Abstract:
An apparatus for low flux photocatalytic pollution control comprising:means for inputting a target pollutant, said means adapted to provide a varying flow rate;a low flux longitudinal light source having a first end and a second end;a first stage photocatalytic reactor having a first length about the first end of the light source, for converting a first portion of the varying flow rate target pollutant to a pre-determined level of destruction and removal efficiency(DRE) by passing the target pollutant through the first stage photocatalytic reactor; anda last stage photocatalytic reactor having a second length about the second end of the light source for converting a last portion of the target pollutant passing through the last stage photocatalytic reactor a selected final DRE level; anda photocatalytic means in each of the first stage photocatalytic reactor and the last stage photocatalytic reactor for converting the first portion and the last portion of the target pollutant to the predetermined DRE level and the selected final DRE level, the photocatalytic means having a solely organic polymer substrate for a catalyst, adapted to operate below a sol-gel processing temperature.
