Product Sheet WEMCO SILVER BAND
The WEMCO SILVER BAND separator provides efficient bulk separation of oil and solid contaminants from liquid streams with lower system costs and maintenance and increased uptime.
Mechanically induced gas flotation unit for secondary recovery of oil and solids from produced water
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 carried to the surface in a rising gas froth, where they are recovered by skimming.
Applications include onshore and offshore (fixed and floating) oil production, refinery and petrochemical wastewater, and metal casting and primary metal industry wastewater processing. Though the original IGF design is still the standard for many applications, the new pressurized version—available in two- to five-cell designs—provides a distinct advantage for the oil and gas industry.
