  1. 11. Boiling heat transfer of multiple impinging water jets on a hot rotary cylinder

    University essay from Högskolan i Gävle/Avdelningen för byggnadsteknik, energisystem och miljövetenskap

    Author : Aitor Uriarte; [2021]
    Keywords : Quenching; unsteady heat transfer; multiple impinging jet; boiling; rotary cylinder; fast cooling.;

    Abstract : Quenching technique is widely used in industrial applications as it enhances the mechanical properties of metals such as hardness and tensile strength. This technique consists of a heating process followed by fast cooling which results in different microstructures that enhance the metal behavior. READ MORE

  3. 12. Investigation of sustainable methods to reduce water hardness in drinking water treatment plants

    University essay from Lunds universitet/Miljövetenskaplig utbildning

    Author : Élise Karlsson Faudot; [2021]
    Keywords : Water hardness; sustainability; Bulltofta water treatment plant; water hardness reduction; plant biomass; plastic; pumice stone; adsorption; Earth and Environmental Sciences;

    Abstract : Water hardness is caused by magnesium and calcium ions (Mg2+ and Ca2+), and can result in formation of deposits, destruction of soap and increase of copper corrosion in old plumbing pipes. To soften the originally hard groundwater supplying 20% of Malmö’s drinking water, Bulltofta water treatment plant imports burned lime from Germany. READ MORE
