The aim of the presented work was the removal of organic impurities from water using a novel reactor with photoactive textile refill. Titanium dioxide was immobilized on the base textile as a thin layer using sodium silicate as a binding material. The results of studies revealed that the titania-silicate coatings show a high photocatalytic activity towards the azo-dye Acid Red 18 decomposition in water. The prepared coatings exhibit high stability in repeated cycles of water treatment.
