Abstract: Apparatus for the treatment of organic waste streams is disclosed, in which the organic waste stream is treated in order to reduce the average particle size prior to entry into a biological reactor. The use of a mechanical device to reduce this average particle size while simultaneously mixing the organic waste stream increases the efficiency of the biological reactor. The mechanical device is preferably one which causes attrition and reduction in the average particle size of the organic waste stream. This results in a lower viscosity feed to the biological reactor, and therefore a far more efficient process, which can therefore handle a feed stream of greater concentration than was previously thought to be possible.
