Self-cleaning of networks: the flush valve



Control the accumulation of deposits in the sewerage network to maintain the evacuation capacity, facilitate operation and minimise the risks of malfunctions such as spills, pollution, floods, etc...

The 3D EAU solution

Carry out a diagnostic study of solid transport in order to understand the origin of the deposits and the conditions necessary for their resuspension.

When this solution seems relevant, re-suspend the settled matter using regular flushing in order to minimise deposits and therefore the cleaning operations by directing the deposits to specific extraction points.
