Is Oil Skimmer Maintenance Necessary? | Abanaki

Posted by Tom Hobson on Feb 21, 2020 9:13:44 AM

If you’re not reclaiming your used oil than you are awarded no points, may not collect $200, or pass Go. If you are, you get all of the points. However, if you are doing this but NOT taking care of the equipment that is helping you reclaim that used oil, then you are just as much a part of the losing team.

Maintenance Needed?

Just like any piece of equipment; cars, computers, those 5-in-1 breakfast sandwich maker machines, all of them need tinkering and routine maintenance in order to keep the gears turning and the eggs fluffy. With that being said, oil skimmer maintenance is crucial in not only ensuring proper waste oil recovery, but overall success of your entire operation.

Over the years we have seen some troubling scenes. The things people do to oil skimmers…it is horrific. Years upon years of oil and incalculable layers of gunk encrusted all over the machine. Discharge valves clogged to the point where the skimmed content barely drips out. THE ORIGINAL BELT. For shame. All of you.

Quick Overview of How Oil Skimmers Work

If you’re not familiar with how oil skimmers work, here’s a quick overview: Although designs vary, all oil skimmers rely on specific gravity, surface tension and a moving medium to remove floating oil from a fluid's surface.

Floating oil and grease cling to skimming media more readily than water, and water has little affinity for the media. This allows skimming media in the shape of a belt, disk, drum, etc. to pass through a fluid surface to pick up floating oil and grease with very little water. This oily material is subsequently removed from the media with wiper blades or pinch rollers.

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.

What is Tramp Oil? | Abanaki

Posted by Tom Hobson on Jan 24, 2020 9:30:00 AM

Tramp oil is a term that describes any unwanted hydrocarbon-based substance that contaminates machine coolant. This issue occurs mostly metalworking and manufacturing industries. Tramp oils can lead to numerous problems that affect work environment safety, production efficiency, and the cost control abilities.

What causes Tramp Oil?

How do these hydrocarbon-based substances find their way into a coolant sump?

There are a few different avenues.

Machining centers employ various linear motion and rotary motion components such as bearings, slides, ball screws, and spindles that require lubrication to function efficiently. Over time, these lubricants can find their way to the machining center platform where they mix with cutting fluid or coolant.

Another source of contamination is from the materials being processed in the machining center. Most stock metals have a corrosion prevention coating which is typically oil based. If the oil based coating is not removed prior to machining, it will end up mixing with the coolant.

Problems Associated with Tramp Oils

Tramp oil contaminated coolant causes a variety of problems if not separated and removed.

First, the coolant’s performance ability suffers. This is because oil in coolant reduces the coolant fluid’s ability to reduce temperatures effectively. Any oil that is present in the cutting fluid will promote heat generated by the tool, which can shorten tool life considerably.

Another consequence of oil coming in contact with a hot cutting tool is smoke. At high temperatures, the oil can become hot enough to burn. This can create unsafe working conditions.

When left alone, tramp oils that settle in coolant become breeding grounds for anaerobic bacteria. The oil essentially prevents oxygen from mixing with the coolant, which can promote the growth of anaerobic bacteria. Workers who come in contact with these bacteria are susceptible to contact dermatitis. The bacteria can also generate hydrogen sulfide gas, which emits an unpleasant rotten egg odor.

Removal & Separation Solutions

There are two common methods for removing tramp oils from coolant. These are coalescers and oil skimmers.

Coalescers consolidate small oil particles into larger droplets. Filters or baffles are then gather larger droplets for removal. Coalescers are a good option for larger area applications as they have greater collection area than skimmers.

Skimmers utilize the differing specific gravities between oil and coolant/water to remove tramp oils. A motor driven belt that is typically constructed of an oleophilic, or oil attractant material, is placed into a coolant sump or reservoir. As the belt moves through the coolant, it attracts tramp oils. The oil is scraped off by a wiper and deposited into a container.

Seven Advantages of Using Oil Skimmers | Abanaki

Posted by Tom Hobson on Jan 21, 2020 11:32:53 AM

 

Waste oil recovery is critical to any application for a multitude of reasons. Many companies try, or should be trying (tsk tsk if you’re not), to recover their used oil in order to stay in compliance with government standards and regulations. No one wants to pay a massive fine or even worse, donning the orange jump suit with silver bracelets, when complying with the law and keeping our environment clean is a simple enough task.

Additionally, recovering used oil has its monetary perks. Reclaimed hydrocarbons can be sold for profit and removing it properly can help extend the life of equipment, waste water, or coolant. All while Mother Earth smiles and the people rejoice. Everybody wins.

Here are the seven advantages of using oil skimmers.

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.

Oil Skimmers: Simple Solution to Serious Issue

Oil skimmers are very simple pieces of equipment that can help you tackle a very serious wastewater issue. They are a low-cost and environmentally sound solution to waste oil recovery. They are by no means high-maintenance or difficult to use, but do require some routine work every now and then and a little tinkering here or there. Bottom line is, replacing a wiper blade system or belt on an oil skimmer beats having to pay a fine to your respective government environmental agency. If you are not sure about the laws are regarding wastewater in your area, we have a handy database of environmental links indexed by location for you to use.

How to Keep Machine Coolant from Smelling | Abanaki

Posted by Tom Hobson on Dec 16, 2019 10:15:00 AM

Anyone that works with coolant knows about the potential foul stench that looms around the corner. 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.

Coolant Mints

Abanaki offers a wide range of coolant maintenance products. One of these items is our Coolant Mints. These tablets are safe to handle and eliminates odors by neutralizing them, not covering them with perfumes or fragrances. The Coolant Mints contain zero formaldehyde and causes zero issues with disposal. 1 tablet per week can maintain 25 gallons of coolant! 

Coolant Skimmers or Tramp Oil Skimmers

The presence of a coolant skimmer or tramp oil skimmer in a machine shop holds many benefits. One of the benefits is to drop in “rotten egg” smell from bacteria reacting with oil on the top of coolant tanks.

Coolant skimmers or tramp oil skimmers remove tramp oil to extend the life of coolant, prevent hazardous conditions, and subsequently, get rid of the “rotten egg” smell. Depending on the applications, coolant skimmer will also bring your tool shop an improved working environment, extended tool life and reduced maintenance costs.


All of our coolant skimmers are rugged, reliable and low maintenance. Removal capacities range from 1 to 200 gallons per hour. Browse the types of oil skimmers and oil skimming accessories in our website www.abanaki.com or contact our experts at 440-543-7400 to find the right solution for your application.

Six Reasons to Remove Oil from Water | Abanaki

Posted by Tom Hobson on Dec 11, 2019 9:30:00 AM
A crucial step many industries must take in a manufacturing process is to remove oil from water. Whether it is to comply with government standards and avoid fines or trying to cut down on disposal costs, there are a number of advantages companies enjoy when they use oil skimmers to remove oil from water.
 
 
Reasons to Remove Oil from Water

Here are six reasons why manufacturers need to remove oil from water and how Abanaki oil skimming technologies offer a cost-effective solution.

  • Gallon of used motor oil can contaminate million gallons of fresh water.
  • The U.S. generates billion gallons of waste oil each year and million gallons are not disposed properly.
  • Sources of oily wastewater include exhausted oil emulsion from machine tools, used coolants, water used in parts washing and grease from food processing, etc
  • Dumping oily wastewater into a storm sewer could lead to years in prison and/or hefty fines.
  • Hiring a licensed disposal firm to haul away and treat oily wastewater or coolant can cost larger manufacturers thousands of dollars per month!
  • Oil skimmer technology can dramatically reduce the water content of waste oil that must be disposed of or recycled.

Oil and water don’t mix,” a statement that manufacturers in a variety of industries have come to learn the hard way. Oil skimming technologies offer an environmentally safe, highly economical approach to separating oil and water prior to disposal.

Skimming Away Coolant Contamination with Tramp Oil Skimmers | Abanaki

Posted by Tom Hobson on Nov 25, 2019 10:15:00 AM

Machine tool coolant fluid contaminated with tramp oil can cause problems. For instance, contamination reduces fluid life and deteriorates the quality of machined parts. As the problem worsens, the tramp oil accelerates bacterial growth, and the cutting fluid eventually produces a rotten-egg odor. Besides the odor, bacteria-contaminated coolant can more serious issues such as dermatitis.

The Solution: Oil Skimmers

However, there is solution. Oil skimmers remove contamination. They are inexpensive, highly dependable, and typically pay for themselves within a few months. Although designs vary, most use moving media and rely on differences in specific gravity and surface tension between oil, water, and the skimmer medium.

Different Kinds of Oil Skimmer Media

Skimmer media comes in various shapes, and the most common are belts, disks, or tubes. As the medium moves through the cutting fluid, it picks up non-emulsified oil, which subsequently enters a removal section of the skimmer. Wiper blades or pinch rollers remove oil from the medium and routes it into a container for reclamation or disposal.

More advice: Oil Skimmer Motor

Selecting the proper style oil skimmer not only controls coolant contamination but also provides a clean, safe work environment. It’s also important to make sure the skimmer motor is robust enough to handle the intended application.

Skimmer motor housings, no matter what type of skimmer, should completely enclose the wiring and be tightly secured. Loose fitting housings with weak fastening may come off unintentionally, exposing wiring and increasing the risk of electrical shock. The housing should also be well ventilated so the motor does not overheat.

Shops also need to check motor specs, making sure the system is rated for continuous service. To shave costs, some manufacturers opt for intermittent-duty motors. Using this type of motor for more than two or three hours a day generally causes overheating.

Additionally, keep in mind that skimmed oil and water inevitably get on the motor shaft. So, it is important that the motor’s seals effectively prevent unwanted fluids from migrating along the shaft and contaminating the bearings.

Coolant Oil Skimmer With Benefits | Abanaki

Posted by Tom Hobson on Nov 18, 2019 10:30:00 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.

Bacteria Build-Up with “Rotten Egg” Smell

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.

Cost-Saving with Coolant Oil Skimmer

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.

Other Factors to be Considered in Oil Skimming

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”.

11 Characteristics that define Oil Skimming Application | Abanaki

Posted by Tom Hobson on Oct 31, 2019 1:15:00 PM

There are several types of industrial oil skimmers. Choosing a unit best suited for an application will maximize oil removal while lowering maintenance and operating cost. You may define the application in terms of the following characteristics:

Operating Conditions

The performance and life of the pick-up medium, wiper blades, pulleys, etc. are affected by operating conditions. These include temperatures in and out of the liquid, the pH of the solution and the presence of solvents or other reactive chemicals.

Hazardous Materials

Applications involving flammable materials or explosive vapors require the use of explosion-proof (or air-driven) motors and controls.

Temperature/Viscosity

All oil skimmers require floating oil to be in a liquid, free flowing state. If the oil congeals or solidifies at ambient temperatures, the reservoir and/or skimmer will require heaters to maintain fluid flow.

Removal Rate

Skimmer removal rates, expressed in gph, vary with oil viscosity. Typically, manufacturers rate skimmers using SAE 30 weight motor oil at 65 degrees Fahrenheit (18 degrees Celsius). It's wise to ask for test data, especially if your application involves a much different viscosity. 

Skimmed Water Content

All oil skimmers pick up some water with the oil. Suction skimmers pick up more water than other types. High water content increases oil recycling and disposal costs. Generally, the ratio of water to oil decreases with thicker films of floating oil and slower moving pick-up media.

Residual Oil

A skimmer removes oil as long as it is present. Depending on oil influx rate and the skimmer's removal rate, residual oil in the water may be as low as a few parts per million.

Portability

In some plants mobile equipment service shops and at remediation sites, a portable oil skimmer can sometimes service multiple machines, sumps or wells.

Tank or Sump Characteristics

The location, shape and capacity of a tank or water impoundment are major factors in choosing the right skimmer. Also consider fluctuations in water level, turbulence and possible emulsions.

Size/Design

Oil and water can emulsify when subjected to turbulence and other mechanical agitation. Avoid this by having water return to the tank below the liquid surface at as low a velocity as practical.

Shape

Tanks without nooks and crannies for oil to accumulate in are best. If you have an irregular shape, put the skimmer where the largest amount of oil accumulates.

Location/Installation

Questions to ask about the physical location and characteristics of the tank and collection container: Does skimmed material need to be pumped from the skimmer to the container? Will skimmer access for periodic maintenance be a problem?

How Do Disk Oil Skimmers Work? | Abanaki

Posted by Tom Hobson on Oct 30, 2019 2:41:30 PM

Disk oil skimmer provides an inexpensive way to remove unwanted tramp oils from CNC coolants and parts washers.

Disk Oil Skimmer Operation

Disk 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. When specifying disk diameter, it is important to consider reach, the portion of the disk that actually gets immersed. Less disk area in the fluid means less oil removed. Obviously, fluctuating fluid levels can be a real problem. Also, it is important to look at how much of the disk the wipers are actually wiping. If they wipe only 2 inches from the edge, then any reach into the fluid beyond 2 inches is wasted. As a result, removal capacities for disks can be relatively low.

When properly selected and applied, disk oil skimmers are highly economical solutions for separating oil from water to allow its reuse or safe disposal.

What is Tube Oil Skimmer? | Abanaki

Posted by Tom Hobson on Sep 26, 2019 1:13:56 PM

 

Tube oil skimmer is a surface tube oil skimmer that can effectively removes floating surface oils by means of an oleophilic (oil attracting) 3/4 inch diameter continuous looped tube. The tube extends out over the surface of the tank or pit and collects the free floating oils.

Abanaki tube oil skimmer (The Oil Viper) has a specially designed method for removing the oil from the tube. It has a unique wiper combination attached to the tube itself in addition to the ceramic wiper on the skimmer. The result is a virtually oil free tube as it leaves the surface oil skimmer for quicker oil removal. Removal rates can be as high as one hundred gallons per hour.

How Does a Tube Oil Skimmer Work?

The Oil Viper tube oil skimmer can be used in wastewater applications that are shallow in depth. The Oil Viper tube oil skimmer is a great fit where a belt skimmer is too big. Due to the sleek design of the Oil Viper tube oil skimmer it can skim in just inches of water compared to a belt skimmer which could need one to two feet of water to skim from.

The Oil Viper tube oil skimmer works off the same principle of the belt skimmer, the tube breaks the surface tension of the water, the oil is then collected and skimmed off by its unique wipe clean design. Two tube materials are available, the standard tube is great in a wide variety of applications; the high temperature tube is best suited for high temperature or caustic applications.

Large Tube Oil Skimmer  

Large tube 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 fluid surface area for proper operation. Length considerations are the same as for belt skimmers; a typical tube diameter is 1 inch.

Small Tube Oil Skimmer

Mini tube skimmers are very similar to the larger tube units, but typically have either a 3/16-inch or a 5/16-inch diameter tube. The 5/16-inch diameter is preferable as it has enough stiffness to not drag on the housing and prematurely wipe off oil when drawn into the unit. Pickup rates vary from 1 quart/hour to 1.5 gph, depending on diameter and speed. These units can be used where space is limited. Units that have the motor mounted underneath reduce the amount of space required over the rim of the tank to nearly zero.
