Abstract : A system including an apparatus and method for dissolving powder into a liquid is disclosed. The apparatus includes a powder supply device which supplies powder, such as a water soluble resin polymer which is to be dissolved in water, to a powder and air mixing chamber. Pressurized air, at a low pressure, is mixed with the powder to provide an air and powder mixture. The pressurized air and powder mixture is supplied to the bottom of a powder and liquid mixing tank, below the surface of the liquid. A mechanical mixer gently agitates the liquid while the low pressure powder and air mixture is supplied to the mixing tank, to assure generally uniform distribution and dissolving of the powder in the liquid.
