  1. 16. Modeling & Simulation of Affinity Chromatography & Investigation of CaptureSMB

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Dennis Bogren; [2018]
    Keywords : Affinity chromatography; simulation of chromatography; breakthrough curve; CaptureSMB; chemical engineering; kemiteknik; Technology and Engineering;

    Abstract : Chromatography was first described in the 1903 by a Russian scientist. Later on chromatography was almost forgotten until the 1940s when two British scientist published a study about liquid chromatography. They were later awarded with the Nobel prize in chemistry for their work in chromatography. READ MORE

  3. 17. Evaluation of Partial Nitritation/Anammox processes operated in IFAS mode

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Aleksandra Zdyrska; [2017]
    Keywords : ;

    Abstract : The main aim of the study was to optimize Partial Nitritation/Anammox process operated in pilot-scale integrated fixed film activated sludge (IFAS) mode supplied with low-temperature mainstream wastewater and efficiency evaluation based on laboratory analysis and data from online sensors. Main tasks of research work were to stabilize the ongoing process and find the optimal conditions for maximizing effects of nitrogen removal. READ MORE

  4. 18. Automated hydroponics greenhouse : Regulation of pH and nutrients

    University essay from KTH/Maskinkonstruktion (Inst.)

    Author : Karl Lundin; Oscar Olli; [2017]
    Keywords : ;

    Abstract : The purpose of this project is to create a fully automatedgreenhouse that can produce year-round crops, using sensorsand actuators. Temperature in both water and air,relative humidity, water level, nutrient level and pH are allmeasured with different sensors. Though only water level,pH and nutrients will be regulated. READ MORE

  5. 19. Landscape factors related to performance of in-situ sensors for prediction of total phosphorus : a statistical analysis of data from 194 streams in Sweden

    University essay from SLU/Dept. of Aquatic Sciences and Assessment

    Author : Cham Hoang; [2017]
    Keywords : surface water monitoring; surrogate parameters; total Phosphorous; turbidity; catchment; land-use; soil type;

    Abstract : Accurate monitoring data of phosphorus concentrations in the water will benefit the evaluation of measures taken to reduce the problems of eutrophication. Today, the quantification of phosphorus loads from diffuse sources involves large uncertainties. READ MORE

  6. 20. 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
