Definitions
- ZiB. be produced by applying the photocatalytically active semiconductor substance, for example to a glass frit.
- the pore sizes of the filter should be small enough so that the dissolved pollutant molecules come into contact with the exposed part of the TiO 2 wall during the filtering process. Also advantageous are pore sizes that meet the conditions for a Knudsen diffusion of the pollutant molecules. It has been shown that the suitable pore diameters are in the size range from 10 to 100 ⁇ m.

Abstract
Procédé et dispositif de purification de liquides et notamment d'eau, contaminés par des impuretés inorganiques et/ou organiques. Les impuretés sont transformées et/ou précipitées par l'utilisation des propriétés catalytiques et photocatalytiques de semi-conducteurs, si nécessaire avec l'addition d'un oxydant. A cette fin, on applique un semi-conducteur sous la forme d'au moins une couche semi-conductrice, par exemple une couche poreuse, sur un substrat également poreux (17), afin de réaliser un filtre pouvant être activé par la lumière d'au moins une lampe (22), par lequel s'écoule le liquide qui est ainsi purifié. Le stimulus lumineux engage des réactions d'oxydoréduction à la surface de la couche semi-conductrice, conduisant à la transformation de substances chimiques nocives, ou à la précipitation de métaux nobles dissous.
