Abstract: Disclosed herein are the water clarification compositions and method of using the disclosed water clarification compositions for clarifying a water system or waste water source. Specifically, the disclosed compositions comprise and methods use multiple charged cationic or anionic compounds that are derived from polyamines through an aza-Michael addition with an activated olefin having an ionic group. The disclosed water clarification methods or compositions are found to be more effective than those methods or compositions including commonly used single quaternary compounds for reducing turbidity in water systems or waste water sources.
