WEMCO® DEPURATOR* units use mechanically induced gas flotation (IGF) to remove oil and solids from produced water. After the produced water enters the depurator, motordriven 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 carried to the surface in a rising gas froth, where they ...
