  2. Decanter centrifuge - Wikipedia

    en.wikipedia.org/wiki/Decanter_Centrifuge

    The rate at which sedimentation occurs is an important characteristic of the decanter centrifuge separation process. The sedimentation rate is influenced by the particle size, the shapes of the particles, their density differential between solid and liquid and the viscosity of the liquid. This process characteristic can be improved by utilizing ...

  3. Lamella clarifier - Wikipedia

    en.wikipedia.org/wiki/Lamella_clarifier

    The surface loading rate (also known as surface overflow rate or surface settling rate) for a lamella clarifier falls between 10 and 25 m/h. For these settling rates, the retention time in the clarifier is low, at around 20 minutes or less, [ 7 ] with operating capacities tending to range from 1–3 m 3 /hour/m 2 (of projected area).

  4. ASTM A53 steel - Wikipedia

    en.wikipedia.org/wiki/ASTM_A53_steel

    Scope of ASTM A53 Standard ASTM A53 is standard specification for pipe, steel, black and hot dipped, zinc-coated, welded and seamless. This specification covers seamless and welded black and hot-dipped galvanized steel pipe in NPS 1⁄8 to NPS 26 [DN 6 to DN 650] (Note 1), inclusive, with nominal wall thickness (Note 2) as given in Table X2.2 ...

  5. Sedimentation coefficient - Wikipedia

    en.wikipedia.org/wiki/Sedimentation_coefficient

    The sedimentation coefficient has units of time, expressed in svedbergs. One svedberg is 10 −13 s. The sedimentation coefficient normalizes the sedimentation rate of a particle to its applied acceleration. The result no longer depends on acceleration, but only on the properties of the particle and the fluid in which it is suspended.

  6. Centrifugation - Wikipedia

    en.wikipedia.org/wiki/Centrifugation

    Molecular properties can be modeled through sedimentation velocity analysis or sedimentation equilibrium analysis. During the run, the particle or molecules will migrate through the test tube at different speeds depending on their physical properties and the properties of the solution, and eventually form a pellet at the bottom of the tube, or ...

  7. Clarifier - Wikipedia

    en.wikipedia.org/wiki/Clarifier

    Economy favors using small tanks; but if flow rate through the tank is too high, most particles will not have sufficient time to settle, and will be carried with the treated water. Considerable attention is focused on reducing water inlet and outlet velocities to minimize turbulence and promote effective settling throughout available tank volume.

  8. Svedberg - Wikipedia

    en.wikipedia.org/wiki/Svedberg

    A laboratory ultracentrifuge. In chemistry, a Svedberg unit or svedberg (symbol S, sometimes Sv [a]) is a non-SI metric unit for sedimentation coefficients.The Svedberg unit offers a measure of a particle's size indirectly based on its sedimentation rate under acceleration (i.e. how fast a particle of given size and shape settles out of suspension). [1]

  9. Sedimentation equilibrium - Wikipedia

    en.wikipedia.org/wiki/Sedimentation_equilibrium

    The advantage of using analytical sedimentation equilibrium analysis for Molecular Weight of proteins and their interacting mixtures is the avoidance of need for derivation of a frictional coefficient, otherwise required for interpretation of dynamic sedimentation. Sedimentation equilibrium can be used to determine molecular mass.
