ABSTRACT

Introduction

Self-forming dynamic membrane (SFDM) technology has been gaining significant interest due to its potential advantages, notably lower capital and operational cost and easier fouling control, over conventional membranes used in membrane bioreactors. SFDM technology utilizes inexpensive support material integrated with a dynamic membrane (DM) made of suspended solids and biomass to provide high effluent quality.

Objectives

This paper aims to bridge the gap between the previous reviews and the current studies to provide a comprehensive review on SFDM applications to both aerobic and anaerobic bioreactors.

Literature review

The historical development of DMs since the 1960s up to the present is presented. Specific attention was given to DM formation mechanisms, deposition time, impacts of design, and operational factors (mesh characteristics and sludge properties) on DM formation and performances and on DM-based integrated systems.

用于废水处理的自成型动力膜

摘要

介绍

与膜生物反应器中使用的传统膜相比，自形成动态膜 (SFDM) 技术因其潜在优势而备受关注，尤其是较低的资本和运营成本以及更容易控制结垢。SFDM 技术利用廉价的支撑材料与由悬浮固体和生物质制成的动态膜 (DM) 相结合，以提供高质量的出水。

目标

本文旨在弥合以前的评论和当前研究之间的差距，以提供关于 SFDM 在好氧和厌氧生物反应器中的应用的全面评论。

文献评论

介绍了 1960 年代至今 DM 的历史发展。特别关注 DM 的形成机制、沉积时间、设计的影响以及对 DM 形成和性能以及基于 DM 的集成系统的操作因素（网格特征和污泥性质）。
