Abstract:
Some demonstrative embodiments of the invention may include a liquid disinfection system having built-in cleaning and deposit prevention capabilities. The system may include a conduit to carry a flowing liquid to be disinfected, an illumination source and an ultrasonic cleaning unit mounted on an external surface of the conduit.
Abstract:
There is described a fluid treatment system. The fluid treatment system comprises: an open channel for receiving a flow of fluid and a fluid treatment zone. The fluid treatment zone comprising a plurality of elongate radiation source assemblies orientated such that: (i) a longitudinal axis of each radiation source assembly is transverse to a direction of fluid flow through the fluid treatment zone, and (ii) an end of each radiation source assembly is disposed above a predetermined maximum height of fluid flow in the open channel. A first baffle plate is disposed upstream of the fluid treatment zone. The first baffle plate is positioned such that a distal end thereof is below the predetermined maximum height of fluid flow in the open channel. In a preferred embodiment, the present fluid treatment system provides for an area in which a cleaning system for the radiation source assemblies can be “parked” when not in use. In the so-called “parked” position, the cleaning system may be readily accessed for servicing and the like without affecting the flow of fluid through the fluid treatment zone and a fluid treatment system. This is as significant advantage of the fluid treatment system.
Abstract:
A radiation source module comprising a support member, a radiation source assembly connected to the support member, the radiation source assembly comprising at least one elongate radiation source having a source longitudinal axis and a module-to-surface seal disposed on a first elongate surface of the module, the first elongate surface comprising a first longitudinal axis transverse to the source longitudinal axis, the seal operable to provide a substantially fluid tight seal between the first surface and a second surface which is adjacent to the first surface. A fluid treatment system employ the radiation source module is also described.
Abstract:
There is described a water disinfection apparatus comprising a channel for defining a flow of water, and plural ultraviolet light sources, each comprising an elongate ultraviolet lamp unit comprising at least one ultraviolet bulb and defining an elongate lamp unit axis; and a microwave unit comprising a microwave energy source for exciting the at least one ultraviolet bulb. In use, at least part of the elongate lamp unit encounters the flow of water.
Abstract:
An ultraviolet light irradiation apparatus providing combined mechanical and chemical cleaning of light irradiation tubes for removing radiation blocking precipitates from the surface of the tubes. A scraper ring is fitted to the outside of each of the tubes and includes a chamber for receiving a relatively small quantity of cleaning solution. The scraper rings are reciprocated in a sliding action along the tubes which action synergistically acts with the cleaning solution to remove precipitates from the tube surface including fine particles lodged in concave pits in the tube surface.
Abstract:
A fluid disinfection apparatus 10 comprises a disinfection chamber 12 through which fluid to be disinfected flows, and an ultra-violet (UV) lamp 14, operable to output UV light at a germicidal wavelength. First and second fluid inlets 18, 20 and first and second fluid outlets 22, 24 are selectively opened to define a fluid flow path through the disinfection chamber 12. Cleaning apparatus 16 is provided on the UV lamp 14 and comprises a cleaning head 42, a drive plate 46 and four vanes 48. To clean the UV lamp 14, a fluid flow path from the first fluid inlet 18, through the disinfection chamber 12 to the second fluid outlet 24 is defined. Fluid entering the disinfection chamber 12 engages the drive plate 16 and vanes 48, thereby driving the cleaning apparatus 16 along the UV lamp 14 and cleaning the UV lamp 14.
Abstract:
There is described a fluid treatment system comprising an array of independent fluid treatment reactors. The reactors are arranged in a manner whereby a flow of fluid may be passed through the array in a substantially helical direction. The fluid treatment system is capable of treating large volumes of fluid (e.g., water) while requiring a relatively small foot print. In essence, the present fluid treatment system concentrates a relatively large number of radiation sources in a relatively small amount of space resulting in the ability to treat large volumes of fluid (e.g., water).

A radiation source module comprising a support member, a radiation source assembly connected to the support member, the radiation source assembly comprising at least one elongate radiation source having a source longitudinal axis and a module-to-surface seal disposed on a first elongate surface of the module, the first elongate surface comprising a first longitudinal axis transverse to the source longitudinal axis, the seal operable to provide a substantially fluid tight seal between the first surface and a second surface which is adjacent to the first surface. A fluid treatment system employ the radiation source module is also described.
Abstract:
An irradiation device, for example a UV irradiation device for disinfecting waste water, is arranged to emit radiation from a source and through an outer wall which is permeable to fluid. Means are provided for varying the fluid pressure behind the inner surface of the outer wall, to cause fluid to permeate through it, either inwardly or outwardly. The arrangement serves to maintain the outer surface of the permeable wall clear of contaminants.
Abstract:
Systems and methods for cleaning protective sleeves in UV decontamination systems are disclosed. In one embodiment, a system for decontaminating contaminated media includes a translucent sleeve surrounding a light source, and a housing configured to receive the sleeve. A distance between an outer surface of the sleeve and an inner surface of the housing defines an annulus for flowing a contaminated fluid. The system also includes a pump for flowing the contaminated fluid through the annulus. In addition, the system in such embodiments may include a honing material in the contaminated fluid, where the flowing of the honing material against the outer surface of the sleeve removes debris aggregated on the outer surface of the translucent sleeve.
