A sedimentation tank is a structure used to remove large amounts of solid materials from a liquid stream. There are several synonyms for the term sedimentation tank, including sedimentation basin, clarifier, settling tank, and gravity separator. These terms refer to the same type of structure with the same purpose, differing only in their specific use and design. A sedimentation basin is typically used for municipal and industrial wastewater treatment, while a clarifier is commonly found in water treatment plants. Settling tanks are used in a variety of applications, both industrial and environmental, and gravity separators are commonly used in oil and gas processes. Regardless of the specific name used, sedimentation tanks play an important role in the efficient treatment of liquid streams.
