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 membrane processes and former research conclusions. Some suggestion was also given to facilitate further study in this field.
