Abstract
A method and apparatus for treatment of biodegradable waste products. The influent is aerated and directed through a fixed media assembly to promote intimate surface contact and cause microbial growth. The fixed media assembly comprises a stack of spaced apart, parallel, substantially vertical corrugated sheets. The corrugations are defined by obliquely inclined peaks and valleys and are oriented so that the corrugations of immediately adjacent sheets intermate with one another so as to define an inclined sluffing channel at each corrugation to provide a substantially unobstructed pathway therethrough while inducing turbulence and mixing.
