Brochier technologies : photocatalytic pollution control solution


Brochier Technologies is a french company specialised in optical fibre weaving solutions for light applications in lighting, communications, safety, pollution control, and medical fields. 

Lightex technology

The company is well kown for its Lightex® technology which consists in the weaving of optical fibres with lateral lighting, connected to electroluminescent diodes that makes possible to create flexible or rigid illuminated surfaces, very thin, requirering low power consumption and providing long life span.The Lightex® lighting solutions are protected by several international patents.

UVtex technology : Environment application

Brochier technologies has also developed UVtex technology which is a photovoltaic pollution control solution using optical fibre plastics and UV light ( patented technology).By combining the ultraviolet radiation distributed by the optical fibre fabric with some quantity of TiO2, the UVtex® technology acts upon pollution control of the air, the water, and the destruction of odours, therefore being an answer to many current environmental problems of today.

Photocatalysis

Air purification, odor control, cleaning the surface ... The industrial applications of photocatalysis are numerous today. And to think the French Federation of photocatalysis (FFP), established in 2006 to promote the use of this process, the technological potential of the photocatalyst is still under exploited. Limitation of bacterial growth in hospitals and medical, water purification, water purification, detoxification of water rinsing equipment or industrial agriculture, elimination of odors could be part of the field of development of this technology is discovered more than 
fifty years.

The principle? Decomposition and degradation of the material under the action of light beams on the surface of a catalyst. A catalyst, usually titanium dioxide (TiO2), is activated by the presence of a light source, natural or artificial. Free radicals released by the titanium allow oxyréduction: organic molecules on the surface are adsorbed and decomposed by the catalyst. Titanium dioxide, inert compound used as a pigment in paints and cosmetics, is the raw material chosen by most manufacturers because, according to the FFP, as it is in contact with light, and pollutants, the material remains stable and efficient.
