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

    Author : Kristjan Pullerits; Teknisk mikrobiologi; []
    Keywords : 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;

    Abstract : 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. READ MORE

  4. 2. Towards Energy-Efficient Drinking Water Production using Biomimicry

    Author : Simon Isaksson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Filter; Membrane Protein; Supported Lipid Bilayer; Drinking Water; Water Treatment; Silica; Aquaporin; Liposome; Biomimicry;

    Abstract : Water is a prerequisite for life and we therefore need pure drinking water to survive. Yet there are more than half a billion people that do not have access to pure drinking water. Water treatment can be performed in many different ways, one of the most commonly used being filtration. READ MORE

  5. 3. Processes governing the drinking water microbiome

    Author : Sandy Chan; Teknisk mikrobiologi; []
    Keywords : Drinking water microbiome; Biofilm; Slow sand filters; Ultrafiltration; Bacterial community; Flow cytometry; Next generation sequencing;

    Abstract : AbstractSafe drinking water is far from sterile and can contain 10^3-10^5 bacteria/mL. This water microbiome can be altered through various treatment processes in the drinking water treatment plant (DWTP), particularity when it comes in contact with biofilms. READ MORE
