Wastewater purification via impeller fluidized microemulsion liquid membranes
The Impeller Fluidizer uses impeller generated fluid flows to concentrate a dense slurry of fine particles. The application of the fluidizer to wastewater treatment using emulsion liquid membranes extends the Impeller Fluidizer's scope to include liquid-liquid interactions. Liquid-liquid fluidization requires two immiscible phases and is otherwise analogous to solid-liquid contacting. The project develops a suitable liquid membrane which could operate in an Impeller Fluidizer while separating contaminants from an aqueous stream. Experiments were conducted to determine: (1) the effect of shear rate and fluidizer configuration on leakage stability and fluidization of emulsion liquid membranes; (2) the kinetics of single contaminant removal from aqueous solution; and (3) the feasibility of multiple contaminant separation in a staged series of Impeller Fluidizers. The separation technique will benefit not only wastewater treatment industries, but can also be applied to biochemical recovery, hydrometallurgy, and commodity chemical recovery. Utilizing simple, inexpensive equipment, the technology will yield high mass transfer and high flow rates.
