  1. 1. Methods for Evaluating Dewatering Properties of Sewage Sludge

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Nadia Abdalla; [2019]
    Nyckelord :sludge dewatering; sewage sludge; laboratory scale sludge treatment; dewatering sludge; dewatering sewage sludge; CST; capillary suction time test; centrifuge; lab-centrifuge; rheology; polymers conditioning; sludge conditioning; centrifuge on lab scale; evaluation of lab experiments; CST evaluation; mechanical de-watering evaluation; sludge dewatering at lab; lab scale dewatering process; sludge dewatering methods at lab; Chemical engineering; Lab centrifuge; Capillary Suction Time CST ; Mechanical sludge dewatering evaluation; Polymers conditioning of sludge; sewage sludge dewatering; methods for sludge dewatering at lab; water engineering; environmental engineering; vattenförsörjningsteknik; avloppsteknik; Chemistry;

    Sammanfattning : After the sewage wastewater is collected from different households and directed to the treatment plants, it goes through several processes, which are physical, chemical and biological. The different processes remove the contaminant, and produce a semi-solid material named sludge. Sludge has a huge amount of liquid. LÄS MER

  2. 2. Automated Simulation and Parameter Estimation of Chromatography Processes

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Johan Olsson; [2019]
    Nyckelord :chemical engineering; kemiteknik; Technology and Engineering;

    Sammanfattning : Preparative chromatography is an important separation technique in downstream processing for several industries. It has the ability to separate two or more component from each other to achieve high purity. LÄS MER

  3. 3. Effects on wastewater due to new active pharmaceutical ingredients and products

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Marina Vik; [2019]
    Nyckelord :Pharmaceutical wastewater; wastewater treatments; BOD; COD; chemical engineering; kemiteknik; Earth and Environmental Sciences; Technology and Engineering;

    Sammanfattning : Wastewater from pharmaceutical industries can sometimes contain substances that could cause complications in the receiving wastewater treatment plant. This master thesis is about a phar-maceutical company and the wastewater from it. LÄS MER

  4. 4. Dose-response for predicting skin sensitization potency with the GARD®skin method

    Master-uppsats, Lunds universitet/Institutionen för Immunteknologi

    Författare :Olivia Eliasson; [2019]
    Nyckelord :Dose-response; In vitro assay; GARD; skin sensitization; allergic contact dermatitis; chemical sensitizers; hazard assessment; skin sensitization potency; immunotoxicology; Technology and Engineering; Biology and Life Sciences;

    Sammanfattning : Allergic contacts dermatitis is a major health problem in the world and the disease is caused by a type IV hypersensitivity to a small chemical called a hapten. These substances are common in cosmetics, perfumes, pharmaceuticals and house-hold products, and risk factors include both inherent factors and frequent or high exposure. LÄS MER

  5. 5. Fractionation of NOM in water from the treatment process at Ringsjöverket

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Stina Karlsson; [2018]
    Nyckelord :water engineering; environmental engineering; avloppsteknik; Technology and Engineering;

    Sammanfattning : During the last decades, increased concentrations of natural organic matter (NOM) and colour of surface waters have been reported from northern Europe and North America. Since surface waters are widely used for drinking water production this development has been problematic for drinking water producers. LÄS MER
