Abstract: A device and a process for making aqueous treatment fluids for recovering crude oil from subterranean, oil-bearing formations, comprising water-soluble polymers, preferably polyacrylamides, by firstly diluting an aqueous polymer concentrate comprising 3.5 to 10 wt. % of water-soluble polymer with an aqueous base fluid to a concentration of 0.01 to 2 wt. % of the water-soluble polymer. And secondly, dosing the diluted aqueous polymer concentrate into a blender or a polymer injection unit to obtain an aqueous treatment fluid. The aqueous treatment fluids obtained may be used as fracturing fluids or as enhance oil recovery fluids, among others. Furthermore, a new aqueous polyacrylamide concentrate—and its preparation process—, which may be used as starting material for making aqueous treatment fluids. The new aqueous polyacrylamide concentrate comprises at least water, polyacrylamide, a salt and a polyol or a surfactant.
