Aquaculture is an important industry that provides a significant portion of the world's seafood supply. However, it also generates large amounts of wastewater containing various pollutants. To mitigate the environmental impact, effective treatment methods are required.

Polyacrylamide (PAM) is a kind of linear organic polymer, but also a kind of polymer water treatment flocculant products, can adsorption suspended particles in the water, the link between the particles bridge, so that the fine particles to form a relatively large flocculation, and accelerate the speed of precipitation.

This process is called flocculation, because of its good flocculation effect PAM as a flocculant of water treatment and is widely used in sewage treatment. Especially in aquaculture, there are very high requirements for water quality and better treatment of sewage.
