ozone; hydroxyl radicals; advanced oxidation processes; pharmaceuticals; QSAR; biocides; wastewater; removal; predictions; water matrix; activated carbon; sorption; regeneration; environmental science; miljövetenskap;

   Sammanfattning : The United Nations (UN) has adopted 17 “Sustainable Development Goals” (SDGs) to achieve a clean, better and sustainable future. SDG 6 is to ensure that everyone has access to clean water and sanitation by 2030. LÄS MER
