Disclosed is a photocatalytic filter which can fully secure a space of gaps to constitute a flow path for flowing a fluid to be disposed of and which has gaps structured for easily trapping an organic substance in the fluid when the fluid is brought into contact with a photocatalyst layer.

Photocatalytic filter, photocatalytic filter device and method for manufacturing photocatalytic filter

Light-transmittable linear photocatalytic filter material that can be arranged in parallel in the longitudinal direction without causing a filter to have the form of a barrel when the filter is made of a bundle of a number of such photocatalytic filter materials, each comprising a light-transmittable linear material, a number of particulate materials bonded to an outer side surface of the light-transmittable linear material and a photocatalyst layer formed on said outer side surface and said number of particulate materials, wherein a maximum value of heights from said outer side surface to said photocatalyst layer in a central region of said light-transmittable linear material in the longitudinal direction is smaller than a maximum value of heights from said outer side surface to said photocatalyst layer in regions of both ends thereof.

Light-transmittable linear photocatalytic filter material, filter to which the material is applied, and process for production thereof

Light-leakage type photocatalyst fibers ( ) are bundled together to form a filter assembly having an enormous number of minute gaps which provide fluid communication paths in a longitudinal direction of the photocatalyst fibers. Light is incident to each of the photocatalyst fibers constituting the filter assembly while an object fluid to be processed is introduced through an end face of the filter assembly to pass through the gaps among the photocatalyst fibers in the longitudinal direction.

Photocatalyst filter for a light leakage type

A photocatalyst is carried on a surface of a light guiding body for guiding light needed to activate the photocatalyst in such a manner the light guided by the light guiding body irradiates directly from the surface of the light guiding body the photocatalyst.
