Self-cleaning of networks: the flush gate
Issue
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.
Strong points
-
Allowing self-cleaning of the network and facilitating the extraction of sands
-
Optimises maintenance costs

General methodology
Step 1 - Feasibility study
​
Taking into account the actual hydraulic environment of the network
Characterisation of the hydrodynamics and solid transport in the network, good integration of the equipment in the existing environment
Step 2 - Design and implementation
​
Design, manufacture and assembly in the workshop
​
Physical testing on our hydraulics bench
