How does a sedimentation tank work?
Thread Content
The settling of particles in the sedimentation tank can be roughly divided into two stages. A short distance below the feed inlet, the particle concentration is very low, and the particles settle essentially freely. At the bottom of the sedimentation tank, the particle concentration gradually increases; the particles settle in a turbulent manner, and their settling velocity is very slow. Therefore, a coagulant is added to the sedimentation tank to accelerate sedimentation. The clear liquid yield of the sedimentation tank depends on its diameter.
Particles in the sedimentation tank can be divided into three layers: the sludge zone, the clear liquid layer, and the intermediate transition zone. I have used some mud interface meters from abroad, and when setting the parameters, it’s generally necessary to pay attention to these aspects
I have a gentle question: does the yield of Qingye depend on the diameter of the sedimentation tank?
Reply to 3# Isabella: The diameter of the sedimentation tank determines the residence time of particles in it, which in turn determines the yield of the clarified liquid.
Reply: 4# liuchao1970 – isn’t it unrelated to height? The residence time should be related to the volume~
