Abstract

Water scarcity and wastewater pollution are major health issues, yet traditional wastewater treatment technologies are limited by high operational costs and energy demands, and membrane fouling. Here we review low-cost ceramic membranes for wastewater treatment and bioenergy production, with emphasis on bioreactors, and microbial fuel cells to generate electricity. Ceramic membranes display high filtration performance and resistance to harsh conditions, achieving water flux rates up to 250 L/m² per h, significantly outperforming polymeric membranes. Ceramic membranes are now affordable due to recent advances in as clay-based ceramics, extrusion and electrospinning. Ceramic membranes integrated into microbial fuel cells and anaerobic bioreactors could enhance power generation by 20% and biogas yield by 15–30%. Surface modifications and nanomaterial use have reduced fouling by up to 60%, yet issues of biofouling and high fabrication costs persist.

利用高性价比的陶瓷膜从废水中生产生物能源的研究进展

水资源短缺和废水污染是主要的健康问题，然而传统的废水处理技术受到高运行成本和能源需求以及膜污染的限制。本文综述了用于废水处理和生物能源生产的低成本陶瓷膜，重点介绍了生物反应器和用于发电的微生物燃料电池。陶瓷膜显示高过滤性能和耐恶劣条件，实现水通量高达250升/平方米每小时，显着优于聚合物膜。由于粘土基陶瓷、挤压和静电纺丝的最新进展，陶瓷膜现在是负担得起的。将陶瓷膜集成到微生物燃料电池和厌氧生物反应器中可以提高20%的发电量和15-30%的沼气产量。表面改性和纳米材料的使用已经减少了高达60%的污染，但生物污染和高制造成本的问题仍然存在。

期刊介绍： Environmental Chemistry Letters explores the intersections of geology, chemistry, physics, and biology. Published articles are of paramount importance to the examination of both natural and engineered environments. The journal features original and review articles of exceptional significance, encompassing topics such as the characterization of natural and impacted environments, the behavior, prevention, treatment, and control of mineral, organic, and radioactive pollutants. It also delves into interfacial studies involving diverse media like soil, sediment, water, air, organisms, and food. Additionally, the journal covers green chemistry, environmentally friendly synthetic pathways, alternative fuels, ecotoxicology, risk assessment, environmental processes and modeling, environmental technologies, remediation and control, and environmental analytical chemistry using biomolecular tools and tracers.
