    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Arkitektur och vatten

    Författare :Per-Albin Norman; [2018]
    Nyckelord :Stormwater; Treatment; Metals; Sorbents; Batch equilibrium test; Isotherms; Kinetic test; Catch basin inserts;

    Sammanfattning : Urban stormwater is today recognized as a significant source of pollution that has contributed to the deterioration of water quality in lakes and streams. Of the pollutants, metals are commonly occurring in stormwater and can cause major damage when released into the receiving waters. LÄS MER

  2. 2. Remediation of Contaminated Groundwater Using a SpinChem® Rotating Bed Reactor : Competitive Sorption of Metal(loid)s in Complex Solutions under Varying Geochemical Conditions

    Master-uppsats, Luleå tekniska universitet/Geovetenskap och miljöteknik

    Författare :Pär Alapää; [2018]
    Nyckelord :Groundwater Remediation; Competitive Sorption; SpinChem;

    Sammanfattning : The potential of utilizing a new form of chemical processing technology called SpinChem® Rotating Bed Reactor (RBR), in combination with different reactive materials, for the purpose of remediating multi-contaminated aquifers under changing environmental conditions, was investigated using laboratory studies and geochemical models. Four different reactive materials, or combinations thereof, were tested: heat-treated peat powder combined with zero-valent iron (ZVI); IronPeat, which consists of peat powder coated with a ferriferous hydrosol (FFH); and a powdered steel waste product.

  3. 3. Termisk energilagring i fjärrvärmenät

    Master-uppsats, KTH/Energiteknik

    Författare :Julia Kuylenstierna; [2018]
    Nyckelord :;

    Sammanfattning : District heating is the most common form of heating in Sweden and as other industries it faces challenges in terms of increased resource utilization and transition to 100% renewable energy sources. Thermal energy storage in district heating networks can bring several advantages, for example enabling the use of excess energy, reduction of equipment size and capacity, as well as load leveling.

  4. 4. Arsenic (V) and Phosphate sorption to Swedish clay soils - Freundlich sorption modelling.

    Master-uppsats, KTH/Miljögeokemi och ekoteknik

    Författare :Luhuvilo Mwamila; [2011]
    Nyckelord :Freundlich modeling; Arsenic V ; Phosphate; Adsorption; Swedish clay soil;

    Sammanfattning : This thesis is an attempt to analyze and interpret the behavior of the two elements arsenic and phosphorus when released into the environment. Both of them may occur naturally in the environment but also may be added to the environment for certain purposes e.g. as pesticides and fertilizers respectively or through anthropogenic sources.
