A » Primary sedimentation involves the removal of readily settleable solids from wastewater, typically occurring in a primary clarifier. Secondary sedimentation follows biological treatment, focusing on separating biological flocs or sludge from treated water in a secondary clarifier. Both processes are essential for reducing suspended solids and improving water quality in wastewater treatment facilities.

A »Primary sedimentation removes suspended solids and organic matter through physical settling, while secondary sedimentation follows biological treatment, removing remaining suspended solids and biomass. The key difference lies in the treatment stage and the type of solids being removed.
