What term describes solids that settle at the bottom of a wet well?

Explanation:
Settleables are solids in wastewater that can settle to the bottom under gravity when the water is still. In a wet well, heavier particles drop out and accumulate as sludge, which is why this term is used to describe what collects at the bottom. Colloidal particles are very small and tend to stay dispersed unless treated; suspended solids remain in suspension and do not settle readily; “scrum” isn’t a technical term in this context. So the best term for solids that settle out at the bottom is settleables.
