The town of San Joes has an existing horizantal flow sedimentation tank with an overflow rate of 17m3/d.m2 and wishes to remove particles that have settling velocity of 0.1mm/s, 0.2 mm/s and 1 mm/s. What is the percentage removal should be expected for each particle in an ideal sedimentation tanks.

P = 100 (Vs/Vo)

Determine the surface area of a setting tank for the flow rate of 0.5m3/s with a typical overflow rate of 40.3 m3/d.m

Find the tank dimensions

Find the depth? For a detention time of 95 minutes
