PAM was used to improve the speed of solid-liquid separation, so that the particles settled quickly and the supernatant became clear. It was obviously that the selection of appropriate PAM products played a very important role in the effective solid-liquid separation to reduce the operation cost. 2. Type of Polyacrylamide 2.1. Anionic PAM
