The invention relates to a bioactive composition for killing cells, comprising at least a first and a second half cell, the half cells being in electrically conductive contact with each other at least by their respective surfaces such that short-circuit elements are generated in the presence of water and oxygen. According to the invention the first half cell comprises at least one semiconductive compound of at least one transition metal element, which exhibits multiple oxidation states and allows a change of the oxidation states by means of catalytically active centers, so that oxygen is reduced and active oxygen species are produced at the first half cell, and wherein the second half cell comprises at least one electrically conductive silver semiconductor which absorbs electrons emitted by the cells or organic material. By means of particles coated with the composition according to the invention, for example, E. coli bacteria can be effectively and reliably killed with both a ruthenium oxide/silver chloride version (a-c) and a ruthenium oxide/silver sulfide version (d-f).

The invention relates to a system for the ionisation of water by electrolysis, for swimming pools, operating by means of mechanical kinetic energy of the water driven from the filtration system of a swimming pool. The invention relates to a system for the ionisation of water of swimming pools or tanks by electrolysis. Said pools or tanks must be provided with a water circulation system. The system can be easily installed in all types of swimming pool without affecting the original character thereof, and uses an autonomous and safe source of energy, the electric power being generated by the kinetic energy accumulated in the water, produced by the driving system for the filtration of the swimming pool water. This energy is used both for the generation of electricity used in the production of ions by electrolysis, and as a source for indicating operation. Kinetic energy is also used as a source of energy for the element for actuating the electrode cleaner.
