NOVELTY - An apparatus for treatment of feces comprises tank (200) for housing feces; process vessel (202) in which the feces is treated and which is located inside tank; inlet (204); rotary device (300) for stirring feces in process vessel and for introducing oxygen into feces; motor (232) for driving rotary device; partitioning member (212) separating interior of process vessel in lower (216) and upper (218) portion; where rotary device is arranged to cause a suction of material mainly from lower compartment in first mode of operation and into rotary device.    USE - As an apparatus for treatment of feces (claimed).    ADVANTAGE - The apparatus eliminates the health problem caused by the presently used primitive latrines and produces valuable fertilizer directly usable by farmers. The apparatus treats the urine and feces on a continuous basis and rapidly transform the feces to virtually bacteria free harmless end products in the form of a nitrate-rich liquid phase and a phosphorus-rich slurry or semi-solid phase. These end products can be directly pumped or transported onto nearby fields to provide cheap fertilizer and thus increase crops. The apparatus constitutes a self-contained system for taking care of feces and treating it to produce cheap fertilizer thereby improving life for poor farmers in developing countries.    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following:    (1) rotary device for use in apparatus comprising upper and lower compartments separated by partition plate; hollow driving shaft attached to partition plate in the centre, and communicating with the lower compartment via hole in the partition plate; where upper and lower compartments are formed by truncated cone having the narrower part facing upwards or downwards such as to leave annular opening around centrally located shaft, and further having openings provided in wall of upper compartment; where the cone is attached to bottom side of partition plate via impeller blades, distributed evenly along periphery of cone, thus forming peripheral opening from compartment; and    (2) treating feces involving feeding fragmented feces to process vessel; stirring feces vigorously within process vessel while supplying air to mix it thoroughly with oxygen; letting treated feces flow over to storage tank; optionally feeding stored and treated material from storage tank into process vessel for further treatment.    DESCRIPTION OF DRAWING(S) - The figure shows schematic view of apparatus for treatment of feces.
