Definitions

  • the present invention relates to a radiation source assembly. In another of its aspects, the present invention relates to a radiation source module comprising a novel radiation source assembly having incorporated therein an optical radiation sensor.
  • Optical radiation sensors are known and find widespread use in a number of applications.
  • One of the principal applications of optical radiation sensors is in the field of ultraviolet radiation fluid disinfection systems.
  • UV700 and UV8000 employ this principle to disinfect water for human consumption.
  • water to be disinfected passes through a pressurized stainless steel cylinder which is flooded with ultraviolet radiation.
  • Large scale municipal waste water treatment equipment such as that commercially available from Trojan Technologies Inc. under the trade-names UV3000 and UV4000, employ the same principal to disinfect waste water.
  • the practical applications of these treatment systems relates to submersion of treatment module or system in an open channel wherein the wastewater is exposed to radiation as it flows past the lamps.
  • passive sensor devices It is known in the art to monitor the ultraviolet radiation level by deploying one or more passive sensor devices near the operating lamps in specific locations and orientations which are remote from the operating lamps. These passive sensor devices may be photodiodes, photoresistors or other devices that respond to the impingent of the particular radiation wavelength or range of radiation wavelengths of interest by producing a repeatable signal level (in volts or amperes) on output leads.
  • the present invention provides a radiation source module for use of fluid treatment system, the module comprising: a frame having a first support member; at least one radiation source assembly extending from and in engagement (preferably sealing engagement) with a first support member, the at least one radiation source assembly comprising at least one radiation source disposed within a protective sleeve; and an optical radiation sensor disposed within the protective sleeve.
  • the present invention provides a radiation source assembly for use in a radiation source module, the radiation source assembly comprising at least one radiation source and an optical radiation sensor, both the at least one radiation source and the optical radiation sensor being disposed within a protective sleeve.
  • the present invention provides a fluid treatment system comprising: a fluid treatment zone; at least one radiation source assembly disposed in the fluid treatment zone, the at least one radiation source assembly comprising at least one radiation source disposed within a protective sleeve; and an optical radiation sensor disposed within the protective sleeve.
  • the fluid treatment zone comprises a housing through which fluid flows.
  • the at least one radiation source assembly is secured to the housing.
  • the cleaning system serves the purpose of removing fouling materials from the protective sleeve to allow for optimum dosing of radiation, a separate cleaning system for the sensor is not required.
  • the optical radiation sensor is disposed within an existing element (the protective sleeve) of the radiation source module, incorporation of the sensor in the module does not result in any additional hydraulic head loss and/or does not create a "catch" for fouling materials.
  • Figure 1 is a side elevation of an embodiment of the present radiation source module
  • Figure 2 is a sectional view of a trio of radiation source modules including the radiation source module illustrated in Figure 1 ;
  • Figure 3 illustrates an enlarged sectional view taken along line A-A in Figure 2.
  • a radiation source module 100 is illustrated.
  • Radiation source module 100 comprises a pair of support legs 105,110 depending from a crosspiece 115. Disposed between support legs 105,110 are a trio of radiation source assemblies 120,125,130. Each radiation source assembly
  • each protective sleeve 145 is connected to support leg 105 via a coupling nut 150.
  • the details of this connection are preferably as set out in copending United States patent application S.N. 09/258,142 (Traubenberg et al.).
  • radiation source assembly 125 comprises an optical radiation sensor 150 disposed within protective sleeve 145 adjacent support leg 110.
  • Optical sensor 150 comprises a window 155(optional) which receives incident radiation and passes this radiation into a body 160 that contains a photodiode (not shown) or other radiation sensor material as described above. A signal related to the amount of radiation sensed is then sent from body 160 through a lead 165 which is connected to a conventional control system which allows the user to ascertain the level of radiation sensed compared to a predetermined benchmark.
  • sensor 160 is oriented within protective sleeve 145 in a manner that it receives incident radiation from at least one, preferably both, of adjacent radiation source assemblies 120,130. In other words, it is preferred that sensor 150 not receive incident radiation from the radiation source contained within the same protective sleeve in which sensor 150 is housed.
  • the sensor itself may be chosen from conventional sensors.
  • a suitable sensor is commercially available from UDT Sensors Inc. (Hawthorne, California).
  • radiation source module 100 may be a member of an array of radiation source modules which do not contain an optical radiation source sensor.
  • the trio of radiation source modules illustrated in Figure 2 could be placed in an open channel as shown in United States Patents 4,872,980 and 5,006,244 and used to treat wastewater as set out in those patents.
  • the present invention has been illustrated with reference to radiation source modules similar in general design to those taught in United States Patents 4,872,980 and 5,006,244, it is possible to employ the present radiation source assembly in a module such as the one illustrated in United States Patents 5,418,370 , 5,539,210 and 5,590,390 - i.e., in a module having a single support for one or more elongate source assemblies extending therefrom. Further, it is possible to employ the present radiation source assembly in a fluid treatment device such as those commercially available from Trojan Technologies Inc. under the tradenames UV700 and UV8000.
  • the optical sensor is disposed at the end of the projective sleeve opposite the end where electrical connections for the lamp are located, it possible to locate the optical radiation sensor at the same end as the electrical connections for the lamp thereby allowing for use of the protective sleeve having one closed end. Still further, it is possible to utilize an optical radiation source sensor disposed between two radiation sources, all of which are disposed within a protective sleeve.
