  1. 1. Spillvärmeåtervinning på Gotland : En analys av potentiella spillvärmesamarbeten ur ett sociotekniskt perspektiv

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Byggteknik och byggd miljö

    Författare :Fredrik Munters; [2023]
    Nyckelord :Spillvärme; Gotland; Got Heat; restvärme; värmeåtervinning;

    Sammanfattning : In this master’s degree thesis potential utilization of excess heat on Gotland is investigated. The report first identifies potential sources and users of excess heat and creates seasonal heat profiles for a few of them. LÄS MER

  3. 2. THE ROLE OF WATER PURITY IN EMULSIFICATION AND REMOVAL OF OIL FROM SOLID SURFACES

    Master-uppsats, Malmö universitet/Institutionen för biomedicinsk vetenskap (BMV)

    Författare :Andriani Tsompou; [2021]
    Nyckelord :ultra-pure water; detergency; detachment of oil from solid surfaces; washing; cleaning;

    Sammanfattning : Detergents are broadly used in our everyday life for cleaning and washing procedures. They are however, a source of water pollution and can have a negative effect on human health and the environment. To reduce their negative impact, a new trend of using only pure water for washing and cleaning applications is being implemented. LÄS MER

  4. 3. Methods for verification of ultra-pure water with air gap membrane distillation : Focusing on applications in the semiconductor industry

    Master-uppsats, Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

    Författare :Pedram Pirouzfar; [2020]
    Nyckelord :;

    Sammanfattning : In the semiconductor industry, the purification process of the silicon wafers is of a great importance. If water of sufficient quality is not used, the silicon wafer surface runs a risk of being destroyed by particles and bacteria sticking to its surface. LÄS MER
