Abstract
A composite support medium for bacteria in sewage treatment plants comprises two intimately associated quantities of media having disparate surface area to volume ratios; in particular a core body of tangled plastics wire-like filaments welded together and having an area to volume ratio of from 60 to 80 square meters per cubic meter partly wrapped in a mat of tangled plastics textile type filaments welded together having an area to volume ratio of from 350 to 450 square meters per cubic meter.

A composite bacteria support medium comprising:
- two proximately arranged component bacteria support media of differing characteristics, a first bacteria support medium having a predetermined surface area to volume ratio and a second bacteria support medium having a substantially different surface area to volume ratio in intimate association with the first medium forming a means for encouraging the growth of substantial numbers of not only higher order but also lower order microorganisms within one said composite medium.
