Abstract: A fluid treatment system (100) for placement in a flanged pipe fluid conveyance system. The fluid treatment system (100) comprises a flanged ductile iron pipe fitting (105). The ductile iron pipe fitting (105) comprises: a first flanged opening (110) and a second flanged opening (120) in substantial alignment to define a flow axis aligned substantially parallel to a direction of fluid flow (A) through the first opening (110) and the second opening (120); and a third flanged opening (130) comprising a first cover element (155). The first cover element (155) has connected thereto at least one radiation source (150) assembly comprising at least one elongate radiation source having a longitudinal axis substantially transverse to the flow axis. In its preferred form, the 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 fluid treatment system is particularly advantageous since it utilizes a standard ductile iron pipe fitting (105) and thus, can be readily "spliced" into existing piping systems. This facilitates installation of the system and also allows for a significant lowering of manufacturing costs of the system.

Abstract: The is described a process for determining a validated Reduction Equivalent Dose for reducing the concentration of a target contaminant contained in a fluid in a radiation fluid treatment system. In one embodiment, the process comprises the steps of: (a) determining a short wavelength Reduction Equivalent Dose for the target contaminant or a challenge contaminant in a first region of the electromagnetic spectrum having a wavelength of less than or equal to about 240 nm; (b) determining a long wavelength Reduction Equivalent Dose for the target contaminant or a challenge contaminant in a second region of the electromagnetic spectrum having a wavelength of greater than about 240 nm; and (c) summing the short wavelength Reduction Equivalent Dose and the long wavelength Reduction Equivalent Dose to produce the validated Reduction Equivalent Dose for the target contaminant. In a preferred embodiment, the present invention provides a useful approach for determining the relevant Reduction Equivalent Dose (RED) for Cryptosporidium disinfection and accomplishes this by using the discovered relation between the short wavelength sensor signal and the short wavelength RED, and subtracting the short wavelength RED from the RED determined using a challenge microbe with synthetic lamp sleeves, to obtain the long wavelength RED applicable to Cryptosporidium disinfection. In a bioassay, one would only need the short wavelength sensor reading and the challenge microbe RED using synthetic lamp sleeves to determine the applicable RED, once the relationship between the short wavelength sensor reading and the short wavelength RED was established.
