Abstract
A system for mixing dry powder and water having a non-pressurized make-up reservoir (10). The make-up water is transferred by a booster pump (14) through a transfer pipe (20) at a predetermined flow rate and pressure for operation of a dry powder eductor (26) fed through powder hopper (28). The educted powder is instantly wetted through an area causing a high shear environment (25). A solution mix tank (32) is placed within the reservoir tank (10) having a turbine mixer (40) for maintaining the polymer solution in a uniform state. The mixed solution is maintained at a predetermined level and is available for transfer through discharge port (50) in batch, upon demand.
