How can I measure the thickness of a sedimentation layer in a closed tank?

WebSettling tanks are divided into two main categories: primary and secondary (final) sedimentation tanks. It is worth making a distinction between these types of tank. Primary sedimentation tanks are designed to reduce the particulate flow velocity and provide for the settling of organic solids (AWWA, 1990). The sludge in these tanks is WebNot all systems use pre-sedimentation, but pre-sedimentation is often used when raw water turbidity is high or highly variable. Pre-sedimentation basins range in size, depending on the flow, and the water is sometimes pre-treated with a coagulant and/or a polymer prior to entering the pre-sedimentation basin (AWWA, 1999).
