  1. 1. Disinfection of Wastewater with Sodium Hypochlorite : And how it Might be Applied at Slottshagen Wastewater Treatment Plant

    University essay from Linköpings universitet/Institutionen för fysik, kemi och biologi

    Author : Emmy Johansson; [2021]
    Keywords : Disinfection; Sodium hypochlorite; Wastewater;

    Abstract : The disinfection of wastewater is not something that is currently in use at any wastewater treatmentplant in Sweden. The government has however stated some requirements for some wastewatertreatment plants to have a plan to implement disinfection in their treatment process, if asked. READ MORE

  3. 2. Analyzing microplastics in soils : Evaluating canola oil extractions

    University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Author : Anna Bottone; [2019]
    Keywords : Microplastics; extraction recovery; OEP method; organic-rich soils;

    Abstract : Small fragments of artificial polymers (microplastics, MPs) has been reported for multiple environmental matrices from our planet. The omnipresent existence of these microplastics even in remote polar areas have raised concern about their potential environmental impacts and created a need for effective and standardized analytical methods targeting their detection in environmental samples.

  4. 3. Bioplastic material from microalgae : Extraction of starch and PHA from microalgae to create a bioplastic material

    University essay from KTH/Materialvetenskap

    Author : Nathalie Johnsson; Fredrik Steuer; [2018]
    Keywords : Bioplastic material; Starch; PHA; PH3B; Extraction; Microalgae; Polymers; Bioplastiskt material; Stärkelse; PHA; PH3B; Extraktion; Mikroalger; Polymerer;

    Abstract : Microalgae used in sewers to capture CO2 eventually turns into waste material. Through the use oftheir biomass, the waste algae can be given a new purpose. In this study attempts to extract starch or PHA from three different algae; Calothrix Scytonemicola, Scenedesmus Almeriensis and Neochloris Oleoabundans, were made. READ MORE

  5. 4. Inactivation of viruses in water by chlorination using bacteriophages as model organisms

    University essay from SLU/Dept. of Biomedical Sciences and Veterinary Public Health

    Author : Charan Raju Kanna; [2016]
    Keywords : desinfection; chlorination; bacteriophages; viruses; free chlorine;

    Abstract : Climate change will lead to more extreme rain events in parts of Sweden resulting in sewage overflows and thus more contamination of surface water, leading to an increased risk of waterborne infections. Swedish and Norwegian surface waters are rich in humic substances with high organic carbon content that interferes with disinfection, the most important barrier to viruses in the water treatment plant.

  6. 5. Production of Dialdehyde Cellulose and Periodate Regeneration: Towards feasible oxidation processes

    University essay from Karlstads universitet/Institutionen för ingenjörs- och kemivetenskaper

    Author : Elisabeth Höglund; [2015]
    Keywords : Dialdehyde cellulose; periodate regeneration;

    Abstract : Cellulose is an attractive raw material that has lately become more interesting thanks to its degradability and renewability and the environmental awareness of our society. With the intention to find new material properties and applications, studies on cellulose derivatization have increased. READ MORE
