NOVEL PHOTOCATALYTIC REACTOR FOR WATER-PURIFICATION

A novel photocatalytic reactor design for water treatment is character ized by the use of new extremely narrow diameter lamps, thus allowing for much higher surface area for catalyst coating per unit reactor vol ume and consequently for much higher specific reactor capacity. Experi ments in a reactor containing 21 novel U-shapen lamps coated with cata lyst showed a 695% increase in efficiency of the reactor performance i n comparison with a classical annular reactor and 259% in comparison w ith a slurry reactor. Both a classical annular reactor and a slurry re actor cannot be scaled up for large-scale applications due to the low values of illuminated catalyst surface area per unit volume of liquid treated inside the reactor while this configuration is flexible enough for large-scale applications.
