Ideal Sedimentation Design Assumptions
(a) Homogeneous inlet zone (same particle size distribution at all depths).
(b) Discrete particle (Type I) settling.
(c) Uniform horizontal flow within sedimentation zone.
(d) Outlet zone to transfer uniform flow to discharge flow.
(e) The particles are not re-suspended from sludge zone.
(f) All particles along with settling velocity greater than the critical velocity (vsc) settle to the sludge zone.
