Abstract: The invention relates to the field of agriculture and, in particular, to products for improving agricultural crop yields. More specifically, the present invention relates to a strengthening composition that regulates transpiration and protects leaves and fruits, said composition containing zeolite as a base, preferably zeolite 4A, and other additives which boost the activity thereof and facilitate the application of same in an aqueous suspension or dry. In addition, the invention relates to the different uses of said composition.

Abstract: A first aspect of the invention consists of a photocatalytic mixture designed to obtain degradation of nitrogen oxides through synergic combination of the two compounds: TiO2, in any of its crystalline phases or in amorphous state, and one or various feldspars such as carnegeit or nepheline. A second aspect of the invention consists of obtaining said combination giving rise to products with the capacity to degrade nitrogen oxides.

Abstract: The invention relates to a method, devices and reagents which are used for Fenton reaction-based wastewater treatment. According to the invention, the oxidation reaction of the organic material with the oxygenated water is performed in the main oxidation reactor (12) in the presence of metallic catalysts. The Fenton reaction takes place in the reactor at absolute pressure of between 1 Kg/cm2 and 1.5 Kg/cm2 and at a temperature of between 110° C. and 120° C. Once treated and cooled, the effluent is conveyed to zone D to a neutralising tank (6) in which the pH is increased to a value greater than seven, thereby causing precipitation of the hydroxides. In addition, safety checks are carried out automatically.
