Abstract: Development and application of cationic organic flocculants are introduced in this paper. Modified cationic polyacrylamide flocculants, dicyandiamide-formaldehyde flocculants and modified cationic high polymer flocculants from natural high polymer are reviewed. The prospect of application of cationic organic flocculants in China is discussed.
