  1. 16. Coffee grounds as an adsorbent for heavy metals in water treatment : Study based on the environment around Vattenriket, Kristianstad

    University essay from Linnéuniversitetet/Institutionen för biologi och miljö (BOM)

    Author : Johan Matson; [2020]
    Keywords : Acid sulfate soil; ASS; Adsorption; calcium; coffee residues; exhausted coffee; grounded coffee; pH; total organic carbon; TOC; Vattenriket; Kristianstad; pH; zinc.;

    Abstract : One of the modern times worst environmental problem are polluted water resources. An example of source of pollution to water resources are, heavy metal leached from acid sulfate soils (ASS). READ MORE

  3. 17. Arsenite removal from contaminated water by different sorbent materials

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Kaijie Ding; [2020]
    Keywords : Arsenic contamination; adsorption; hydrotalcite; Mg−Al layered double hydroxide; amorphous aluminium hydroxide; amorphous titanium oxide; adsorption isotherm; co-existing anions;

    Abstract : Arsenic (As) contamination is a worldwide problem, and millions of people are suffering from it. There are two major inorganic forms of As in waters: arsenate(V) and arsenite(III), and adsorption to a sorbent material may be an efficient method to handle them. READ MORE

  4. 18. Modelling adsorption rate in a rotating bed reactor

    University essay from Umeå universitet/Institutionen för fysik

    Author : Jonathan Jonsson; [2018]
    Keywords : computational fluid dynamics; fluid mechanics; cfd;

    Abstract : SpinChem AB designs rotating bed reactors (RBR:s) that are used to conduct reactions between solid and liquid phase. In this work a model have been developed that predicts the performance of the S2 RBR. Coupled with simulations the model could be used to improve current and future RBR designs. READ MORE

  5. 19. Point source carbon capture by porous inorganic carbonates

    University essay from Uppsala universitet/Nanoteknologi och funktionella material

    Author : Jonas Hultberg; [2018]
    Keywords : Carbon capture; Gas separation; Adsorbent; Inorganic carbonates; Point source; Carbon dioxide; Kolavskiljning; Adsorbenter; Oorganiska karbonater; Punktkälla; Koldioxid;

    Abstract : Mesoporous inorganic carbonates (MIC) was synthesized and tested as adsorbents for CO2, using vacuum and temperature swing adsorption. Mesoporous magnesium carbonate (MMC), mesoporous calcium carbonate (MCC) and mesoporous calcium magnesium carbonate (MCMC), all included in MIC, are exceedingly porous with an amorphous structure.

  6. 20. Removal of arsenic from groundwater using adsorption to ferrihydrite-coated laterite in Burkina Faso

    University essay from KTH/Mark- och vattenteknik

    Author : Agnes Hagstroem; [2017]
    Keywords : ;

    Abstract : In several parts of Burkina Faso, there is an urgent need of making arsenic contaminated water potable. The shallow, dug out wells traditionally used in the rural areas provides small, inconsistent yields and are vulnerable to microbes. READ MORE
