Turning Waste Frying Oil into Recoverable Value at Golden West Foods Company
Oil Skimming Technology That Improved Wastewater Performance While Reducing Maintenance Demands
Food processing facilities generate large volumes of wastewater that often contain significant amounts of fats, oils, and grease (FOG). When not properly managed, these contaminants can clog piping systems, increase treatment costs, and reduce overall wastewater handling efficiency.
At a Golden West Foods production facility, wastewater streams carrying frying oil and organic residues created ongoing operational and maintenance challenges. To address this, the facility implemented an oil removal solution from Abanaki Corporation designed to continuously separate and recover floating oils from process water systems.
The result was improved wastewater flow reliability, reduced system blockages, and the ability to recover usable oil for reuse or resale.

The Challenge: High-Volume Frying Oil in Wastewater Streams
In food production environments, especially those involving frying and batter-coated products, oil contamination in wastewater is a persistent issue. At the Golden West Foods facility, oil entered the wastewater system through routine production and sanitation activities, including:
- Frying operations and product coating wash-off
- Sanitary washdowns of processing equipment and floors
- Drainage from production lines handling breaded food products
- Separation overflow from intermediate holding systems
Over time, these inputs created a high concentration of floating oil in wastewater handling areas.
This led to several operational issues:
- Frequent buildup of grease and oil in piping and bends
- Reduced efficiency in wastewater transfer and equalization systems
- Increased maintenance requirements for cleaning and unclogging lines
- Higher operating costs associated with wastewater treatment
- Loss of potentially recoverable oil product
- Risk of overflow and process interruptions during peak production
The facility needed a continuous, low-maintenance method to remove surface oil while also improving overall system reliability.
The Solution: Installing an Abanaki Belt Oil Skimming System and Operational Benefits
To address ongoing oil contamination, Golden West Foods installed a belt oil skimming system from Abanaki Corporation designed to continuously remove floating oils from wastewater streams and collection tanks.
The system was selected for its ability to operate continuously in high-load wastewater environments and separate oil without excessive water carryover, improving both recovery value and system performance.
Once installed at key separation and holding points, the skimmer continuously removed surface oil from wastewater before it could accumulate or enter downstream piping.
This implementation delivered several operational benefits:
- Continuous removal of frying oil from wastewater streams reduced buildup in piping and equalization tanks
- Improved wastewater flow reliability minimized clogging in bends and transfer lines
- Reduced maintenance and cleaning frequency lowered labor demands for system upkeep
- Higher recovery efficiency of usable oil allowed captured oil to be reclaimed and reused or sold
- Improved performance of wastewater treatment processes by reducing FOG loading
- More stable operation during high-production periods reduced risk of overflow and system interruptions
The system’s simple belt-based design enabled consistent operation with minimal oversight, even under continuous production conditions.
Why Food Processing Facilities Use Belt Oil Skimmers
Food manufacturing and processing plants use belt oil skimming systems to:
- Control fats, oils, and grease (FOG) in wastewater systems
- Prevent pipe and equipment fouling
- Reduce wastewater treatment costs
- Recover usable oil byproducts
- Improve overall sanitation system reliability

Frequently Asked Questions
Why is oil a problem in food processing wastewater?
Oil can accumulate in piping and tanks, causing blockages, reducing flow efficiency, and increasing treatment costs.
Can recovered frying oil be reused?
Yes. In many cases, recovered oil can be collected and repurposed for industrial or commercial applications depending on quality and regulations.
Are belt oil skimmers suitable for high-volume food plants?
Yes. They are commonly used in continuous production environments due to their reliability and low maintenance requirements.
Do oil skimmers require frequent maintenance?
No. They are designed for continuous operation with only occasional service, such as belt replacement.
