Abstract:
A process for inhibiting enzymatic activity in a substrate in liquid phase, by the application of denaturing means to the substrate up to a temperature set between 0 and 60 ° C, preferably set between 10 and 50 ° C, and in particular at room temperature. As denaturing means either the application to the substrate of gaseous ozone or the application to the substrate of UV waves for a predetermined time are provided. UV waves and gaseous ozone may also be provided as combined denaturing means, at the same time or in different times, generated by a same device. The substrate to which the invention is applied can be: a food matrix, such as vegetable juice or puree, fruit juice or puree; a pure enzyme or a mixture of enzymes in liquid phase, in particular contained in liquid food; enzymes and mixture of reagents used for biochemical synthesis; waste material where inhibiting the enzymatic activity is necessary before 20 disposal. The process does not damage or affect the substrate and do not apply heat, and successfully inhibits the enzymatic reactions caused by enzymes present in the substrate. The advantage of working at a temperature less than 60 ° , and preferably at room temperature, implies less energy absorption since the substrate must not any more be heated and cooled as required by traditional techniques, as well as it does not affect the characteristics, vitamins and fragrances of the treated food substrates.
Abstract:
Process for the treatment of landfill leachate wastewater having a high COD, said process comprising: taking aliquots of the wastewater from the landfill and mixing them with active charcoal at room temperature, filtering the mixture to obtain an eluate, carrying out a photo-ozonolysis treatment consisting in the simultaneous irradiation with UV-light and saturation with ozone of said eluate.
Abstract:
The patent covers a new and original process for the production of polymeric sulphur. The process involves a crosslinking reaction of molten sulfur with opportune crosslinking agents added with the twofold scope of increasing the yields and to stabilize the polymeric allotrope of sulphur which is formed at high temperature. Furthermore, the new process involves the adoption of a new safer solvent for the purification of the polymeric sulphur and the elimination of the dangerous and toxic CS 2 .
Abstract:
The present invention relates to a filtering device for NBC weapons, comprising a hermetically sealed box structure (10), provided with an opening for the inlet of air and/or gas to be filtered and an opening for the outlet of filtered air and/or gas, and within which one or more plates (11) are arranged to define the walls of a course for said air and/or gas from said inlet and said outlet, the sides of the plates (11 ) facing said course supporting a layer (12) of an adsorbing material.
