Pumping off the collecting gravel wash water to the separation system
Kieswerk Hess AG, Laupen, Switzerland
The submersible pumps that were previously used transported the gravel wash water to the separation system in a way that interfered with the efficiency of the plant.
Use of type KRS822 submersible wastewater pumps that are tested for continuous operation and that can be controlled using an intake quantity regulator that is independent of rpms.
The result is a more highly efficient plant. The amount of sediment in the basin decreases as a result of the constant movement of water. Pressure and air surges in the pipelines are avoided.
