Abstract: A fluid treatment system for placement in a flanged pipe fluid conveyance system. The fluid treatment system comprises a flanged ductile iron pipe fitting. The ductile iron pipe fitting comprises: a 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; and a third flanged opening comprising a first cover element. The first cover element has 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. 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 and thus, can be readily nullsplicednull 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 present invention provides an apparatus and method for accomplishing fluid disinfection by passing fluid flow through a uniform array of ultraviolet lamps having cross sections perpendicular to the direction of fluid flow that define channels for the fluid flow. Positioned next to the end of each lamp at the entrance of the fluid flow are triangular shaped delta wings having surfaces inclined at an angle to the direction of fluid flow. The interaction of the fluid flow with each delta wing creates a pair of vortices that rotate in the same direction or in directions opposed to each other. The counter-rotating vortices reinforce each other to minimize dissipation of their mixing strength as they move down the channel. Due to these co-reinforcing properties these counter-rotating vortices more promote efficient mixing of the fluid which is required to achieve more efficient use of the light in the UV disinfection systems, along with heat and/or mass transfer in chemical reactions. Although the present invention is described in particularity as embodied in a UV reactor system, it will be understood by those skilled in the art that the present invention has equal applicability to other types of arrayed flow systems in which increased fluid mixing is desired.

Abstract: A mass transfer system for decontaminating a contaminated liquid or gas stream. The system includes a container with a liquid inlet, a liquid outlet, a gas inlet and a gas outlet. The container is adapted to channel a liquid stream from the liquid inlet to the liquid outlet. The vessel is also adapted to channel a gas stream from the gas inlet to the gas outlet. At least one grid is mounted within the container and is positioned within the gas and liquid streams. The grid has a plurality of apertures formed therein which are adapted to disperse the gas flow as it passes through the grid. The dispersion of the gas flow generates a fluidized bed within the container. The grid is preferably parabolic in shape. A light assembly is mounted on the container and has a light emitting unit positioned so as to emit light into the container. The light irradiates at least one of the streams flowing therein. The configuration of the system is designed to cause the mixture of the gas stream and liquid streams to become turbulent, thereby increasing the liquid surface area. The light emitting unit is positioned so as to irradiate the two turbulent fluid flows so as to catalyze a chemical reaction. In one embodiment, an oxidant is added to one of the streams which, when irradiated by the ultraviolet light, produces hydroxyl radicals which chemically react with the contaminants in the stream.

The EMR source is preferably adapted to emit EMR at a wavelength sufficient to cause photolytic fission of the selected molecules in the fluid, and more preferably adapted to emit EMR at a wavelength sufficient to cause photolytic fission of nitrogen trichloride, diatomic chlorine, or both. Also, an air purging device is optionally provided near the valve so that fluid may be purged from the vicinity of the first optical member when the valve is being closed. Additional optical members, such as a filter, may be optionally disposed between the first optical member and the EMR source.

Abstract: A replaceable wiper cartridge is described which is held captive within a shuttling scraper of a type known in the art which is pushed axially through a cylindrical reaction chamber intermittently to remove reaction products from the inside surface of the reaction chamber and from the outside surface of a smaller coaxial tube that extends the length of the reaction chamber. The replaceable wiper cartridge has an annular shape that is obliquely cut to permit a slight radial expansion to accommodate the smaller coaxial tube and to engage it in a tight sliding grip so as to scrape from the smaller tube any deposits.
