In addressing wastewater treatment challenges, developing integrated systems to reduce greenhouse gases, produce green energy, and achieve sustainable development is crucial. This study developed an integrated electrobiomembrane reactor for simultaneous biohydrogen (bioH2) production from energetic poplar leaves using the dark fermentation (DF) process, conventional H2 production, bioenergy generation, and saline water desalination in a single system.
The results revealed that pH was a key factor in bioH2 production, with optimal production of 40.2 mL/g-biomass achieved at pH 5.5. Maximum current and power density values were 2861.7 mW/m² and 2819.4 mA/m² at the same pH under improved conditions. Additionally, maximum conventional H2 production was 1341.6 mL using a 2 M KOH solution.
Overall, the integrated system demonstrated high efficiency in desalination, energy production, and both conventional and biological H2 production, making it a promising solution for industrial applications.
