Abstract
A method for treating aqueous solutions, wherein a filtrate material is manufactured to have a polymer with ion exchange properties adhered to the surface or impregnated within a porous, granular particle such that the resultant structure does not result in any agglomeration or binding of the granular particles, thereby retaining the maximum surface area of the particle for reacting with metal impurities in solution. A filtrate material comprised of a porous granulated particle and an ion exchange polymer. A method of treating aqueous solutions by passing an aqueous solution through the filtrate material to remove metal impurities in the solution. A method of regenerating the filtrate material that is saturated with metal impurities.
