In today’s industrial landscape, managing oil contamination isn’t just about compliance — it’s about efficiency, safety, and environmental responsibility. One of the most widely used tools for oil removal is the oil skimmer. But what exactly is it, how does it work, and why is it so critical in a variety of industries?

We’ll explore everything you need to know about oil skimmers: how they function, where they’re used, the different types available, and how to choose the right one for your needs.

What Is an Oil Skimmer?

An oil skimmer is a mechanical device designed to remove floating oil from the surface of water or other liquids. Because oil is lighter than water, it rises to the surface — and that’s where skimmers do their job.

Whether in an industrial sump, a coolant tank, or an open body of water after a spill, oil skimmers help separate and recover this surface oil for reuse or disposal. This process not only keeps systems clean but also prevents environmental contamination and regulatory violations.

Why Use an Oil Skimmer?

Oil skimmers serve multiple purposes across industries. Here are some of the key benefits:

✅ Environmental Compliance

Environmental regulations, such as those enforced by the EPA or local authorities, often require facilities to manage and minimize oil discharge. Oil skimmers help meet these standards by physically removing oil before it can enter sewer systems or natural waterways.

✅ Cost Savings

By skimming oil from liquids like coolant or wash water, facilities can often extend the life of their fluids, reduce maintenance costs, and minimize the need for chemical treatments or absorbent materials.

✅ Improved Equipment Lifespan

Excess oil in machine coolants or cleaning solutions can lead to fouling, corrosion, and microbial growth. Regular removal of oil helps maintain clean fluids, which in turn reduces wear and tear on equipment and extends its lifespan.

✅ Safety

Oil buildup in sumps and tanks can create slip hazards, fire risks, or interfere with other operations. Skimming the oil away helps maintain a safer work environment.

How Do Oil Skimmers Work?

The fundamental principle is simple: oil floats on water. Skimmers are designed to capture and collect this floating oil using various materials and mechanisms that attract or direct the oil into a collection vessel.

The oil can then be:

• Pumped into a waste tank
• Recycled back into the system (in some applications)
• Disposed of in accordance with environmental regulations

Let’s look at some of the most common types of oil skimmers and how they function.

Types of Oil Skimmers

1. Belt Oil Skimmers

Belt skimmers use a continuous loop of oil-attracting (oleophilic) material — often polyurethane, stainless steel, or elastomer — that moves through the liquid surface. As the belt picks up oil, it passes through a set of scrapers or wipers that remove the oil and deposit it into a collection container.

Best for: Coolant tanks, machining centers, and parts washers.

2. Tube Oil Skimmers

These systems use a floating tube made of oil-attracting material. The tube snakes across the liquid surface, collecting oil, which is then removed by a drive system and scraped off into a container.

Best for: Irregularly shaped tanks or areas with floating debris.

3. Disk Oil Skimmers

Disk skimmers use a rotating disk partially submerged in the liquid. Oil adheres to the disk’s surface and is removed by wipers as it spins.

Best for: Shallow tanks or open-top containers with limited surface area.

4. Drum or Barrel Skimmers

These are similar to disk skimmers but use a rotating drum or barrel instead of a flat disk. They typically offer a higher oil removal capacity.

Best for: Industrial wastewater treatment, large tanks.

5. Weir Skimmers

A weir skimmer uses a floating intake that allows surface oil to flow over a weir (a barrier or lip) into a collection chamber. These skimmers rely on gravity and are useful when large volumes of oil need to be collected quickly.

Best for: Oil spill response, stormwater basins, and retention ponds.

Common Applications of Oil Skimmers

Oil skimmers are used across a wide range of industries and environmental settings, including:

• Metalworking and machining: Removing tramp oil from coolant systems
• Automotive manufacturing: Cleaning wash water and treating process fluids
• Food processing: Managing animal fats or vegetable oils in wastewater
• Marine and shipping: Cleaning bilge water and responding to oil spills
• Environmental cleanup: Skimming oil from lakes, rivers, and coastal areas
• Power plants and utilities: Treating wastewater from turbine and generator operations

How to Choose the Right Oil Skimmer

Selecting the correct oil skimmer involves several key considerations:

Consulting with an expert or supplier can help you choose the right model based on your specific operating conditions.

Oil skimmers may seem like a small component in a large industrial process, but their impact is significant. They reduce operational costs, extend equipment life, enhance safety, and ensure environmental compliance — all by doing one simple thing very effectively: removing oil from liquid surfaces.

Whether you're running a small machine shop or managing a large-scale facility, integrating the right oil skimmer can lead to cleaner systems, more efficient processes, and a healthier environment.

Oil skimmers play a crucial role as unsung heroes in the ongoing fight against oil contamination. Their significance transcends mere functionality, as they serve as guardians of environmental integrity and industrial efficiency alike. Whether tasked with preserving the purity of coolant systems to prolong the lifespan of vital industrial tools or ensuring that wastewater remains free from the deleterious effects of oil discharge into the environment, a well-operating skimmer emerges as an invaluable asset. In recognition of their indispensable role, here are 11 invaluable tips aimed at maximizing the efficiency of oil removal from both water and coolant systems:

1. Level Up: Ensure that the skimmer is mounted perfectly level. This is particularly crucial for skimmers equipped with free-hanging belts, as proper alignment guarantees smooth tracking over the pulleys, optimizing performance and longevity.
   
   
2. Wipe Wisely: Strike the right balance when positioning the wiper blades—not too tight, but with gentle contact against the belt. Over-tightened blades accelerate wear and tear, while insufficient tension compromises oil recovery efficiency, leaving behind valuable residue.
   
   
3. Time It Right: Operating the unit only when oil is present minimizes the risk of inadvertently collecting coolant or water. Consider utilizing a timer for automated operation, enhancing efficiency and reducing energy consumption by running the skimmer precisely when needed.
   
   
4. Calm Waters: To maximize effectiveness, deploy the skimmer during periods of minimal turbulence. Operating it during quiet times allows the oil to naturally rise to the surface, facilitating easier removal and ensuring thorough cleanup.
   
   
5. Be Prepared: Keep spare belts and wiper blades readily available to swiftly address any maintenance needs and minimize downtime. This proactive approach ensures uninterrupted operation and optimal performance.
   
   
6. Length Matters: Select a belt of sufficient length to ensure that the tail pulley remains submerged even at the lowest liquid levels. This strategic choice maximizes oil collection efficiency across varying conditions, guaranteeing thorough cleanup without compromise.
   
   
7. Size Up: Properly match the skimmer size to the dimensions of the tank. Opt for a skimmer that optimizes oil removal relative to the tank's size, ensuring efficient cleanup without unnecessary excess capacity or inefficiency.
   
   
8. Concentration Matters: When running the skimmer in scenarios with minimal oil presence, employ an oil concentrator to prevent the inadvertent removal of coolant and water. This targeted approach conserves resources and maximizes efficiency, ensuring optimal performance even in challenging conditions.
   
   
9. Belt Selection: Carefully select the appropriate belt for the application to enhance skimmer longevity and efficiency. Choosing the right belt minimizes wear and tear while maximizing oil capture capabilities, ensuring sustained performance over time.
   
   
10. Strategic Positioning: Position the skimmer strategically, with the downstroke of the belt targeting the bulk of the floating oil. Ensure that the skimmer is positioned at least 2 feet away from walls or tank sides to avoid interference and optimize oil removal efficiency.

Removing oil from water is a crucial step in many processes across numerous industries. From extending tool life to staying in compliance with government agencies, oil skimmers provide a cost-effective solution to removing oil from water or coolant.

Companies always look for effective ways to remove oil from water or coolant. Here are few more easy tips to skim oil from water or coolant.

If the skimmer must be run when little or no oil is present, use an oil concentrator

Under most operating conditions, skimmers pick up oil with only small traces of water. However, as surface oil is reduced to a thin layer (1/16 inch thick or less), more water (or coolant) may be picked up along with the oil. When used in tandem with an oil skimmer, the oil concentrator solves this problem by providing final phase separation. The result of this is optimal levels of water or coolant becoming available for recycling, and virtually water-free oil for is collected by the skimmer.

Choose the right belt for your application

Take the time to study which belt best fits your application – it will maximize the life of the skimmer belt and optimize the efficiency of skimmer. This applies to both length of the belt and the material of which it is constructed. As mentioned previously, choose a belt length that assures contact with the liquid at its lowest level. Belt materials are wide ranging and need to be selected based on variables such as the type of oil being collected, the liquid media that the oil is being collected from, and whether the skimmer is being used in an interior or exterior application. Any good skimmer dealer should be able to offer assistance when it comes to belt selection. Testing different belt materials prior to final selection is always a wise course of action.

Choose the optimal location for the skimmer to be mounted

Power availability and accessibility for routine maintenance need to be considered when selecting the location of the unit. Once that locale has been narrowed down, the skimmer should be mounted so that the down stroke of the belt is facing the bulk of the floating oil and is not within 2 feet of a wall or a tank side. This will ensure that the belt will be positioned to attract the maximum amount of oil, without allowing any dead zones where oil can be allowed to become stagnant.

Oil skimmers are simple, dependable and effective tools for removing oil, grease and other hydrocarbons from water and coolants. Often, an oil skimmer by itself can achieve the desired level of water purity.

In more demanding situations, oil skimming is a cost-effective means of removing most of the oil before using more complicated and costly treatments such as coalescers, membrane filters and chemical processes.

As with any piece of industrial equipment, there are guidelines that should be followed to promote optimal efficiency, as well as a long, trouble free operational life. Let’s take a look at a few tips that will help you get the most out your oil skimmer.

A skimmer is most effective when there is no turbulence in the media

Skimmers rely on the differences in specific gravities between oil and coolant or water that causes oil to float on top of water. In applications where turbulence is present, the process of oil rising to the top will be prolonged, with some oil remaining below the water until conditions allow gravity to ultimately prevail. Operating the skimmer predominantly during quiet times will give oil the chance to rise to surface and allow the unit to operate more effectively.

Keep a spare belt and wiper blades on hand

Being prepared for the unexpected is always good practice. While blades and belt are typically very durable and trouble free, you never want to be in a situation where the skimmer must be taken out of service until a new belt or wiper blades arrive from halfway across the country.

Choose a belt that is long enough so that the tail pulley is submerged when the liquid level is at its lowest point

Water and coolant levels can vary over time. Therefore, the skimmer needs to be capable of collecting oil when the levels are at their lowest. Taking the time to correctly size the belt prior to purchasing the unit will save a lot of headaches down the road.

Properly size the skimmer to the size of tank

Skimmers operate by breaking surface tension which allows oil to be attracted to the belt. If a unit is undersized, it will not have the strength to disrupt the surface tension of the liquid, meaning that oil will never make it to the belt. Sizing of the unit should always be based on the overall area of the tank, not the volume of oil that is expected in the tank. This will guarantee that the skimmer will be capable of overcoming the surface tension that is present for the given tank area.

Oil skimmers are tremendously versatile, especially when the wide range of venues where they are called upon to operate is considered. Basically, anywhere oil and water have the potential to mix presents an opportunity for a skimmer to be put to good use, keeping oil out of water or coolant so that it can be recycled, re-used, or safely discharged.

The applications where these unsung workhorses perform are numerous, with skimmers being called upon to keep oil out of the places it does not belong, such as machinery coolant, bilge tanks, and wastewater that is discharged from parking garages. While there are differences in design from one skimmer vendor to the next or variations based upon their application, all skimmers ultimately rely on the differences in specific gravity and surface tension in oil and water to allow them to attract and capture oil. A rotating disc or belt is then used to collect the oil, where it can then be recycled or reused.

Make sure the skimmer is mounted level

It is strongly recommended to take the time during the initial installation to check that the skimmer is mounted and fastened securely in an orientation that is level. This is especially critical for skimmers with free-hanging belts to ensure proper tracking over the pulleys. This will promote better performance and reduce premature wear on the belt, wipers, pulleys, and motor.

Proper positioning of wiper blades is essential

Maintaining the proper amount of tension on the wiper blades is key to optimizing skimmer performance. Striking a balance that allows the blades to contact the belt in a manner that allows them to remove the majority, if not all of the oil from the belt is ideal. Over tightened wiper blades will cause premature wear on blades. Under-tightening leads to poor recovery results, as the oil collected by the belt is not fully removed as the belt passes over the wipers.

Run the skimmer when oil is present

While this may seem like a rather obvious point, running a skimmer constantly may actually be counterproductive, because it increases the likelihood that coolant or water will be picked up by the belt. A timer or an oil in water sensor can be employed to optimize skimmer operating efficiency by controlling the times when the unit is running.
