1. 1. Dephosphorisation of Acidic Wastewater : Aimed to allow the recirculation of byproducts as slag builders

   Kandidat-uppsats, KTH/Skolan för industriell teknik och management (ITM)

   Författare :Henrik Welander; Martin Palm; [2018]
   Nyckelord :Phosphorus removal; Use of Polonite®; Sustainable Metallurgy; Recycling; Neutralization of Wastewater.; Fosforrening; Användning av Polonite®; Hållbar Metallurgi; Återvinning; Neutralisering av Avfallsvatten.;

   Sammanfattning : This study was conducted to evaluate if Polonite® could remove Phosphorus from Sandvik’s wastewater that naturally forms during steelmaking, and hence be proficiently used as a precursor of the neutralization process of said steel plant. Currently lime (CaO) is mixed with the wastewater which creates clean water and sediments, that later need to be landfilled. LÄS MER

3. 2. Neutralizing acidic wastewater from the pickling process using slag from the steelmaking process : A pilot study in project "Neutralsyra"

   Kandidat-uppsats, KTH/Materialvetenskap

   Författare :Julia Brännberg Fogelström; Amelie Lundius; Hedda Pousette; [2017]
   Nyckelord :Slag; Neutralization; Lime; Lime Concentrate; Acidic wastewater; pH; Landfill; Byproducts; Slagg; Neutralisering; Kalk; Kalkkoncentrat; Surt avfallsvatten; pH; Deponi; Restprodukter;

   Sammanfattning : Properties and origins of two byproducts from steelmaking plants, slag and acidic wastewater, are investigated in this report. The slags' suitability as neutralizing agents of acidic wastewater from the pickling process, with regard to amount of slag required and the environmental impact of the produced byproducts is investigated.
