Since time immemorial, we have used sand and gravel for a very wide range of purposes. Every year, more than 8 billion tonnes of gravel and sand are required and processed in many different places.

During the extraction of sand and gravel, it is often necessary to wash the material. This gives rise to a large volume of polluted water. Using the decanter for cleaning sand washing water and gravel wash water represents an optimum solution.

In the past, the wastewater was often channelled into ponds. There, the fine proportions settled out. This required a lot of space, large volumes of wastewater and took a very long time. Cleaning sand washing water and gravel wash water with the decanter makes these settling ponds superfluous.

The Flottweg decanter guarantees optimum treatment of the gravel wash water and sand washing water. For example, a process water treatment system with a Z92 from Flottweg can process up to 2200 tonnes of sludge daily.
