Abstract: The present invention generally relates to a method for separating solids from liquid in a slurry comprising solids and a liquid (e.g., an aqueous solution). More specifically, the method comprises contacting an effective amount of a high molecular weight polymeric flocculant with the slurry in a tanker truck or as the slurry is flowing to the truck, allowing the solids to settle during a settling time whereby the solids settle to the bottom of the tanker truck, and the liquid is removed from the tanker truck at a level above the settled solids. The high molecular weight polymeric flocculant can comprise repeat units derived from a cationic monomer, an anionic monomer, a nonionic monomer, or a combination thereof.
