A device for sterilizing water or another fluid, including a flexible bag through which the fluid is pumped and formed of a material transparent to ultraviolet radiation, with the bag extending first along one side of an ultraviolet lamp or lamps and then being doubled back along their opposite sides; and with the bag being pressed against the lamps by the pressure of the fluid being treated in a manner causing an inner wall of the bag to conform approximately to the shape of the lamp or lamps and thereby enhance or optimize the delivery of radiation to the fluid.
