Pilot plants of membrane technology in industry: Challenges and key learnings

Colin A. Scholes

《化学科学与工程前沿（英文）》 2020年第14卷第3期页码 305-316 doi: 10.1007/s11705-019-1860-x

摘要： Membrane technology holds great potential in gas separation applications, especially carbon dioxide capture from industrial processes. To achieve this potential, the outputs from global research endeavours into membrane technologies must be trialled in industrial processes, which requires membrane-based pilot plants. These pilot plants are critical to the commercialization of membrane technology, be it as gas separation membranes or membrane gas-solvent contactors, as failure at the pilot plant level may delay the development of the technology for decades. Here, the author reports on his experience of operating membrane-based pilot plants for gas separation and contactor configurations as part of three industrial carbon capture initiatives: the Mulgrave project, H3 project and Vales Point project. Specifically, the challenges of developing and operating membrane pilot plants are presented, as well as the key learnings on how to successfully manage membrane pilot plants to achieve desired performance outcomes. The purpose is to assist membrane technologists in the carbon capture field to achieve successful outcomes for their technology innovations.

Recent advances in membrane bioreactor technology for wastewater treatment in China

Xia HUANG, Kang XIAO, Yuexiao SHEN

《环境科学与工程前沿（英文）》 2010年第4卷第3期页码 245-271 doi: 10.1007/s11783-010-0240-z

摘要： Since the introduction of the membrane bioreactor (MBR) in China in the early 1990s, remarkable progress has been achieved on the research and application of this technology. China has now become one of the most active fields in the world in this regard. This review outlines the development of MBR-based processes in China and their performance of treating municipal and industrial wastewaters. Since membrane fouling is a critical operational problem with MBR processes, this paper also proposes updated understanding of fouling mechanisms and strategies of fouling control, which are mainly compiled from publications of Chinese researchers. As for the commercial application of MBR in the country, the latest statistics of large-scale MBR plants (>10000 m·d) are provided, and the growth trend of total treatment capacity as well as its driving force is analyzed.

Membrane bioreactors for hospital wastewater treatment: recent advancements in membranes and processes

《化学科学与工程前沿（英文）》 2022年第16卷第5期页码 634-660 doi: 10.1007/s11705-021-2107-1

摘要： Discharged hospital wastewater contains various pathogenic microorganisms, antibiotic groups, toxic organic compounds, radioactive elements, and ionic pollutants. These contaminants harm the environment and human health causing the spread of disease. Thus, effective treatment of hospital wastewater is an urgent task for sustainable development. Membranes, with controllable porous and nonporous structures, have been rapidly developed for molecular separations. In particular, membrane bioreactor (MBR) technology demonstrated high removal efficiency toward organic compounds and low waste sludge production. To further enhance the separation efficiency and achieve material recovery from hospital waste streams, novel concepts of MBRs and their applications are rapidly evolved through hybridizing novel membranes (non hydrophilic ultrafiltration/microfiltration) into the MBR units (hybrid MBRs) or the MBR as a pretreatment step and integrating other membrane processes as subsequent secondary purification step (integrated MBR-membrane systems). However, there is a lack of reviews on the latest advancement in MBR technologies for hospital wastewater treatment, and analysis on its major challenges and future trends. This review started with an overview of main pollutants in common hospital wastewater, followed by an understanding on the key performance indicators/criteria in MBR membranes (i.e., solute selectivity) and processes (e.g., fouling). Then, an in-depth analysis was provided into the recent development of hybrid MBR and integrated MBR-membrane system concepts, and applications correlated with wastewater sources, with a particular focus on hospital wastewaters. It is anticipated that this review will shed light on the knowledge gaps in the field, highlighting the potential contribution of hybrid MBRs and integrated MBR-membrane systems toward global epidemic prevention.

The opportunity of membrane technology for hydrogen purification in the power to hydrogen (P2H) roadmap

Hiep Thuan Lu, Wen Li, Ehsan Soroodan Miandoab, Shinji Kanehashi, Guoping Hu

《化学科学与工程前沿（英文）》 2021年第15卷第3期页码 464-482 doi: 10.1007/s11705-020-1983-0

摘要： The global energy market is in a transition towards low carbon fuel systems to ensure the sustainable development of our society and economy. This can be achieved by converting the surplus renewable energy into hydrogen gas. The injection of hydrogen (≤10% v/v) in the existing natural gas pipelines is demonstrated to have negligible effects on the pipelines and is a promising solution for hydrogen transportation and storage if the end-user purification technologies for hydrogen recovery from hydrogen enriched natural gas (HENG) are in place. In this review, promising membrane technologies for hydrogen separation is revisited and presented. Dense metallic membranes are highlighted with the ability of producing 99.9999999% (v/v) purity hydrogen product. However, high operating temperature (≥300 °C) incurs high energy penalty, thus, limits its application to hydrogen purification in the power to hydrogen roadmap. Polymeric membranes are a promising candidate for hydrogen separation with its commercial readiness. However, further investigation in the enhancement of H /CH selectivity is crucial to improve the separation performance. The potential impacts of impurities in HENG on membrane performance are also discussed. The research and development outlook are presented, highlighting the essence of upscaling the membrane separation processes and the integration of membrane technology with pressure swing adsorption technology.

Hongqi Wang, Ruhan Jiang, Dekang Kong, Zili Liu, Xiaoxiong Wu, Jie Xu, Yi Li

《环境科学与工程前沿（英文）》 2020年第14卷第1期 doi: 10.1007/s11783-019-1188-2

摘要： Explaintheadsorption, uptake and transmembrane transport of PAHs by bacteria. Analyze functional regulation of membrane proteins inthe transmembrane transport. Proteomics technology such as iTRAQ labeling was used to access expressed proteins. Single cell analysis technology wereused to study the morphological structure. In recent years, increasing research has been conducted on transmembrane transport processes and the mechanisms behind the microbial breakdown of polycyclic aromatic hydrocarbons (PAHs), including the role of membrane proteins in transmembrane transport and the mode of transmission. This article explains the adsorption, uptake and transmembrane transport of PAHs by bacteria, the regulation of membrane protein function during the transmembrane transport. There are three different regulation mechanisms for uptake, depending on the state and size of the oil droplets relative to the size of the microbial cells, which are (i) direct adhesion, (ii) emulsification and pseudosolubilization, and (iii) interfacial uptake. Furthermore, two main transmembrane transport modes are introduced, which are (i) active transport and (ii) passive uptake and active efflux mechanism. Meanwhile, introduce the proteomics and single cell analysis technology used to address these areas of research, such as Isobaric tags for relative and absolute quantitation (iTRAQ) technology and Nano Secondary ion mass spectrometry (Nano-SIMS). Additionally, analyze the changes in morphology and structure and the characteristics of microbial cell membranes in the process of transmembrane transport. Finally, recognize the microscopic mechanism of PAHs biodegradation in terms of cell and membrane proteins are of great theoretical and practical significance for understanding the factors that influence the efficient degradation of PAHs contaminants in soil and for remediating the PAHs contamination in this area with biotechnology.
