Membrane-based technologies for post-treatment of anaerobic effluents

Abstract

Anaerobic digestion-based p interest. However, apart from point of view, including pos ingen discharge standards 1,2 ocesses for converting wastewateinto'r clean water and energy are attracting ever-growing indu the microbial digestion step, current technologies require further progress from an integrated process reatment steps. Anaerobic effluents normally undergo extensive post-treatment steps to meet while valuable nutrients are rarely recovered. Additionally, a significant portion of the produced methane remains inevitably dissolved in global warming concerns. To address these issues, severa he effluent,hich is eventually released into the environment, causing economic loss and embrane-based technologies show significant promise. Here review current progress in membrane-based recovery of isso ve methane'and nutrients, highlighting opportunities where; embrane-based technologies can improve the post-treatment of anaerobic effluents. Lastly, we also share our perspective research directions and how to secure the competitiveness of membrane-based technologies for anaerobic wastewater reatment processes, focusing on currenthallenges for membrane development, Wofoulin on strategies, and small-scale o large-scale implementation.
