Abstract:
1. A reactor unit for photocatalytic treatment of fluids including a housing, a catalyser device comprising a catalytic material support being formed from a plastic material and having a generally tubular shape defining a fluid flow channel extending around and along a fluid flow path, and a radiation source received in a central axis of the catalyser device, wherein the catalytic material support comprises a wall portion and a plurality of tapered protrusions extending from an internal surface of the wall portion to a tip positioned at a distance to the radiation source within a range of 0 to 50% the distance separating the radiation source and the internal surface of the wall portion, the tapered protrusions being arranged around the central axis of the radiation source and along the fluid flow channel, and the tapered protrusions have an average height to average base diameter ratio in a range from 6:1 to 1:1, wherein the catalytic material support is in contact with the whole internal surface of the housing, and wherein the internal surface of the wall portion and the protrusions are coated with a photocatalytic material defining meandering air paths through the fluid flow channel around the central axis.
