  1. 1. Fault Detection in Wastewater Treatment : Process Supervision to Improve Wastewater Reuse

    Author : Heidi Lynn Ivan; Monica Odlare; Valentina Zaccaria; Jan Skvaril; Tiina Komulainen; Mälardalens universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wastewater treatment; Process supervision; Fault Detection; Energy- and Environmental Engineering; energi- och miljöteknik;

    Abstract : As wastewater treatment plants transition to water resource recovery facilities, the need for improved control and consequently supervision increases. Despite the large volume of research that has been performed on this topic, the use in industry is scarce. READ MORE

  2. 2. Enhanced phosphorus removal from wastewater using virgin and modified slags : performance, speciation and mechanisms

    Author : Minyu Zuo; Gunno Renman; Jon Petter Gustafsson; Lars Lövgren; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; AOD; EAF; BFS; Calcium phosphate; XANES; slag mineralogy; Mark- och vattenteknik; Land and Water Resources Engineering;

    Abstract : Argon oxygen decarburization slag (AOD) was tested in batch and column experiments to investigate its phosphorus (P) removal performance. The effects of factors such as AOD dose, initial P concentration of the feeding solution, and aging on the P removal ability of the slags were analyzed. READ MORE

  3. 3. Investigation of nitrogen recovery from concentrated wastewater

    Author : Aubrey Beckinghausen; Monica Odlare; Eva Thorin; Sebastian Schwede; Ershad Ullah Khan; Mälardalens universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; nitrogen; ammonium; recovery; circular economy; wastewater; Energy- and Environmental Engineering; energi- och miljöteknik;

    Abstract : Nitrogen recovery from wastewater treatment for fertilizers is a research topic that exists at the intersection of multiple topics important to the future of sustainable society. First, nitrogen recovery from wastewater implies a departure from the current methods of nitrogen mitigation, which involve nitrogen removal by conversion of various aqueous species to inert nitrogen gas.

  4. 4. A small scale wastewater treatment system adapted to nutrient recovery in cold climate : performance and possible sorbents

    Author : Lea Rastas Amofah; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; VA-teknik; Urban Water Engineering;

    Abstract : Waterbodies are impaired by, among other things, discharge from onsite small- scale wastewater (WW) treatment systems. Hence, these systems need to be updated to improve the effluent quality and the reuse of nutrients within society. READ MORE

  5. 5. Wastewater treatment and biomass generation by Nordic microalgae : growth in subarctic climate and microbial interactions

    Author : Lorenza Ferro; Christiane Funk; Francesco Gentili; Luísa Gouveia; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Microalgae; Wastewater; Nitrogen; Phosphate; Biomass; Lipids; Subarctic Climate; Light; Temperature; Bacteria; Photoautotrophy; Heterotrophy; Mixotrophy; HRAP; Metabarcoding; Microbial Communities; Alpha-diversity; Environmental Factors; Biochemistry; biokemi; mikrobiologi; Microbiology;

    Abstract : Nordic native microalgal strains were isolated, genetically classified and tested for their ability to grow in municipal wastewater. Eight of the isolated strains could efficiently remove nitrogen and phosphate in less than two weeks. Two of these strains, Coelastrella sp. READ MORE
