The present invention concerns a method for reducing the amount of polluting and/or valuable elements through application of electrolysis, in particular of the electrocapturing phenomenon. The electrolysis according to the present invention is applied permanently over time in a polluted water body. The predetermined action area (115bis, 115ter) preferably has a smaller extension than the water body. The at least one phenomenon (125bis, 125ter) is preferably powered electrically through production of electrical energy in loco through at least one renewable energy source (140). The method is suitable for purifying large expanses of water, like seas, lakes, lagoons and rivers, through plants operating permanently, however this does not rule out other applications.

A portable electrolytic water purifier includes a housing, a base, a first conducting grid plate, a second conducting grid plate and an electrolytic circuit module. The housing has a container coupling portion. The base is mounted inside the housing and has an assembly ring connected with the container coupling portion. The second and first conducting grid plates are respectively mounted inside the assembly ring, are overlapped in a top-down manner, and are located under an opening of the container coupling portion. The electrolytic circuit module is mounted inside the housing and is electrically connected to the first and second conducting grid plates. After a container filled with water is inversely placed on the water purifier, the first and second conducting grid plates are immersed in water to decompose the water into electrolyzed water through electrolysis.

A photodialysis device that can desalinate saline streams is described herein. The device can have a desalination rate that is significantly faster than current solar thermal desalination technology. Salt is removed from water by passing ionic current derived from sunlight through this water using dye-sensitized membranes. The device can serve as a distributed, low-cost technology that can efficiently and effectively desalinate low salinity sources of water, which is particularly useful for agriculture and drinking water applications.

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.

The present disclosure provides systems and methods for enhancing production of an aquaculture pond. The systems generally comprise a photo electrolysis array that includes an electrolyzer module and a photovoltaic cell. The electrolyzer module is operable to produce hydrogen and oxygen. A diffuser diffuses the produced oxygen into the aquaculture pond water, thereby increasing the concentration of oxygen in the aquaculture pond.

A water-disinfecting apparatus includes a vessel with a cathode, an insert with a photoanode, an ultraviolet light source configured to be positioned in the insert, and a power source. The cathode forms an electrically conductive layer on an inner surface of the vessel. The photoanode is configured to be positioned in the cathode. The power source is configured to be operably coupled to the cathode, the photoanode, and the light source.
