Abstract: The device for decontaminating a turbid liquid, in particular of the food type, includes a sheath extending longitudinally along an axis X, including an outer wall and an inner wall substantially coaxial with each other and delimiting an annular circulation space of the liquid to be decontaminated, a source of ultraviolet rays positioned in a central space delimited by the inner wall of the sheath, coaxially with the annular circulation space, the outer wall comprising a cylindrical surface facing the annular circulation space having a profile along a generatrix of the cylindrical surface comprising a succession of concave and convex shapes alternately.
