1. A device for decontaminating a turbid liquid comprising:
a sheath extending longitudinally along an axis X, comprising an external wall and an internal wall which are substantially coaxial with one another and delimiting an annular circulation space for the liquid that is to be decontaminated,
a source of ultraviolet rays positioned in a central space delimited by the internal wall of the sheath, coaxially with the annular circulation space, characterized in that the external wall comprises a cylindrical surface facing the annular circulation space having a profile along a generatrix of the cylindrical surface comprising an alternating succession of concave and convex shapes,
wherein the profile along the generatrix of the cylindrical surface comprises a succession of asymmetrical waves,
wherein each wave of the succession of waves comprises a hollow forming the concave shape and a peak forming the convex shape,
wherein a hollow of a first wave in the succession of waves is connected to a hollow of an adjacent wave in the succession of waves by a shorter slope, the peak, and then a longer slope.
