520			_aCoconut fibre has exccellent microbial attachment properties. For coconut fibre to be a suitable medium for biological waste water treatment, it is necessary to arrange them in a systematic configuration. The bottle brush type is one such suitable configuration. This suitability is made practical by fixing coconut fibres in bottle brush like configuration using a flexible inert low cost non-metal material as the binder. This configuration enables us to preset the required surface area and voids per unit volume eqully distributed and to fix the medium in a structurally stable structure. These features are very important specially for the maximum efficiency of closed anaerobic reactors. This comparatively low cost medium provides the user with a greater effective reactor volume as it only occupies a small volume of the reactor. It occupies less than 3;of the reactor volume when the surface area is set to the level for the maximum efficiency of a reactor for normal crepe rubber waste.
