  1. 6. Sustainable and Safe Use of Non-conventional Waters -Reclaimed Water and Desalinated Water

    Författare :Shuang Liu; Avdelningen för Teknisk vattenresurslära; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Water reuse; Desalination; Strategy; Water security; Guidelines; Policy; Microbial risk assessment;

    Sammanfattning : Fresh water scarcity, pollution and an uneven distribution have caused an increasingly serious global water crisis. One of the most widely adopted response strategies is the exploitation and use of non-conventional water sources. LÄS MER

  3. 7. Impact of Drinking Water Treatment and Pipe Biofilms on Bacterial Dynamics in the Distribution System

    Författare :Kristjan Pullerits; Teknisk mikrobiologi; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Drinking water treatment; Drinking water treatment plant; UV; Slow sand filter; Ultrafiltration; Drinking water distribution system; Biofilm; Biostability; Nitrification; Bacterial communities; Flow cytometry; Next-generation sequencing; 16S rRNA gene amplicon sequencing;

    Sammanfattning : This thesis addresses drinking water quality and microbiology in full-scale drinking water distribution systems (DWDSs). It examines how UV irradiation and slow sand filters (SSFs) alter the water bacteriome, and how the biofilm in the DWDS affects the drinking water quality. LÄS MER

  4. 8. Applications of natural organic matter optical properties for assessing drinking water disinfection and distribution

    Författare :Masoumeh Heibati; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; assimilable organic carbon.; Optical properties; disinfection by-products; drinking water; UV disinfection; dissolved organic matter; distribution network;

    Sammanfattning : The task of providing safe drinking water requires proper monitoring of water quality and treatment performance from source to tap. Accordingly, the demand for online monitoring is increasing both at treatment plants a nd within distribution networks. LÄS MER

  5. 9. Challenges and Opportunities For Safe Water Supply in Mozambique

    Författare :Nelson Matsinhe; Avdelningen för Teknisk vattenresurslära; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; service quality; sustainability.; water treatment; water supply;

    Sammanfattning : In Mozambique, despite considerable investments in the promotion of drinking water supplies, the access to quality water of sufficient quantity for the majority of people is still far from optimal. Current official figures report that nearly half of the country´s population and about 45 per cent of urban residents do not have access to safe water. LÄS MER

  7. 10. Aspects of historical data and health criteria for drinking water network replacement strategies

    Författare :Annika Malm; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; pipe rehabilitation; water distribution network; cost-benefit analysis; Pipe replacement; leakage control; lifetime distribution; pipe failure; health risk; strategic planning; asset management;

    Sammanfattning : The drinking water distribution network represents a major proportion of the investments and capital assets of a water utility. Consequently, qualified insight into future replacement needs provides water utilities with a foundation for financial planning. LÄS MER
