  2. 2. Acoustic separation of submicron particles in gaseous flows

    Author : Ramin Imani Jajarmi; Laszlo Fuchs; Etienne Robert; Klas Engvall; Martin Wiklund; KTH; []
    Keywords : Acoustic; submicron particles; gaseous flows; separation; Engineering Mechanics; Teknisk mekanik;

    Abstract : The separation of submicron particles suspended in gaseous flows is a problem of great importance and is the subject of sustained research efforts. This is motivated by several challenges presented by modern science and technology requiring high separation efficiencies for submicron particles.

  3. 3. Effects of Flow Structure on Particle Separation in Dissolved Air Flotation

    Author : Måns Lundh; Institutioner vid LTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; plasma; Environmental technology; pollution control; Miljöteknik; kontroll av utsläpp; Gases; fluid dynamics; plasmas; Gaser; fluiddynamik; Teknik; Technological sciences; modelling; retention time distribution; acoustic doppler velocimeter; flow structure; separation; water treatment; wastewater treatment;

    Abstract : Dissolved Air Flotation (DAF) is a separation process in water and wastewater treatment. The removal function is based on reducing the density of the particle by producing aggregates of the particles and added micro-bubbles of air, thus lifting the aggregates to the water surface, where they can be removed as sludge.

  4. 4. Acoustic separation and electrostatic sampling of submicron particles suspended in air

    Author : Ramin Imani Jajarmi; Etienne Robert; Lisa Prahl Wittberg; Laszlo Fuchs; Martin Wiklund; Klas Engvall; Jeremy Hawkes; Michel Cervantes; Mats Åbom; Olga Roditcheva; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Acoustic; separation; acoustophoresis; Engineering Mechanics; Teknisk mekanik;

    Abstract : We investigate experimentally the effects of acoustic forces on submicron aerosol in a channel flow. This technique can potentially overcome some of the limitations of conventional separation systems and provide advanced manipulation capabilities such as sorting according to size or density.

  5. 5. Wet Low-Intensity Magnetic Separation: Measurement methods and Modelling

    Author : Jan Stener; Luleå tekniska universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mineralteknik; Mineral Processing;

    Abstract : In the mining industry, ferromagnetic particles (e.g. magnetite) are concentrated using wet low-intensity magnetic separation (LIMS). Mineral particles in suspension with water are pumped into the separator tank, and a magnetic concentrate is extracted by use of magnetic forces. READ MORE
