Solids that settle in a sedimentation basin are called ___.

Explanation:
In a sedimentation basin, the settled solids form sludge. Gravity settling concentrates suspended solids into a dense, semi-solid layer that collects at the bottom; this material is called sludge and is periodically removed for further treatment or disposal. Other terms aren’t used here in practice: sediment is a more general term for any deposited material, slurry describes a mixture of solids in liquid, and dregs is an older or less specific word. So the bottom, clarified solids collected from this process are referred to as sludge.
