5192428 Portable system for treating human waste
PATENT ABSTRACTS

the chlorine dioxide in the treatment solution which attacks and destroys the infectious constituents of the waste, thereby decontaminating the waste. Upon dewatering, the decontaminated waste is suitable for landfilling. Process control is exercised by controlling the temperature of the aqueous solvent. A solvent temperature is selected which optimizes both the chlorine dioxide concentration in the treatment solution and the reactivity of the chlorine dioxide with the infectious constituents. Continuous monitoring of the chlorine dioxide concentration in the treatment solution enables adjustment of the solvent preheat temperature to optimal values in accordance with the dynamics of the treatment system.
5192428 PORTABLE SYSTEM FOR TREATING HUMAN WASTE Carl Lindstrom assigned to Clivus Multrum Inc A new portable system is disclosed for composting feces and for treating urine includes a composting retainer which includes a composting means for exposing the feces to sufficient air and water to allow the feces to compost, thereby forming a compost product. A urinetreatment retainer with aerobic nitrifying bacteria disposed on a substrate whereby urine is treated by the bacteria, thereby forming a liquid product. A means is available for transporting the portable system.
homogeneous suspension in this water, and is maintained at a more or less constant mass concentration; this water and this granular material in suspension are circulated in a separation zone from which is extracted on the one hand clarified water, and on the other hand biomass loaded granular material; and almost all of the active biomass fixed on said granular material is brought back by forced recycling to the mixing zone.
5192456 APPARATUS FOR TREATING ACTIVATED SLUDGE AND METHOD OF CLEANING IT Hiroshi Ishida, Yutaka Yamada, Kiyoshi Izumi, Masashi Moro, Paris, assigned to Kubota Corporation An activated sludge treating apparatus for use in treating wastewater, such as gray water and sewage. A plurality of filter membrane modules are vertically arranged in parallel at predetermined intervals within a treating tank. The water to be treated which is stored in the treating tank is separated into solid and liquid by the filter membrane modules, and water that has passed through the filter membrane modules is extracted as treated water. An agitating device is disposed at a level below the filter membrane modules.

BY N I T R I F I C A T I O N A N D / O R DENITRIFICATION, OF AN EFFLUENT INCLUDING NITRATED POLLUTION Jacques Sibony, Gilbert Desbos, Paris, France assigned to Omnium de Traitements et de Valorisation (OTV) A process for the biological treatment by nitrification and/or denitrification of an effluent containing nitrogen pollution includes the following steps: an incident flow of this water is brought into a mixing zone with at least one compartment in which, by turbulent mechanical agitation, an inconsumable and insoluble granular material, loaded with biomass, is put in

SYSTEM
Margre Augustine, Carl N Hodges, Linda S Leigh assigned to Space Biospheres Ventures Solutions containing pesticide wastes from greenhouses, for example, are decontaminated in a system including a soil bed reactor. Waste water from the greenhouse goes to a sample tank from which samples are withdrawn for assay of toxicity. Water from the sample tank goes to a holding tank, or to a downstream subsystemif toxicity level is low. Water in the holding tank is aerated to promote degradation of toxic materials. Water from the holding tank is applied near the upper surface of a layer of soil in the soil bed reactor. Air from the sample tank and holding tank, and intermittently, air conraining pesticides from the greenhouse, is also passed through the layer of soil in the soil bed reactor. Microbial action in the soil degrades
