ABSTRACT:
The present invention provides a reactor for the biological processing of fluid such as domestic or industrial waste water or the like, the reactor comprising a plurality of substantially horizontal layers of growth medium stacked one above the other, and having a colonizing biofilm thereon during use, the reactor being arranged to cause the path of flow of the fluid to reverse from one layer to the next, in order to maximize the length of the path of flow for a given footprint of the reactor.
