Flow through period should be less than the the detention time so that the particles can settle down. If it is greater than the detention time then particles won't get a chance to settle down.

Flowing through period is the time taken by a batch of water to travel from the entry to exit of settling tank. Because of short circuits produced in water current, flowing through period is less than the detention period.

Settling time or flow through time should be less than or equal to detention time for 100% removal efficiency.

What is the ideal value of displacement efficiency? is it 1?

Displacement efficiency = (flow through period/theoretical detention time )*100.
Flow through period Decreases theoretical detention time increases.
Flow through period Decreases theoretical detention time increases.

Settling velocity must be more than overflow velocity.

Flow through period is always less than the detention time due to short circuiting.
