Abstract: It is often desirable to operate ultraviolet (UV) water treatment systems at high fluid velocities; such as, when low UV doses are required, the UV transmittance of the water being treated is high, or when a high intensity radiation source is used. The operation of an open channel UV fluid treatment system at high fluid velocity causes a disproportionate amount of water to pass through the relatively low intensity region above the top lamp. This results in non-uniform UV dose delivery and poor reactor performance. In one embodiment of the invention, by elevating the inlet to the irradiation zone of the fluid treatment system with respect to the outlet, the amount of water that passes above the top lamp can be minimized, improving overall system performance. The means of elevation can consist of a step or slope in the channel, or a combination of both. Depending on the magnitude of elevation, an increase in maximum velocity of approximately two times can be obtained. In practice, a means must be provided to prevent damage to the radiation sources of the elevated banks that become exposed during periods of low flow. This can consist of either a mechanism for switching off the affected lamp when low water level or high temperature is detected, or a means of lamp cooling.

Abstract: A fluid treatment device comprising a housing for receiving a flow of fluid, the housing comprising a fluid inlet, a fluid outlet, a fluid treatment zone disposed between the fluid inlet and the fluid outlet, and at least one radiation source module disposed in the fluid treatment zone, the at least one radiation source module comprising a radiation source sealably connected to a leg, the leg sealably mounted to the housing, the radiation source being disposed substantially parallel to the flow of fluid. A method of treating a fluid in a housing comprising a fluid inlet, a fluid outlet, a fluid treatment zone disposed between the fluid inlet and the fluid outlet, the fluid treatment zone having at least one radiation source disposed therein is also described. The method comprises the steps of: (i) providing a flow of the fluid to the fluid inlet; (ii) feeding the flow of fluid from the fluid inlet to the fluid treatment zone in a manner substantially parallel to the at least one radiation source; (iii) irradiating the flow of fluid in the fluid treatment zone; and (iv) feeding the flow of fluid to the fluid outlet. During the method, the flow of fluid through the fluid inlet, the fluid outlet and the fluid treatment zone is substantially collinear. The fluid treatment device and method are ideally suited (but not limited) to inactivate microorganisms present in water.

Abstract: A novel ultraviolet fluid purification or sterilization device (1) is disclosed. Lamp sections (2) each composed of opposed pairs of fluid impermeable light unit receiving sockets (7) and lamp units (3) therebetween each consisting of an inner, elongate, cylindrical ultraviolet ray emitting lamp (4) and an outer, coaxial and substantially co-extensive cylindrical sleeve (5), are arranged in parallel rows. Due to its immersion capability, the array of rows of lamps can be fluid immersed in either an open or closed system. Moreover, lamp withdrawal fluid impermeable closure means (21,22,23) is provided on at least one of each pair of sockets (7) to facilitate lamp withdrawal in the event of burnout. Each row of lamps (4) can also be modularized to facilitate easy removal of a malfunctioning row of lamps without having to shut down or remove the entire device from its fluid environment.
