Falling-Film Photoreactors - Photoreactors - Photochemistry

If there is a lack of penetrative depth, photons are absorbed within shortest distance at the boundary surface. The optical path of conventional reactors being far too large, the majority of the volume to be irradiated passes the reactor without exposition to the incident radiation, and, consequently, the photochemical process remains inefficent.
