Technical Description
The HM 142 Model Sedimentation Tank is used to depict the deposition of solid matter suspended in a flowing medium. During this process the effects of different aspects, such as flow speed, flow path, etc. are observed. Fresh water, to which a suspension of known concentration of chalk emulsion in water is added, flows through a sedimentation basin made of transparent plastic. Disturbances can be produced in the flow with the aid of a baffle plate. The sediment content at the basin inlet and outlet is determined using two Imhoff sedimentation cones. The amount of sediment deposited in the basin is determined from this difference. A circulating pump and bypass, which feeds part of the suspension pumped back to the tank, ensure that the suspension is always evenly mixed and no sedimentation takes place in the tank. Ink can be added to the flow of fresh water to demonstrate the flow behaviour in the sedimentation basin and the distribution in the flow observed. The experiment is designed as a laboratory unit and is optimally suited to demonstrations and group experiments in the laboratory.
