Drainage & Sepage Tank
 

Home

The apparatus is designed to demonstrate the hydraulic characteristics and settling efficiencies of a model settling basin. The apparatus consists of a Sedimentation Tank in which the water is fed by overhead tank (available in user laboratory and not in scope of supply) at constant flow rate and is measured with the help of Rotameter. A complete unit for slurry circulation in sedimentation tank also accompanies the set-up including a sump tank for slurry, a feed pump for slurry. Flow rate of slurry entering in sedimentation tank is metered by suitable device.

 

An accurate dye injection system is provided to inject the known volume of dye in the sedimentation tank. In sedimentation tank a weir is fitted which facilitate to enter the well mixed slurry of known concentration in sedimentation tank uniformly.
