Thickening is defined as removal of water from sludge to achieve a reduction in moisture content of slurries. The resulting material is still fluid. Thickening is used at most wastewater treatment plants, as an economic measure, to reduce the volume of sludge or for greater efficiency in subsequent processes.

Gravity separation - Wikipedia

Gravity separation is an industrial method of separating two components, either a suspension, or dry granular mixture where separating the components with gravity is sufficiently practical: i.e. the components of the mixture have different specific weight. All of the gravitational methods are common in the sense that they all use gravity as the dominant force.
