A town has an existing rectangular settling tank with an effective settling zone of L= 25 m, H =3 m and W =5 m. The settling tank receives a water inflow rate of 0.6 m3/sec. Assume the settling tank behaves like an ideal sedimentation tank, what percentage of removal should be expected for particles with a settling velocity of 0.002 m/sec ? (Overflow rate =Q/A)
