  1. 1. Fluoride removal by low-cost adsorbents

    University essay from Örebro universitet/Institutionen för naturvetenskap och teknik

    Author : Fredrik Bernheim; [2022]
    Keywords : Fluoride; calcium; adsorption; surface precipitation; pH; AOD-slag; ion chromatography; MP-AES; isotherms; Langmuir; Freundlich; Sips.;

    Abstract : Fluoride, the most abundant form of fluorine, is an ion released into the environment, mainly via anthropogenic sources and erosion of mineral rocks. Although the element is well known for its health benefits on teeth and bones, it can as well be a harmful pollutant. READ MORE

  3. 2. Adsorption of Zn, Cd, V, Ba, Cu, Mo, Ni, Cr, Li and Pb to silicon and aluminium reduced AOD-slag

    University essay from Örebro universitet/Institutionen för naturvetenskap och teknik

    Author : Edvin Elmroth; [2018]
    Keywords : Steel slag; AOD; Si- and Al-reduced slag; Metal adsorption;

    Abstract : During production of steel, slag is formed as a by-product. The process of steelmaking involves usage of additives such as chromium or vanadium as reactants to optimize and produce high quality steel. Vast amounts of slag are formed and there is a continuous search for applications that can make good use of the slag. READ MORE

    Keywords : Waste; Metallurgical Process; Briquetting; Drop Test; Sulphide Capacity;

    Abstract : Paper and pulp industry and steel industry are two major industries in Sweden, both of which are facing big challenges to treat their waste products properly. In this thesis work, initial evaluation of mechanical properties of briquettes made of waste products was performed. READ MORE

  5. 4. Inhibition of phosphorus release from sediments of Lake Erhai through argon oxygen decarburisation slag (AOD) and electric arc furnace slag (EAF) capping.

    University essay from KTH/Mark- och vattenteknik

    Author : Linda Lindholm; [2016]
    Keywords : ;

    Abstract : The effects of eutrophication in lakes and the open seas has been largely the result of phosphorus (P) that accumulate in the sediment. Eutrophication occurs mainly in the waters in densely populated coastal areas and agricultural dominated areas and occurs when an excess of nutrients reach the soil and water. READ MORE

  6. 5. Acid neutralization using steel slags : Adsorption of fluorides in solutions using AOD slags

    University essay from KTH/Materialvetenskap

    Author : Jesper Larsson; [2015]
    Keywords : acid neutralization; AOD slag; fluoride adsorption; syraneutralisering; AOD slagg; fluoradsorption;

    Abstract : Surface treatment processes of stainless steel, such as pickling, produces acidic waste water consisting of Na⁺, Cl⁻, F⁻, NO⁻3, SO42-, PO43-, Fe3+, Cr6+ and Ni2+. At Sandvik ABs steel works in Sandviken, this waste water is treated and neutralized using slaked lime before being released into the lake Storsjön. READ MORE
