  1. 21. Inter-Calibration of Optical Sensors and Implications for Water Quality Monitoring

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Svenja-Maria Hoffmeister; [2017]
    Keywords : Absorbance; fluorescence; optical sensors; DOC; turbidity; water quality; Absorbans; fluorescens; optiska sensorer; DOC; turbiditet; vattenkvalité;

    Abstract : Expected changes in water quality due to a changing climate associated with variabilities in rainfall, runoff and diffusive spreading of pollution pose an emerging risk for the drinking water supply. Extensive monitoring of water quality parameters is of importance and the possibility of sudden extreme events brings up the need of high-frequency measurements. READ MORE

  3. 22. Techno-Economic Feasibility Study for the Production of Microalgae Based Plant Biostimulant

    University essay from KTH/Skolan för kemivetenskap (CHE)

    Author : Laurent Arnau; [2016]
    Keywords : Biomass; sustainability; photobioreactor; flocculation; centrifugation; sterilization;

    Abstract : Microalgae are considered as a potential feedstock for many promising applications. Some active substances in microalgae have plant biostimulation effects potentially useful in agriculture. However, to produce such a microalgal biomass, specific microalgae cultivation and post-treatment processes must be designed to preserve active substances. READ MORE

  4. 23. Integration of powdered activated carbon in tertiary disc filtration of wastewater

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Elias Thörnqvist; Philip Isgaard; [2016]
    Keywords : vattenförsörjningsteknik; water engineering; environmental engineering; flocculation; coagulation; PAC; disc filter; micropollutants; powdered activated carbon; avloppsteknik; Technology and Engineering;

    Abstract : This thesis investigates the feasibility of integrating Powdered Activated Carbon (PAC) in to chemical treatment in combination with disc filtration of tertiary wastewater. Jar and tube tests have been performed, where the suspension was filtered through a 10 μm disc filter from Hydrotech Veolia Water Technologies. READ MORE

  5. 24. Renewable energy from wastewater grown microalgae - a concept for nutrient recycling and sustainable energy recovery

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Stina Lidén; [2015]
    Keywords : sustainable wastewater treatment; vattenförsörjningsteknik; avloppsteknik; renewable energy; nutrient reduction; nutrient recycling; microalgae; AnMBBR; biogas; Technology and Engineering;

    Abstract : Wastewater is an excellent source of nutrients and energy. By treating the wastewater in a clever way, it is possible to both recycle nutrients and recover energy, and thereby create opportunities for a sustainable system. READ MORE

  6. 25. Energy and nutrient recovery from dairy manure : Process design and economic performance of a farm based system

    University essay from Linköpings universitet/Industriell miljöteknik; Linköpings universitet/Tekniska högskolan

    Author : Filip Celander; Johan Haglund; [2014]
    Keywords : Manure; cattle; fertiliser; nutrient recovery; renewable energy; manure separation; struvite; Stallgödsel; gödsel; gödselseparering; växtnäring; förnyelsebar energi; struvit;

    Abstract : This thesis assessed the technical and economic premises for installing systems that process manure in order to recover nutrients and inherent energy. The main purpose of recovering nutrients was to extract phosphorus from the manure, so as to be able to distribute more of the manure on the farm without exceeding the phosphorus regulation. READ MORE
