Modified dendrimer-based cationic flocculation has good dehydration performance.

Using DMC (methacryloyloxyethyl trimethylammonium chloride) to modify end groups of dendrimers (CYD-WD040/CYD-WD094/CYD-WD202) to obtain cationic dendrimer, used in dehydration areas, the results showed that: dendrimers have obvious flocculation and dehydration effect, especially the modified dendrimer has better result. Floc diameter is 6 times than the conventional flocculants, sedimentation time is only 36% of conventional flocculants, filter cake moisture content lower than conventional flocculants by 10%.
