Abstract
Methods for removing suspended particles from a solution are disclosed. These methods generally comprise adding to the solution to be treated an effective amount of a composition comprising a Mannich derivatized polyether. The polyether is generally described as the condensation polymer of Mannich derivatized bisphenol and a difunctional monomer. The methods have broad application in a wide variety of industries and are effective in removal of all types of suspended particles even when numerous types of particles are contained within the same solution.
