ABSTRACT:
Apparatus for the purification of a fluid, such as water, which in the presence of light of an activating wavelength brings the fluid into contact with surfaces with fixed photoreactive coatings of anatase (TiO.sub.2) or other photoreactive semiconductors, thereby detoxifying, reducing or removing organic pollutants therefrom. The apparatus includes a nontransparent substrate coiled longitudinally and helically around a transparent sleeve. The nontransparent substrate has photoreactive semiconductor material bonded thereto. The nontransparent substrate defines a helical path through an annular cylindrical housing.
