“…Based on the boundary layer theory, the theoretical steady aeration intensity was 172 L h -1 in a precoated dynamic membrane bioreactor (PDMBR) [48]. Under this aeration intensity, the PDMBR showed high stability and filtration performance, with a COD removal rate of 97.5 % and NH 3 -N removal rate of 76.1 %.…”

Applications of dynamic membrane (DM) filtration and factors affecting formation, filtration, and cleaning are introduced. DMs have been studied extensively for wastewater treatment in recent years. DM formation methods and mechanisms are explained. Effects of supporting material, deposited material, formation pressure, and pH on the DM formation are discussed in detail. The impacts of operation pressure, aeration intensity, cross-flow velocity, temperature, and other parameters on the DM filtration process are evaluated and different DM cleaning strategies are reviewed. The applications of DMs to treatments of municipal wastewater, surface water, oily water, industrial wastewater, sludge, and microalgae harvesting are discussed. Finally, possible future research directions and some guidelines for DM technology are given.

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 3 $d -1 ) are provided, and the growth trend of total treatment capacity as well as its driving force is analyzed.
