Abstract
Turbulent mixing in a UV system is increased by positioning one or more ring-shaped devices, such as washers, at one or more predetermined locations on the exterior surface of each lamp unit in the system. The washers may have the same or different diameters. Turbulent mixing is also increased by retaining the upstream end of each lamp unit in a ring-shaped device, alone or in combination with washers positioned on each lamp unit exterior surface as described above.
Claims17
Apparatus for treating a fluid flowing in a canal, comprising:
- a plurality of support members for holding radiation sources in the canal;
- a plurality of radiation sources coupled to each of said plurality of support members, each radiation source disposed with its longitudinal axis substantially parallel to a direction of fluid flow in the canal, each said radiation source having an upstream end and a downstream end;
- and
- a plurality of turbulence increasing devices respectively coupled to the upstream ends of said plurality of radiation sources, for causing fluid turbulence in the canal in the spaces between said plurality of radiation sources.
A device for irradiating a fluid flowing in a canal, comprising:
- a vertically-extending support member for holding radiation sources in the canal;
- a plurality of radiation sources coupled to said vertically-extending support member, each radiation source having an upstream end and a downstream end, the upstream end of each radiation source being coupled to said vertically-extended support member such that a longitudinal axis of said each radiation source is disposed in the canal substantially parallel to the direction of fluid flow;
- and
- a plurality of turbulence-increasing members respectively coupled to the upstream ends of said plurality of radiation sources, for increasing turbulence in the fluid flowing in the canal between the radiation sources.
An ultraviolet water treatment system for irradiating water flowing in a canal, comprising:
- a two-dimensional matrix array of ultraviolet radiation assemblies disposed in the canal, each radiation assembly including an ultraviolet source and a sleeve surrounding said source, each ultraviolet source being disposed in the canal with its longitudinal axis substantially parallel to a direction of water flow in the canal;
- a plurality of turbulence-generating members respectively connected to an upstream end of each said radiation assembly, said plurality of turbulence-generating devices causing turbulent flow in the water in the canal between the plurality of sleeves.
Apparatus for increasing turbulence in a radiation water treatment system having a plurality of radiation sources disposed in a canal, comprising:
- a device disposed on a upstream end of each of said plurality of radiation sources, each said device causing turbulent flow in the canal in a space between each of said plurality of radiation sources and an adjacent radiation source.
