Sedimentation Method and Sludge Concentration Sensor

The sedimentation method is the most basic way in sewage treatment. It is a process that uses the density difference between suspended particles in water and water to cause sinking under the action of gravity, achieving solid-liquid separation. Grit Tank in Sedimentation Process The grit tank in the sedimentation process is often used as a pretreatment method to remove inorganic particles that are easy to settle in the water. The grit chamber is a pretreatment unit that uses physical methods to separate sand particles from water. Its function is to separate particulate matter from water with a relative density greater than 1.5 and a particulate size of 0.2mm or more, which mainly includes inorganic sand, gravel, and a small amount of dense organic particles such as core skins, seeds, etc. Grit chambers are generally set up before lifting equipment and treatment equipment to protect water pumps and pipes from wear, prevent subsequent blockade of water structures and reduction of the vol…
