  1. 21. A Quantitative Microbial Risk Assessment Associated with Cross-Connections in the Drinking Water Network in Combination with Hydraulic Modeling

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Fatin Alzuhairi; [2022]
    Keywords : EPANET; QMRA; Water distribution network; Health risk analysis; Cross-connections and backflow; Low pressure; Water quality; Simulation; Pathogen; EPANET; QMRA; vattendistributionsnät; hälsoriskanalys; korskoppling; lågtryck; vattenkvalitet; simulering; patogen;

    Abstract : Drinking water companies have the technology and responsibility to deliver safe and high-quality drinking water to the water distribution systems network (WDN). However, many events within the WDN, such as cross-connections and backflow, might degrade water quality and pose public health risks to consumers. READ MORE

  3. 22. Analysis of Benzoisothiazolinone in process water from operations that handle large amounts of paint residues

    University essay from KTH/Kemi

    Author : Cagenna Magendran; [2022]
    Keywords : Flocculation; Gas chromatography-mass spectrometry; Isothiazolinones; Paint residues; Stockholm s water and waste; Flockulering; Gaskromatografi-masspektrometri; Isotiazolinoner; Färg rester; Stockholm vatten och avfall.;

    Abstract : I denna studie undersöks isotiazolinoner i avloppsvatten eftersom det finns i alla kommersiella färger. För att avgöra om reningsverken är tillräcklig bra används gaskromatografi-masspektrometri (GC-MS) för att analysera förekomsten av BIT i processvatten som släpps ut i mjövattnet. READ MORE
