A gravity thickener would include which of the following components?

• A. Belt Press
• B. Freeze-Thawing Beds
• C. Cartridges
• D. Vacuum Filtration

Answer: (B)

Gravity thickening relies on solids settling out of the liquid under the influence of gravity, so the equipment involved is designed for passive separation rather than mechanical dewatering or filtration. Belt presses, cartridge filters, and vacuum filtration are all methods that remove water through mechanical means or filtration, not by gravity alone. A freeze-thawing bed, on the other hand, is a type of settling bed that promotes concentration of solids through gravity as water drains away and the sludge settles, making it consistent with gravity-based thickening. Therefore, freeze-thawing beds are the component associated with a gravity thickener.
