Trapping mineral materials: Carriage trap
Issue
Trapping and storing only the solid elements transported with the effluents in order to avoid the inconveniences caused by the accumulation of organic matter, grease and flotsam in a traditional sand chamber.
Nuisances couramment observées dans une chambre à sable, un dessableur ou un piège à cailloux : rétention de graisse, formation d'H2S, remise en suspension des particules piégées
Disposer d'une solution plus compacte et performante que les chambres à sables, les dessableurs et les pièges à cailloux traditionnels en ciblant les particules à piéger.
The 3D EAU solution
Trapping of mineral matter using a calibrated opening to minimise resuspension without promoting grease flotation and float accumulation.
Fights against the accumulation of organic matter, grease and floaters
Optimises the size and cost of the storage facility with better flow management
Prevents the re-suspension of stored solids
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.
Proposed general methodology
Phase 1 - Feasibility study
Taking into account the real hydraulic environment of the 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 sand chamber by adapting a transit channel to it
Phase 2 - Design and implementation
Design, manufacture and assembly in the workshop
Phase 3 - Delivery
Delivery on site
Assistance with commissioning
Advantages
-
Does not promote the flotation of grease and the accumulation of floaters
-
Guarantees the trapping and storage of solid matter without resuspension
-
Limits operating constraints
-
Optimises the amount of work
