Abstract:
Lysine-based polymers, particularly copolymers of lysine and maleic acid, are useful as coagulants for clarification of wastewaters, including produced waters from oils sands mining operations. They can be advantageously used in combination with commercial coagulants, and in combination with flocculants. Such combinations may include dry blends. Also described are methods of preparation of lysine homopolymers and copolymers.
