Definitions
- the present invention relates to a fluid treatment system for placement in a flanged pipe fluid conveyance system. In another of its aspects, the present invention relates to a method of installing a fluid treatment system in an existing piped fluid conveyance system.
- Fluid treatment devices and systems are known. For example, United
- the devices and systems described in the '809, '980 and '244 patents generally include several UN lamps, each of which are mounted within sleeves extending between two support arms of the frames.
- the frames are immersed in the fluid to be treated which is then irradiated as required.
- the amount of radiation to which the fluid is exposed is determined by the proximity of the fluid to the lamps.
- One or more UN sensors may be employed to monitor the UN radiation output of the lamps and the fluid level is typically controlled, to some extent, downstream of the treatment device by means of level gates or the like. Since, at higher flow rates, accurate fluid level control is difficult to achieve in gravity fed systems, fluctuations in fluid level are inevitable. Such fluctuations could lead to non-uniform irradiation in the treated fluid.
- the modules comprising the sleeves are usually removed from the channel and immersed in a separate tank containing a suitable cleaning fluid.
- the device In closed systems, the device must be shut down and the sleeves are thereafter cleaned by charging with a suitable cleaning fluid or by removal of the lamps in the manner described for the open, channel-like systems.
- the operator In either type of system, the operator must accept significant downtime of the system and/or invest significant additional capital to have in place sufficient redundant systems with appropriate control systems to divert the flow of fluid from the systems being cleaned.
- the system described in the '896 patent is a significant advance in the art in that it obviates a number of disadvantages deriving from the devices and systems '809, '980 and '244 patents.
- the system described in the '896 patent is ideally suited for use in an open, channel-like system and is not readily adaptable to be used in a completely closed system where the flow of fluid is fed under pressure in a pipe.
- Closed fluid treatment devices are known - see, for example, United States patent 5,504,335 (assigned to the assignee of the present invention).
- the '335 patent teaches a closed fluid treatment device comprising a housing for receiving a flow of fluid.
- the housing comprises 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 fluid inlet, the fluid outlet and the fluid treatment zone are in a collinear relationship with respect to one another.
- the at least one radiation source module comprises a radiation source sealably connected to a leg which is sealably mounted to the housing.
- the radiation source is disposed substantially parallel to the flow of fluid.
- the radiation source module is removable through an aperture provided in the housing intermediate to fluid inlet and the fluid outlet thereby obviating the need to physically remove the device for service of the radiation source.
- WO 01/25154 is another prior art reference which teaches a closed fluid treatment device.
- a closed fluid treatment device comprising a housing for receiving a flow of fluid.
- the housing comprises 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 having a longitudinal axis disposed in the fluid treatment zone substantially transverse to the direction of fluid flow through the housing.
- the fluid inlet, the fluid outlet and the fluid treatment zone are arranged substantially collinearly with respect to one another.
- the fluid inlet comprises an opening characterized by two features. First, the opening has a cross-sectional area less than a cross-sectional area of the fluid treatment zone. Second, the opening has a largest diameter substantially parallel to the longitudinal axis of the radiation source disposed in the fluid treatment zone.
- the present invention provides a fluid treatment system for placement in a flanged pipe fluid conveyance system, the fluid treatment system comprising:
- a flanged ductile iron pipe fitting comprising:
- first flanged opening and a second flanged opening in substantial alignment to define a flow axis aligned substantially parallel to a direction of fluid flow through the first opening and the second opening;
- a third flanged opening comprising a first cover element, the first cover element having connected thereto at least one radiation source assembly comprising at least one elongate radiation source having a longitudinal axis substantially transverse to the flow axis.
- the present invention provides a method of installing a fluid treatment system in an existing piped fluid conveyance system, the method comprising the steps of:
- the flanged pipe ductile iron pipe fitting comprising:
- first flanged opening and a second flanged opening in substantial alignment to define a flow axis aligned substantially parallel to a direction of fluid flow through the first opening and the second opening;
- a third flanged opening comprising a first cover element, the first cover element having connected thereto at least one radiation source assembly comprising at least one elongate radiation source having a longitudinal axis substantially transverse to the flow axis;
- the present invention provides afluid treatment system for placement in a flanged pipe fluid conveyance system, the fluid treatment system comprising:
- a flanged non-metallic pipe fitting comprising:
- first flanged opening and a second flanged opening in substantial alignment to define a flow axis aligned substantially parallel to a direction of fluid flow through the first opening and the second opening;
- a third flanged opening comprising a first cover element, the first cover element having connected thereto at least one radiation source assembly comprising at least one elongate radiation source having a longitudinal axis substantially transverse to the flow axis.
- the present inventors have developed a novel fluid treatment system for placement in a flanged piped fluid conveyance system.
- the present fluid treatment system may be advantageously utilized to treat fluid such as water, e.g., municipal waste water, municipal drinking water and the like.
- the present fluid treatment system is particularly advantageous since it utilizes a standard ductile iron pipe fitting and thus, can be readily "spliced" into existing piping systems, often referred to as a pipe gallery.. This facilitates installation of the system and also allows for a significant lowering of manufacturing costs of the system.
- the present fluid treatment system utilizes a flanged ductile iron pipe fitting in which there is disposed a plurality of radiation source assemblies, each radiation source assembly comprising at least one elongate radiation source having a longitudinal axis substantially transverse to the axis of fluid flow through the flanged ductile iron pipe fitting.
- the flanged pipe fitting is constructed from a standard ductile iron pipe fitting thereby greatly reducing direct manufacturing costs and facilitating installation of the system in an existing fluid conveyance or piping system.
- the flanged ductile iron pipe fitting can take a number of different shapes.
- the flanged pipe fitting can be T-shaped, cruciform-shaped, Y-shaped and the like.
- the longitudinal axis of the radiation source in the fluid treatment system is disposed substantially transverse to the direction flow of fluid through the flanged ductile iron pipe fitting. While the preferred orientation of the radiation source is such that its longitudinal axis is substantially orthogonal to the direction of fluid flow through the flanged ductile iron pipe fitting, it is possible to orient the radiation source such that its longitudinal axis is otherwise angled with respect to the direction of fluid flow through the flanged ductile iron pipe fitting.
- Flanged ductile iron pipe fittings are generally known in the art and typically are available as "off the shelf type products. See the Appendix attached hereto for more information on flanged ductile ' iron pipe fittings commercially available from U.S. Pipe.
