ABSTRACT:
A fluidized bed reactor for the biological treatment of a fluid includes granular treating material through which the fluid to be treated passes upwardly, thereby fluidizing the treating material, during which biological treatment is achieved. A homogeneous distribution of the fluid into the bottom of the granular treating material is achieved by providing a granular transfer material beneath the granular treating material, and introducing the fluid to be treated into the granular transfer material at a speed and under conditions sufficient to impart movement to the granular transfer material causing uniform distribution of the fluid and uniform diffusion thereof upwardly into the granular treating material at a speed sufficient to achieve fluidization thereof.
