Application of Reactor with the Photoactive Refill for Decomposition of Organic Pollutants in Water

The aim of the presented work was removal of organic impurities from water using a novel reactor with photoactive refill. Titanium dioxide (Chemical Factory "Police" Poland) was immobilized on the base material as a thin layer from the alcoholic suspension followed by thermal stabilization. The glass fabric was applied as a support for the titania coating. The results of studies revealed that the titania coatings show a high photocatalytic activity toward the model organic compounds decomposition in water. The prepared coatings exhibit high stability in repeated cycles of water treatment. The proposed reactor with photoactive refill solves the problem of necessity of replacement of the reactor or the parts of the reactor. When the photocatalysts activity decreases, only the photoactive refill can be easily replaced. Application of glass fabric is advantageous since it is resistant to UV light and does not undergo the photocatalytic decomposition on the contrary to the natural fabrics.
