WebExamples. Water Potabilization: is based on Stokes law and seeks to increase water particles by flotation. Wastewater treatment: the solid matter is removed from the water by means of this process. Sand trap: a type of artificial sedimentation. Alluvium: solid materials are transported and deposited by means of water currents. Webmatter is settled in the primary sedimentation tank (PST). Due to involvement of many unknown parameters under settling of light weight, sticky, and non regular shaped particles, the classical laws of sedimentation such as that applicable in grit removal are not applicable and this settling is called as flocculnt settling. rockford rewind
