Abstract
A method for dispersing a water-soluble polymer includes: metering and prewetting polymer with primary water; grinding and draining of the dispersed polymer in a chamber comprising a rotor and a stator; and providing a ring with perforations fed by a secondary water circuit on all or part of the periphery of the chamber for spraying of pressurized water on the blades of the stator.
