Primary Treatment (Clarification)
Flotation
Dissolved Air Flotation (DAF) separates suspended solids, such as oils and greases, by carrying them to the surface using fine air bubbles, generally after a chemical flocculation step.

Sedimentation
Sedimentation uses gravity to allow particles to settle to the bottom, often serving as a preliminary clarification step before filtration.
