primary flotation process design

Lecture Primary Sedimentation Purpose Sedimentation is a treatment process in which the velocity of the water is lowered below the suspension velocity and the suspended particles settle out of the water due to gravity The process is also known as settling or clarification Settled solids are removed as sludge and floating solids are removed as scum in a clarifier
