Our duty is to conserve the biological quality of rainwater!


The interceptor traps suspended matter contained in runoff water by gravity.

 The consequences of particle contamination


Unsightly waste and deposits, silting that may affect circulation by provoking flooding.

Possible blocking of the airways of fish, leading to their disappearance from the waterways.

Increasingly turbid water, affecting photosynthesis.

 Operating principle



The Settle Solids Interceptor is defined by its Flow Rate in litres per second and its Hydraulic Head: metres per hour.

The settle solids interceptor is designed to trap particles with a density of 2.4 and a diameter blow of 100 microns, which represents about 80% of the solid particles contained in runoff!


The performances of a settle solids interceptor may be shown as follows   ------------------>


 Two types of decantation



 Static decantation

Requires a decantation tank with an extremely large surface, and a settling rate that is usually low.

 lamellar decantation

Works on the trajectory to separate out continuously particles of different size and mass.
This method improvesthe settling rate considerably, meaning that the settling volume may be reduced.


 Laminar movement is obligatory



For particles to settle effectively, the movement of the water through the interceptor has to be laminar.
All turbulent flow (used in oil interceptors) is therefore to be prevented!

The laminar movement is regular, fluid and rectilinear


Turbulent movement is "disordered" vortex flow.




The oil interceptor, with its coalescing filter, is not suitable for particle settling.
