Problem C2 Theory

  1. 1. Problem C2Batch Sedimentation<br />Sibug, Anna Kristina L.<br />Tan, Maria Kimberly L.<br />Villanueva, Von Kirby<br />
  2. 2. Sedimentation<br />- is the process wherein a dilute slurry is settled by gravity into a clear fluid and a slurry of higher solids concentration.<br />- the partial separation of concentration of suspended solid particles from a liquid by gravity settling.<br />

  4. 4. Principles/Theories<br />Figure 1. Behaviour of batch curve during batch sedimentation process<br />
  5. 5. Kynch Method<br /> graphical approach that is used to find the settling velocity of a slurry or suspension over time<br /> Restrictions<br />neglecting wall effects <br />assuming uniform particle size and shape<br />the particle reaches zero at large times<br />the system must obey Stokes’ Law<br />
  6. 6. Principles/Theories<br />In the constant settling region,<br />Free settling: settling velocity (ut) is constant<br />In the transition region,<br />Hindered settling region<br />Factors affecting the rate of sedimentation<br />Initial height of the suspension<br />Initial concentration of the suspension<br />Where:<br />Ho= initial height of interface<br />Hc= critical height<br />tc= time in obtaining the critical height<br />
