NOVELTY - An apparatus for processing and treating sewage comprises: (1) a conical section with an inlet tube; (2) a rotor, for creating reverse vortices upstream in a cyclonic air-stream; and (3) a feed inlet tube for feeding the sewage into a centripetal boundary envelope in the conical section within the reverse vortex for treating and processing the sewage in the conical section and rotor.    USE - The apparatus and methods are used for processing and treating sewage and biosolids. It can also be used to dry wet clay, paper pulp, as well as fish and bones into a fine powder.    ADVANTAGE - The apparatus is capable of processing materials, e.g., biosolids, efficiently while minimizing wear of the rotor or fan. The processing technique leads to removal of some pathogens and dries the sewage at the same time. The cost of treating sewage using the apparatus is reduced and it enables sewage companies to substantially reduce transport costs. The treatment method conforms to microbiological treatment regulations specified in the 40 CFR Part 503 by the United States Environmental Protection Agency (Class A or B specifications). The end product of the sewage treatment can be used in many applications such as fertilizer or to generate electricity. The products of the process can also be used in agriculture as fertilizers or animal food or for gardening or horticultural practices, e.g. creating improved lawns or playing fields. The apparatus is capable of grinding a material down by 1500:1, which is comparable with prior art devices which only achieve a reduction of 4:1.    DETAILED DESCRIPTION - An apparatus for processing and treating sewage (300) comprises:    (a) a conical section (320) with an inlet tube;    (b) a rotor (310), for creating reverse vortices upstream in a cyclonic air-stream, having an inlet for the movement of the air-stream and sewage and an outlet corridor with an exit tube; and    (c) a feed inlet tube (325) for feeding the sewage into a centripetal boundary envelope in the conical section within the reverse vortex for treating and processing the sewage in the conical section and rotor.    INDEPENDENT CLAIMS are also included for:    (1) a rotor (310) for a sewage processing treatment comprising:    (i) a central hub (312) having a diameter which is no more than 13% of the rotor's diameter; and    (ii) 9 or 10 blades, extending radially from the hub for creating reverse vortices upstream in a cyclonic air-stream, which extend forwards from the hub of the rotor at an angle of 45 degrees; and    (2) a method for treating biosolids comprising a sewage processing and treatment apparatus. The biosolids are sewage, sewage sludge, municipal sewage sludge, septage, manures, animal waste, slaughter house offal, pharmaceutical fermentation waste, industrial biosolids, agricultural wastes, food wastes, spent hens, paper mill waste or borgass.
