Design Procedure of a Rectangular Sedimentation Tank
The topic of this tutorial highlights on the design method of a rectangular sedimentation tank which is also called settling tank.
Before we move on straight to the tutorial; we need to know what actually a sedimentation tank is? A sedimentation tank is run by a separation method in which a suspension is separated into two stages - (1) overflow and (2) underflow.
Purpose of Settling
- To eliminate coarse dispersed phase.
- To get rid of coagulated and flocculated impurities.
- To extract precipitated impurities after chemical treatment.
In the design calculation we will provide solution to the following problem.
Design a rectangular sedimentation tank for a population of one lakh people. Rate of water supply is 150 lit/no/day. Water will stay for 2 hours in tank (detention period)
