WEMCO® DEPURATOR units use mechanically induced gas flotation (IGF) to remove oil and solids from produced water. After the produced water enters the DEPURATOR unit, motor-driven rotors induce a recirculating flow of air or blanket gas into the mixture. This disperses small bubbles throughout the tank volume, and oil droplets and solids are ...

For decades WEMCO flotation cells (there are 40,000 machines globally) have consistently delivered at the highest level when it comes …
Increase your recovery of viable product. As a crucial first step in the separation process, adequate attrition scrubbing removes surface films, coatings, or slimes to improve mineral values. By effectively scouring unwanted contaminants, impurities, and pollutants, the WEMCO® Attrition Scrubber plays a crucial role in product quality and ...
The basic module of the WEMCO 1+1 Inert Gas flotation system is a cell consisting of a single tank and mechanism. Several cells are bolted together to form a flotation process with feed, connection and discharge boxes as required. Pulp level in the tanks is controlled by automatically operated dart valves in the connection and discharge boxes.
There are more than 40,000 WEMCO flotation cells installed at mining operations across the globe, and the WEMCO II builds upon this success, incorporating improvements to the WEMCO rotor and stator/hood to lower power consumption, while increasing air flow and slurry pumping. The results are better hydrodynamics and circulation, improved ...
