Trapping sands: Bed load trap
Trapping and storing only the solid elements transported with the effluents in order to avoid the inconveniences caused by the accumulation of organic matter and grease in a traditional grit chamber.
Typical inconveniences of a grit chamber: grease retention, H2S generation, resuspension of trapped particles
A more compact and better-performing solution compared to traditional grit chambers.
The 3D EAU solution
Trapping of mineral matter using a calibrated opening to minimise resuspension while avoiding the accumulation of grease and floating debris in the trap.
Prevents the accumulation of organic matter, grease and floating debris.
Optimises the size and cost of the storage facility with better flow management.
Prevents the re-suspension of stored solids.

Step 1 - Feasibility study
Taking into account the actual hydraulic environment of the upstream network.
Characterisation of the hydrodynamics and solid transport in the network, good integration of the equipment in the existing environment.
Possible optimisation of an existing grit chamber by fitting a transit channel to it.
Step 2 - Design and implementation
Design, manufacture and assembly in the workshop
Step 3 - Delivery
Assistance with commissioning
Prevent the floatation of grease and the accumulation of floating debris
Guarantees the trapping and storage of solid particles without resuspension
Limits operational constraints
Optimises the cost
