Data underlying the publication: Membrane biofilm reactor (MBfR) enabling optimized H2 delivery and supporting minimal nutrient supplementation to hydrogenotrophic biofilms

This dataset contains data collected during experiments developing a Membrane biofilm reactor (MBfR) for optimized H2 delivery and supporting minimal nutrient supplementation to hydrogenotrophic biofilms. The objective of the research was to investigate the long-term performance of an MBfR used for hydrogenotrophic methanogenesis. The laboratory-scale MBfR was operated for 437 days, 396 of which were without additional nutrient supplementation. Numerous liquid and sludge samples were collected and analyzed over the experimental period. Reactor performance was evaluated based on the content of the product gas (CH₄), the production rate of CH₄, and the conversion efficiency of CO₂ and H₂. The concentration of nutrients in the liquid and sludge phases over the long term was assessed and related to reactor performance. This research data is being made public both to act as supplementary data for publication and in order for other researchers to use this data in their own work. This work was performed at Wetsus, European Centre of Excellence for Sustainable Water Technology.

本数据集收录了膜生物膜反应器（Membrane biofilm reactor, MBfR）开发实验的相关实验数据，该反应器旨在优化氢气输送效率，并为嗜氢生物膜提供最低限度的营养补充。本研究的目标为探究用于嗜氢产甲烷的膜生物膜反应器的长期运行性能。该实验室规模的膜生物膜反应器持续运行437天，其中396天未添加额外营养物质。实验期间共采集并分析了大量液相与污泥样品。反应器性能通过产物气体中的甲烷（CH₄）含量、甲烷生成速率以及二氧化碳（CO₂）与氢气（H₂）的转化效率进行评估。本研究还对长期运行过程中液相与污泥相内的营养物质浓度进行了测定，并分析其与反应器性能的关联。本研究数据公开，既可作为已发表论文的补充数据，也可供其他科研人员在其研究中使用。本研究工作在欧洲可持续水技术卓越中心（Wetsus）完成。
