Key Laboratory of Yangtze Water Environment of Ministry of Education, Tongji University, Shanghai 200092, China) Abstract: Algogenic organic matter (AOM) is released from algae cells. AOM could become a really significant pollutant when algae bloom. Membranes have emerged as a key means of water treatment with high efficiency and excellent effect. However, membrane fouling by AOM remains a critical factor limiting the efficiency of low pressure membrane treatment systems including microfiltration and ultrafiltration. This paper overviewed the components and categories of AOM, different mem- brane processes and former research conclusions. Some suggestion was also given to facilitate further study in this field.
