Atmospheric air is used to disperse the polymer fed into the chamber by a suitable feeder and to generate air/water turbulence in the wetting chamber in which the polymer is wetted. Suction draws the metered polymer into the wetting chamber and increases the downward velocity of the polymer as it enters the turbulent section of the wetting chamber. When wetted, the polymer is transferred to a mixing tank for aging. It is then ready for use in various industries. | |
