 Skip Hogue is
maintenance manager at St Joe Container Corporation, a paper mill and
converter in College Park, GA that produces about 100 tons of corrugated boxes each day.
Hogue noticed excessive oil in
the wastewater discharge from boxboard operations. This oil comes from the rolls and
bearings on the corrugating machines, and ends up in the plant's drainage system. Drainage
water empties into a three-stage collection pit that has a system of three weirs for
skimming and decanting the fluid before water is allowed to enter the city's sewer lines.
An oil skimmer in the second stage pit wasn't performing satisfactorily and oil was ending
up in discharge water.
It wasn't long before Hogue
replaced the old skimmer with Abanaki's Oil Grabber® Model 4. |

Hogue's skimmed
oil is picked up by an oil recycling company. The company's policy is that they do not
charge for pick up if there isn't a lot of sludge in the oil that requires pretreatment
before processing. Hogue says, "That could be a problem... because cardboard scrap
and starch from the production process ends up in the plant's drainage water. So we
purchased the Abanaki unit with their optional decanter, which has a screen to remove
sludge and provides a final separation stage... the unit has been running for months
without attention."
Hogue adds, "Since
installing the Abanaki unit, we haven't had to pay to have our waste oil hauled away, and
College Park sewage treatment officials are happy with the quality of our water
discharge." |
