Abstract

A process and apparatus for the treatment of flowable waste in a waste treatment reactor and in particular the treatment of waste water in a bioreactor (20) containing a bed of support particles (24) having an attached biofilm and entrapped microorganisms are described. The process includes the steps of intermittently introducing waste water through a discharge port (34) adjacent a bottom surface (36) of the bed (20) to form a series of plugs of waste water integrated with the microorganisms; and maintaining a quiescent period following each introduction of waste water to promote biological degradation of contaminants.
