    Keywords : 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;

    Abstract : 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. READ MORE

  2. 2. Model of Thermal EHL Based on Navier-Stokes Equations : Effects of Asperities and Extreme Loads

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Marko Tošić; [2019]
    Keywords : ;

    Abstract : A common approach in numerical studies of elastohydrodynamic lubrication (EHL) is based on solving the Reynolds equation that governs pressure distribution in thin lubricant films. The Reynolds equation is derived from the Navier-Stokes equations by taking assumptions that are considered valid when the thickness of the lubricant film is much smaller than its length. READ MORE

  3. 3. Analysis of hydrogels for immobilisation of hepatocytes (HepG2) in 3D cell culturing systems

    University essay from Linköpings universitet/Teknisk biologi

    Author : Elisabeth Westergren; [2018]
    Keywords : Hydrogel; Hepatocyte; Tuneable; PEG-peptide; 3D cell culture;

    Abstract : In pharmaceutical development cell cultures are used as in vitro models to evaluate the function of drug candidates. In such research it is vital to have models that resemble the in vivo environment to get reliable results. READ MORE

  4. 4. Investigation of the shear strength of silica sol - Laboratory studies of a grouting agent using mechanical, rheological and hydraulic tests

    University essay from Chalmers tekniska högskola/Institutionen för arkitektur och samhällsbyggnadsteknik

  5. 5. A rheological study of hyaluronan and sodium hydroxide at different concentrations

    University essay from Uppsala universitet/Institutionen för teknikvetenskaper; Uppsala universitet/Institutionen för teknikvetenskaper; Uppsala universitet/Institutionen för teknikvetenskaper; Uppsala universitet/Institutionen för teknikvetenskaper; Uppsala universitet/Institutionen för teknikvetenskaper

    Author : Natalia Gentek; Melissa Jöe; Sofia Lindell; Karin Norgren; Ellen Sjövall; [2018]
    Keywords : hyaluronan; hyaluronic acid; sodium hydroxide; rheology; fluid; elastic modulus; loss modulus;

    Abstract : This thesis examines how the rheological properties change depending on the composition of hyaluronan, HA and sodium hydroxide, NaOH. This was performed to see if there was any relationship between the rheological properties of a sample depending on different compositions of HA and NaOH. READ MORE
