In the waste management industry, effective oil-water separation is crucial for environmental protection and regulatory compliance. One innovative solution gaining popularity is the Vertical Tube Coalescer (VTC), a technology that efficiently removes oil from wastewater. This article will delve into the workings of VTCs and highlight the benefits of AFL Industries, Inc.'s leading model.
What is a VTC?
A VTC is a type of oil-water separator that utilizes a unique coalescence process to remove free and emulsified oil from wastewater. This process relies on a series of vertical tubes filled with a coalescing media, which promotes the merging of small oil droplets into larger ones. These larger droplets then rise to the surface, where they are easily removed.

Scenario: A manufacturing plant produces wastewater containing 500 gallons of oil per day. They are currently using a traditional oil-water separator that removes only 80% of the oil. They are considering purchasing a VTC that has a 95% efficiency rating.
Task: Calculate the amount of oil that would be removed daily if the plant switched to the VTC.
Current oil removal: 500 gallons * 80% = 400 gallons Oil remaining: 500 gallons - 400 gallons = 100 gallons VTC oil removal: 500 gallons * 95% = 475 gallons Therefore, the VTC would remove 475 gallons of oil daily, significantly reducing the amount of oil discharged into the environment.
Gravity separation is a basic technique that relies on the density difference between oil and water. The wastewater is passed through a settling tank where the heavier water sinks to the bottom, while the lighter oil floats to the surface. This method is simple and cost-effective, but it is less effective for removing emulsified oil.
DAF uses fine air bubbles to attach to oil droplets, making them buoyant enough to rise to the surface. This method is efficient in removing both free and emulsified oils, but it requires specialized equipment and can be energy intensive.
Coalescence techniques promote the merging of small oil droplets into larger ones, making them easier to remove. This is achieved by passing wastewater through a coalescing media, such as hydrophobic fibers or membranes, which trap the oil droplets and encourage them to combine. Vertical Tube Coalescers (VTCs) are a type of coalescence technology.
Filtration uses porous media to physically remove oil droplets from the wastewater. This method can effectively remove suspended oil, but it may not be as efficient for emulsified oil.
Chemical treatment involves adding chemicals to break down the emulsion and separate the oil and water. This method can be effective but can also be expensive and generate hazardous waste.
