摘要： A method for flocculating suspended solids from an aqueous system containing water and said suspended solids comprising adding to said aqueous system an effective amount of a flocculating agent, wherein said flocculating agent is a pourable non-aqueous, polymer composition containing less than about 5%, water and greater than 60%, polymer solids. The polymer of the instant polymer compositions may be anionic, non-ionic, cationic or amphoteric. Related compositions are also claimed.
