A METHOD OF DEGRADING CONTAMINANTS / POLLUTANTS FROM A MATERIAL AND STRUCTURES FOR CARRYING OUT SAID METHOD

摘要

A method of removing contaminants from liquid passing over a surface by applying a photocatalyst to said surface 2, such that when a liquid passes over said surface in the presence of solar power, contaminants are degraded to less harmful compounds in said liquid. The photocatalyst is typically titanium dioxide applied as a coating on a surface such as glass or metal and can be used to degrade contaminants in effluents from industrial processes such as the textile or paper industries when liquid from those processes flows over the coating.
