Tube Skimmer Removes 104,000 Gallons of Oil from Wastewater Annually at Potato Chip Plant

Oil skimmer reduces cost, increases performance and decreases material waste

Potato-ChipsFood manufacturers
are tasked with managing oil in the wastewater from their manufacturing processes on an ongoing basis.

Recently, a privately-held snack food manufacturer that produces potato chips established a goal to increase
chip production by 20 percent. However, increasing production also meant increasing the amount of cooking
oil discharged into the wastewater from washing the fryers used to cook the chips. As one of the largest
water consumers within its municipality—discharging an average of 180,000 gallons per day—the potato chip
plant needed to cost-effectively and efficiently remove the cooking oil from its wastewater to remain
compliant with the municipality’s wastewater regulations.

Challenge: The plant’s 4-foot diameter wastewater pool is crowded with pipes and other
equipment—limiting space for adding any new equipment.

Solution: A custom-engineered oil
removal solution that included a tube-type oil skimmer was needed to fit the wastewater pool’s tight space.

Results: Oil Skimmers, Inc.’s Model 6V oil skimmer was successfully
implemented and effectively removes 2,000 gallons of oil per week from the facility’s wastewater pool. That
means, each year, more than 104,000 gallons of oil is collected. By installing a tube-type oil skimmer, the potato chip manufacturer is
able to skim oil from its wastewater 24 hours per day, seven days per week.

“We would recommend that anyone experiencing oil issues consider an oil skimmer from Oil Skimmers Inc.,” the
company’s wastewater treatment facilitator said. “For a relatively small investment, our operations have
been improved dramatically.”

Below are a few key areas in which the Model 6V oil skimmer has improved the plant’s operations:

  • Cost savings: The skimmed wastewater now requires less treatment before it enters the
    municipal system, reducing the amount of energy, labor and chemicals needed to process the effluent.
    Also, since installing the skimmer, the facility’s wastewater pool now produces less sludge—allowing the
    plant to save on hauling costs for sludge removal since it now uses the service less frequently.

  • Improved asset performance: The plant’s dissolved air floatation system is working more
    efficiently. “The filter press performance has increased, requiring less operator time cleaning the
    press,” said the company’s wastewater treatment facilitator. Additionally, loading on bioreactors where
    the water is treated has been greatly reduced, further improving efficiency.

  • Decreased material waste: The manufacturer has found a market for the discarded oil in
    companies that make bio-fuels, thereby keeping about 8,000 gallons of discarded oil out of landfills
    each month.
