<emphasis role="bold">SEDIMENTATION</emphasis>
<emphasis role="bold">SEDIMENTATION</emphasis>Sedimentation, clarification, settling, and thickening depending are terms used to describe gravity separation of wastewater solids from liquids depending on whether the focus is clarified liquid or thickened solids (Rich, 1961). Sedimentation and clarification are used interchangeably along with terms such as sedimentation tank, settling tank, clarifier, and settler. Gravity separation removes more suspended solids and COD or BOD at less operational cost than any other method. Clarifiers (sedimentation tanks) equalize raw wastewater quality and flow to a limited degree, thereby protecting downstream unit processes.
