Abstract:

Freshwater shortage, energy deficiency, and environmental pollution are three major challenges in the world today. The processes which can address all these challenges simultaneously have received more attention recently. OMBR is a novel high-potential process for wastewater treatment. However, the capability of this process for H₂ production should be assessed. As salinity build-up is one of the major drawbacks of this system that can affect the biological process. Therefore, this study aims to assess the OMBR potential for simultaneous H₂ production and efficient wastewater treatment with considering a proper usage of the salinity build-up through numerical and experimental approaches. All of the potential processes for H₂ production from bio-waste including wastewater along with OMBR have been comprehensively analysed from different aspects to prioritize the potential processes and OMBR capabilities. Furthermore, the effects of different operating parameters including salinity build-up (EC) on water flux in OMBR and on H2 recovery on MEC and fermentation process were modelled and deeply analysed by AI-assisted procedures. Moreover, the back diffusion of Na⁺ and Fe²⁺ from Na-based and Fe-based DS into FS in FO process were experimentally investigated, modelled and optimised using RSM to be used for proper usage of salinity build-up to produce more H₂. The findings showed that OMBR-MEC and fermentation have more priority than the others as a hybrid/combined and single process for H₂ production from wastewater respectively. Moreover, there is a great capability from the aspect of microbial community in OMBR to produce H₂ from wastewater and properly treat wastewater at the same time. All modelling and analysis studies showed a successful performance of AI-assisted approaches in these fields as well as the considerable relative importance of EC (salt ions) in water flux and H₂ recovery. Finally, the applied experimental design approach was successfully used to model and optimise water flux and reverse salt (Na⁺ and Fe²⁺) flux in an FO process. Accordingly, the optimised condition for the proper concentration of salt ions in the FS was obtained using operating parameters control.
