Abstract: The present invention relates to a method for treatment of substance having a content of organic material, e.g. manure from stables (1). The substance is initially separated into a first liquid phase and a first sludge phase, and an oxidation is performed, preferably by ozone, on at least one of the phases of the substance. From the first sedimentation process or flotation process the first sludge phase is separated, and a second sedimentation or flotation process is performed on the first liquid phase, preferably by addition of a polymer, and from the second sedimentation process or flotation process a second liquid phase is passed on to a further separation process, in which separation process a further oxidation, preferably by ozone, is performed on the second liquid phase. Preferably, the ozonation is substantially saturated. An important advantage is that malodour from the substance may be significantly reduced, possibly even eliminated.

Abstract: The present invention relates to a system for removal of airborne contaminants in a confined space comprising a primary reaction chamber which chamber comprises at least one ultraviolet light tube for the generation of ozone, in which chamber air coming from the confined space is treated with a combination of UV radiation and ozone. It is an object of the invention to provide a system for removal of airborne pollutants in confined spaces, such as a livestock stable. A further object of the invention is to overcome the problem of dust accumulation on the ultraviolet light emitting lamp and production of nitrogen containing toxic gases.

Abstract: This invention relates to cyclic peroxide compositions, a process of producing the compositioning and a method for inhibiting tumors utilizing the compositions. More particularly, the compositions are cyclic peroxides which are derived from marine organisms, i.e., the marine sponge Plakortis lita.
