  1. 11. Sustainability assessment of urine concentration technologies

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Matilda Gunnarsson; [2021]
    Keywords : Wastewater treatment; urine concentration; alkaline dehydration; nitrification-distillation; ion-exchange; struvite precipitation; MCA; Avloppsvattenrening; urinkoncentrering; alkalisk urintorkning; nitrifikations-destillering; jonbyte; struvitfällning; MKA;

    Abstract : The majority of the nutrients in household wastewater are found in the urine and in order to facilitate the use the nutrients in the urine as fertilizer, the urine can be can be concentrated. To extract the nutrients from the urine, various technologies for urine concentration are being developed today. READ MORE

  3. 12. A Nonlinear Reservoir Model to Simulate Blue-Green Stormwater Systems – An Application to Augustenborg Catchment in Malmö, Sweden

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Emmanuel Ekwu; [2021]
    Keywords : Blue-green stormwater control; Nonlinear reservoir routing model; Stormwater; Modelling; Calibration; Water engineering; Technology and Engineering;

    Abstract : The increasingly rapid urbanization has led to vast impervious surface areas in the urban environment. This situation of impervious surfaces has increased the surface temperature and interrupted the natural water circle, which has negatively impacted the urban environment. READ MORE

  4. 13. Using linear regression and neural network to forecast sewer flow from X-band radar data

    University essay from Uppsala universitet/Institutionen för informationsteknologi

    Author : Fredrik Wigertz; [2021]
    Keywords : Neural network; Linear regression; Flow forecasting; Wastewater; Wastewater treatment plant; Rainfall-runoff modelling; X-band radar; Neurala nätverk; Linjär regression; Flödesprognosering; Avloppsvatten; Reningsverk; Avrinningsmodellering; X-bandradar;

    Abstract : The climate adaptation of our cities and the optimization of our technical systems with regards to weather sets high demands on the availability and the processing of weather data. The possibility to forecast disturbances of influent flow rate to wastewater treatment plants allow control systems counteract these disturbances before they have a harmful effect on the treatment processes.

  5. 14. How can Inflow & Infiltration be effectively and sustainably managed? : MCA as a tool for decision support in planning Inflow & Infiltration

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Erika Qvick; [2021]
    Keywords : Inflow and infiltration; stormwater; sewer system; sustainable urban water management; decision support; multicriteria analysis; Tillskottsvatten; dagvatten; avloppssystem; hållbar urban vattenhantering; beslutsstöd; multikriterieanalys;

    Abstract : Inflow and infiltration (I/I) water in the sewer network originates from groundwater, precipitation, seawater as well as over-leakage from drinking water pipes. It is the proportion of water in the sewer system that is not wastewater and causes problems both at the treatment plant as well as in the sewer network. READ MORE

  6. 15. Design and development of an automated rat trap for sewage system

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Vallabh Venkatachalam; [2021]
    Keywords : Rat trap; automated trap; sewage systems; mechanical rat trap; Råttfälla; automatiserad fälla; avloppssystem; mekanisk råttfälla;

    Abstract : This thesis report describes the design and development of an automated rat trap for sewage system. This rat trap has been designed to have a working duration of 2 months or approximately 15749 hits with trap dimensions length 535 mm, width 430 mm and a height range of 931 – 1151 mm with respect to different sewer pipe diameters.
