Industrial Wastewater Skimmers for Steel Mills
Removing Grease from Steel Manufacturing Wastewater:
Oil Skimmer is Lowest-Cost Method
Abanaki offers industrial wastewater skimmers specially designed for steel mills
where plant maintenance engineers are looking for the lowest cost, most
reliable method of removing greases and heavy oils from the steel-mill scale
pit. Abanaki oil skimmers use the difference in specific gravity and surface
tension between grease and water, allowing the belt to attract grease and
oil as the belt passes through the surface of the water. The simple
belt-and-motor approach is proven to operate unattended and reliably for
decades with little maintenance.
To avoid fines from government and municipal sewer districts, steel mills
must limit the amount of grease in wastewater discharged into the
environment. The Grease Grabber® oil and grease
skimmer provides a continuously operating belt and wiper that can remove up
to 160 gallons per hour of heavy greases and oils. Depending on the
characteristics of the liquid, the oil/grease skimmer is capable of reducing
grease content to fewer than five parts-per-million in water. Reclaimed
grease and oil can be re-used or used as furnace fuel, avoiding sucker truck
Using a double drive roller and tail pulley system, the grease skimmer
belt runs through wastewater to pick up grease and heavy oil from the
surface. The belt travels over the head pulley and then passes through
tandem wiper blades, from which oil is scraped off both sides and
discharged. A heated hopper keeps grease flowing in cold outdoor
The tail pulley features flanges that allow the pulley to roll freely on
the inside of the belt without becoming dislodged in turbulent applications.
No bearings are needed; the unit does not need to be fastened to the tank.
An optional tether and cage assembly is offered to prevent the tail pulley
from being dislodged. The Grease Grabber oil skimmer can be used in pits
with depths as shallow as one foot or as deep as 100 feet.
If grease mats on the water surface, an optional MatBuster™ agitator may
