6 Types of Oil Skimmers | Belt, Rope, Mop & More | Abanaki

Posted by Tom Hobson on Jun 21, 2019 11:41:16 AM

For industrial oil skimming, there are six basic designs commonly used:

  1. Belt Skimmers
  2. Disk Skimmers
  3. Drum/Barrel Styles
  4. Mop Skimmers
  5. Tube Skimmers (Large and Mini)
  6. Floating Suction Skimmers

Belt Oil Skimmers

Belt-type oil skimmers use an endless belt of corrosion resistant steel or synthetic medium, which is lowered into the tank or vessel to be skimmed. The belt passes through resilient wiper blades where the oil is removed from both sides of the medium.

Belt machines provide a simple, dependable and cost-effective method for removing oil, grease and other hydrocarbons from water.


Disk Oil Skimmers

These oil skimmers rotate a disk-shaped medium through the liquid. Oil is wiped off and discharged into a collection container in a manner similar to belt oil skimmers. It is important to consider reach, the portion of the disk that actually gets immersed,

when looking at a disk oil skimmer. Less disk in the fluid means less oil removed. Obviously, fluctuating fluids can be a real problem for disk oil skimmers.


Drum/Barrel Styles

These are similar to the disk type, but use a rotating drum shaped medium. Compared to disk types, they are usually more rugged and have higher removal capacity. Depending on the design, these units can also be rendered ineffective by fluctuating fluid levels. Also, water pickup with this type of oil skimmer can be high.


Mop Oil Skimmers

These oil skimmers use an endless medium shaped like a rope and having mop-like tendrils that pick up the oil. As the medium leaves the liquid and enters the drive unit, it is pressed and wrung out with pinch rollers. For higher viscosity oils, the medium tends to mat down and lose effectiveness. A decant system is a must for these units, as water pickup can be very high. Also, replacement oil mops can be very expensive, so check prices on replacements before purchasing.


Tube Skimmers

Large Tube Skimmers

Tube oil skimmers use a floating plastic hose that snakes out over the surface of the liquid and is then drawn back through the drive unit where oil is removed. This design requires a relatively large amount of surface area for proper operation. This oil skimmer can skim from very shallow tanks. As a rule, the removal capacity is lower than belt, drum or mop type oil skimmers.

Mini Tube

Very similar to the large tube units, but use either a 3/16″ or a 5/16″ tube instead of 1″. The pickup rate varies from 1 quart/hour to 1.5 gph depending on the diameter of the tube. These tube skimmers are fairly compact, and can fit in tight spots. The better units will have the motor mounted underneath, to bring room required over the lip of the tank down to near zero. The 5/16″ diameter tube is preferable as it has a 1 gph removal capacity and enough stiffness to not drag on the housing and prematurely wipe off oil when being drawn into the unit.


Floating Suction Skimmers

These come in several forms, but all have a floating intake. They are most suitable for relatively thick layers of oil (1/4 inch or higher); otherwise, they tend to ingest large amounts of water. Some machines will actually emulsify oil due to churning as it passes through the suction pump. This type of oil skimmer requires a coalescing or at least a decanting unit to be at all effective. The standard drive on all units is an electric motor and gear reducer. Other drive types available.

Advantages of Using an Oil Skimmer in the Machining Industry

Posted by Tom Hobson on Nov 19, 2018 10:45:00 AM

Companies look for effective ways to remove oil from water or coolant to reduce costs and the liability of proper disposal. Another reason for removing the oil is a better work environment. Letting oil remain in the coolant tank allows anaerobic bacteria to grow. Anaerobic bacteria break down the components of coolant, causing it to need changing more frequently. Oil-laden coolant with a high anaerobic bacteria content has two other drawbacks as well. The first drawback is an unpleasant odor caused by the bacteria. The second drawback the smoke generated from the oil-laden coolant coming in contact with the operating cutting tool. One of the easiest ways to remove hydrocarbons from water or coolant is by using an oil skimmer. It is a low maintenance, easy to use tool for removing oil from water or coolant.

The use of an oil skimmer holds many benefits including:

Reduction of Disposal Costs: The cost of disposing oil laden coolant is more expensive than the disposing of oil.

Recycling Opportunities: In some instances, companies may be able to re-use the skimmed oil elsewhere or sell it for recycling, choosing to keep their part of the world cleaner.

Extend Coolant Life: Having oil free coolant can also extend its usefulness and effectiveness, reducing the expense on maintenance and coolant replacement.

Esthetic Benefits: Removing the oil from a machine coolant tank will cut down on the amount of smoke generated from the cutting tool coming into contact with oil laden coolant thereby creating a visibly cleaner workplace.

Extend Tool Life: Removing floating surface oils while aerating and refreshing coolant will extend tool life as well.

Avoid EPA Violations: Many machining and metal working shops turn to aqueous parts cleaning because of limits imposed by the EPA on the discharge of emissions and wastes.

Hygienic Benefits: Keeping coolant oxygenated and oil-free reduces the “rotten egg” odor and bacterial levels are lowered resulting in a cleaner work environment.

How Do I Remove Oil from Coolant or Water

Posted by Tom Hobson on Nov 14, 2018 10:15:00 AM

It is a common question asked every day by people in all fields of industry. Machine shops, steel mills, industrial manufacturers, and many others are faced with the problem of removing oils from coolants and wastewater on an everyday basis. They are faced with high disposal and maintenance costs. Some manufacturers are charged extreme amounts to have their contaminated water treated properly by their local water treatment facility.

Companies look for effective ways to remove oil from water or coolant to reduce costs and the liability of proper disposal. Another reason for removing the oil is a better work environment. Letting oil remain in the coolant tank allows anaerobic bacteria to grow. Anaerobic bacteria break down the components of coolant, causing it to need changing more frequently. Oil-laden coolant with a high anaerobic bacteria content has two other drawbacks as well. The first drawback is an unpleasant odor caused by the bacteria. The second drawback the smoke generated from the oil-laden coolant coming in contact with the operating cutting tool. One of the easiest ways to remove hydrocarbons from water or coolant is by using a belt oil skimmer. It is a low maintenance, easy to use tool for removing oil from water or coolant.

Belt oil skimmers work because of the differences in specific gravity between oil and water. Water has a specific gravity of one. Most oils have a specific gravity of less than one. Because of these differences, oil floats to the top of the water where it can be removed. A belt oil skimmer uses oil oleophilic material, (usually made of stainless steel or plastic), in the form of a belt to break the surface tension of the water to attract
and collect the floating oil. The belt passes through a set of wiper blades via a motorized head pulley where the oil is wiped off both sides of the belt. The oil then flows through the skimmer troughs and into a proper disposal container. Because the belt materials used do not attract water, very little coolant or water is picked up.

Some of the advantages of using a belt oil skimmer over other methods to remove oil are the lower initial cost compared to coalescers and other filtration systems, low maintenance, no filters to change, and no mess involved as with absorbent booms or pads. With an oil skimmer, virtually the only required maintenance is replacing a belt and wiper blade set as needed. Next, Abanaki skimmers require very little operating space, usually with no modification to the tank. Finally, our oil skimmers have pick-up rates of up to 200 gph with minimal water or coolant content. Other forms of oil removal cannot perform as well.

There are many instances where companies have turned their disposal costs into income. By using an Abanaki oil skimmer to remove oil from the coolant, one company was able to sell its used oil to be recycled instead of being charged to have the oil-contaminated coolant disposed of. Another money saving benefit was an extended coolant life resulting in lower coolant and maintenance costs. Because of this, the Abanaki oil skimmer paid for itself in a short period of time.

How to Select the Right Coolant Oil Skimmer for the Machine Shop

Posted by Tom Hobson on Oct 31, 2018 10:15:00 AM

The use of an oil skimmer in the machine shop setting holds many benefits. Removing the oil from a machine coolant tank will initiate some esthetic benefits such as cutting down on the amount of smoke generated from the cutting tool coming into contact with oil laden coolant.

When a machine is shut down for the weekend, oil has a chance to come to the surface of the coolant tank. Bacteria that are living in the coolant tank use up the dissolved oxygen in the coolant mix, a process that is sped up by having a layer of oil on the surface. This allows odor causing anaerobic bacteria to thrive, giving off that familiar “rotten egg” smell.

Contrary to popular belief the common types of bacteria found in metalworking fluids do not cause dermatitis. However, if the skin is broken, bacteria that normally inhabit the skin may enter and cause infection. The presence of phosphates and carbonates that increase alkalinity in the coolant, however, can cause dermatitis. These impurities are found in the water being used in the coolant mix.

Separating the oil from the coolant will also help reduce disposal costs. The cost of disposing of oil laden coolant is more expensive than disposing of oil. In fact, in some instances, companies may be able to re-use the oil elsewhere or sell it for recycling. Having oil free coolant can also extend its usefulness and effectiveness, reducing the expense on maintenance and coolant replacement. As the research on the different types of oil skimmers begins, a person will find that there are a variety of skimmers available to them. The most common types are the belt, disk, and tube skimmers. Each type of coolant skimmer has its advantages and disadvantages.

There are also many factors that need to be considered when choosing the correct type of oil skimmer to fit the appropriate application. Factors such as water level fluctuation, water temperature, pH level, the use of rust inhibitors, the amount of oil to be skimmed, quality, and cost, must all be considered when selecting an oil skimmer.

The use of rust inhibitors, high temperatures, and variable pH levels can affect the skimmers ability to pick up oil. Most skimmer manufacturers use a variety of materials for the skimming medium such as plastic, stainless steel, or poly blends to match the solution in which they will be used.

There are a multitude of oil skimmers on the market today. One of the most important things to be considered is the quality of the unit to be purchased. Points of interest should include construction materials, motor design, and the type of warranty that is offered. Is the skimmer housing made of metal or plastic? Is the motor fan-cooled? Does the motor use needle bearings or bronze bearings? How long does the warranty last and what does it cover? Most oil skimmers will perform as advertised, but remember the old adage that “you get what you pay for”.
