The inner cylinder has an outer diameter adapted to form a gap (160) between the outer diameter of the inner cylinder and the inner diameter of the outer cylinder. The media flows in a substantially cyclonic flow path along the gap. The at least one emitter of type C ultraviolet radiation is placed inside the inner cylinder. The outlet is connected to 10 the outer cylinder at, or proximal to, an end of the outer cylinder opposite the inlet.
