Abstract
A method and apparatus for rapidly dispersing particles of dry, water soluble polymer into water wherein air, water and said polymer particles are introduced to a chamber for thorough contact of the polymer with the water to form a mixture of aqueous polymer dispersion and entrained air. The mixture is immediately subjected to shear forces to separate any agglomerated particles into individual particles, and to prevent further agglomeration.
