  1. 21. Evaluation of degree of phosphorus saturation (DPS) and easily soluble P in top- and subsoil as a predictor for P-leaching

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Jessie Torpner; [2019]
    Keywords : degree of phosphorus saturation; dissolved reactive phosphorus; easily soluble P; column experiment; lactate extracted P;

    Abstract : Eutrophication has long been an environmental problem and the effects from fertilizingarable land is a known source. The degree of phosphorus saturation (DPS)and easily soluble phosphorus (P) are different variables used in different countriesto try to predict the leaching of P from soils. READ MORE

  3. 22. Towards autonomous antibody purification

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Frida Heskebeck; [2019]
    Keywords : Chemical engineering; Kemiteknik; Simulation; Chromatography; Periodic counter-current chromatography; Python; PCC; Technology and Engineering;

    Abstract : The vision of antibody purification is to have the whole process fully automatic. It is often desirable to have a continuous process since that reduces the costs for production and the size of the used equipment. It is necessary to supply buffer solutions to the purification steps, and as part of the vision; this should be done automatically. READ MORE

  4. 23. Possibilities for removal of micropollutants in small-scale wastewater treatment - methods and multi-criteria analysis

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Anqi Li; [2018]
    Keywords : pharmaceuticals; column experiment; removal efficiency; absorbents;

    Abstract : The quality of worlds’ water resources is facing new challenges, for instance detectable concentration of various trace contaminants under the term micropollutants is discharging into water bodies from both municipal wastewater treatment plants and from on-site wastewater facilities. A project called RedMic aim at identifying and quantifying emissions of micropollutants from on-site wastewater treatments as a basis for providing innovative treatment technologies to reduce potential risks for groundwater and surface water contamination.

  5. 24. The Effect of Photobacterium damselae Availability on the Behavior of Choanocytes in the Marine Sponge Amphimedon queenslandica

    University essay from Lunds universitet/Examensarbeten i biologi

    Author : Mathias Jönsson; [2018]
    Keywords : Biology and Life Sciences;

    Abstract : Sponges are aquatic filter feeding animals that use internal chambers comprised of choanoflagellate-like cells called choanocytes to pump and filter water. In this study I investigated the behavior of choanocytes in juvenile Amphimedon queenslandica, a coral reef demosponge, when they were fed Photobacterium damselae subsp. READ MORE

  6. 25. Wastewater treatment with nanofiltration in pilot-scale

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Jane Quach; Safa al Basheer; [2018]
    Keywords : wastewater; nanofiltration; ultrafiltration; chemical precipitation; pilot-scale; chemical engineering; kemiteknik; Technology and Engineering;

    Abstract : During the spring semester 2018, an investigation about supplementary cleaning of the waste water at Dow Chemical site in Landskrona was done. Different water-based binders from acrylic monomers are produced by Dow and large amounts of water is used for such processes. READ MORE
