Simultaneous electrolysis method for water treatment and hydrogen recovery

The textile industry is one of the most water-intensive sectors, responsible for around 20% of global industrial water pollution, largely from dyeing and finishing processes. Electrochemical treatment has proven effective for dye degradation and water decolouration, with the additional benefit of pr...

description The textile industry is one of the most water-intensive sectors, responsible for around 20% of global industrial water pollution, largely from dyeing and finishing processes. Electrochemical treatment has proven effective for dye degradation and water decolouration, with the additional benefit of producing hydrogen as a by-product. Although often overlooked, hydrogen is a versatile energy vector with growing importance in industrial decarbonisation strategies worldwide. This project builds on the MesH concept (Mètode d’Electròlisi Simultània per al tractament d'aigües i recuperació d’Hidrogen), which integrates wastewater treatment and hydrogen recovery into a single electrochemical process. To minimise environmental impact and ensure a circular economy approach, the present work evaluates the feasibility of powering the MesH system with photovoltaic solar energy.
