International Classification:

G01N 2133

US Classification:

250435

Abstract:

The invention provides an immersible and portable module for irradiating fluids including a multiplicity of ultraviolet radiation producing lamp and a first header for receiving and maintaining in position the multiplicity of ultraviolet radiation-producing lamps, the first header having upstream and downstream ends and opposed sides. There is also a second header for receiving and maintaining in position the multiplicity of ultraviolet radiation-producing lamps, the second header having upstream and downstream ends and opposed sides. Fluid flow diverters are positioned between the first and second headers and located adjacent the opposed sides and are adapted to divert fluids flowing adjacent the opposed sides toward at least some of the ultraviolet radiation-producing lamps.

Abstract:

A method for photochemical reactor characterization includes an application of using dyed microspheres exposed to UV irradiation under a collimated-beam system. Particle specific fluorescence intensity measurements are conducted using samples form the collimated beam and flow-through reactor results using flow cytometry. A numerical model may be used to simulate the behavior of the reactor system to provide a particle-tracking algorithm to interrogate the flow and intensity field simulations for purposes of developing a particle specific estimate of the dose delivery. A method for measuring UV dose distribution delivery in photochemical reactors is provided that includes introducing microspheres labeled with a photochemically-active compound in a UV reactor, The labeled microspheres are harvested downstream of the irradiated zone of a UV reactor and exposed to UV irradiation under a collimated beam of UV irradiation. The method further includes quantifying a UV dose-response behavior, conducting fluorescence intensity measurement on the labeled microspheres from the UV reactor, and developing an estimate of a dose distribution delivered by a UV reactor based on the numerical deconvolution of the sum of the UV dose response behavior and fluorescent intensity of exposed microspheres.
