Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods are inadequate for effectively and cost-efficiently reducing the concentration of harmful polluting elements like Cadmium, Lead, Mercury, Aluminium, Antimony, Arsenic, Tin, and Uranium in large water bodies, which poses health risks and environmental contamination, especially in aquatic ecosystems.
Innovation Solution
The method employs electrolysis through an electrocapturing phenomenon using insoluble electrodes and renewable energy sources to selectively capture and deposit polluting elements from water, allowing for their reuse, with a focus on long-term, low-intensity application to minimize invasiveness and maximize pollutant removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional purification methods are applied to large water bodies, then pollutant removal efficiency is improved, but operational costs and system complexity increase significantly
Solution Approach 1:
The patent divides the large water body into multiple treatment zones, each equipped with electrodes of different polarities. This segmentation allows parallel processing of pollutants across different areas, improving overall removal efficiency while keeping each individual treatment zone simple and manageable in complexity
Solution Approach 2:
The electrode system serves multiple functions simultaneously: it attracts and removes various types of pollutants (metals, organic compounds, suspended particles) through electrostatic attraction, and also enables resource recovery by concentrating valuable materials on electrode surfaces for subsequent harvesting
2Loss of time
If intensive electrolysis is applied to rapidly reduce pollutant concentration, then treatment time is reduced, but energy consumption and operational costs increase
Solution Approach 1:
The system operates electrodes in periodic cycles, alternating between high-intensity pollutant attraction phases and lower-intensity maintenance phases. This periodic operation maintains effective pollutant removal over time while significantly reducing average energy consumption compared to continuous intensive electrolysis
Solution Approach 2:
The patent applies electrolysis at moderate intensity levels continuously over extended periods rather than using high intensity for short durations. This partial action approach achieves comparable pollutant removal while consuming less total energy, as the electrostatic field maintains effectiveness without requiring maximum power input
3Productivity
If invasive purification interventions are implemented to achieve rapid pollutant removal, then pollutant concentration reduction is improved, but environmental disruption and system invasiveness increase
Solution Approach 1:
The electrode system acts as a gentle intermediary that attracts pollutants through electrostatic fields rather than through invasive mechanical or chemical interventions. This mediator approach allows pollutant removal while maintaining natural water flow patterns and minimizing disruption to aquatic ecosystems
Solution Approach 2:
The system converts the harmful presence of dissolved pollutants into a beneficial concentration effect by using electrostatic attraction to gather dispersed contaminants onto electrode surfaces, transforming a diffuse pollution problem into a concentrated, easily removable form while preserving the natural state of the water body
4Quantity of substance
If polluting elements are removed from water for disposal, then water purity is improved, but resource loss and economic value decrease
Solution Approach 1:
The system is designed to recover polluting elements rather than dispose of them. Valuable metals and materials are concentrated on electrode surfaces through electrostatic attraction, then harvested and reused as resources, transforming what would be waste into recoverable materials and eliminating resource loss

AI summary
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.
