Mixer-Settler Systems for Every Scale
No Interstage Pumps. No Unnecessary Complexity. Just SX That Works.
From laboratory pilot units to full commercial operations, our mixer-settler systems are tailored to meet the unique needs of your project.
Key Design Advantage
QPEC mixer-settlers utilize impellers in the mix tanks specifically engineered to both advance (pump) and thoroughly mix the incoming feed streams — aqueous, organic, and recycle — at the mixer eye.
This eliminates the need for interstage pumps, significantly simplifying system control and operation. Only external feed pumps (for aqueous and organic feeds) and their associated tanks, flowmeters, and valves are required.
All QPEC mixer-settlers are designed with equal liquid levels in both the mixer and settler, allowing for straightforward startup and shutdown with no need for surge tanks to handle backflow.
