2As large generators of oily wastewater tighten effluent controls, the U.S. Environmental Protection Agency (EPA) is targeting smaller generators. Some of the firms receiving their attention are smaller manufacturing plants, automotive garages, mobile equipment service shops and truck farms. Many of these firms do not have access to a sanitary sewer system that will accept oily wastewater.
Because disposal in storm sewers also is prohibited, they frequently use injection wells, septic system drain-fields, dry wells and ground pits to dispose of oily wastewater; one EPA concern is that oily wastewater will find its way into an underground aquifer that is a source of drinking water.
Many oily wastes contain organic and inorganic chemicals in concentrations that exceed the primary drinking water standards established by the Safe Drinking Water Act. So, the focus of one EPA program is aimed at preventing contamination of groundwater by controlling oily wastewater recycling at the generator’s site.
Getting Rid of Oily Wastewater
If oily wastewater isn’t recycled, it must be disposed of safely. One option is to have it collected and hauled away by a licensed disposal firm. The annual volume of oily wastewater generated by many shops and plants makes hauling too costly.
Even firms connected to sanitary or industrial wastewater sewer systems have limitations on the oil content in their effluent. When oil concentration exceeds a certain level, usually 100 ppm or less, the generator can get hit with hefty surcharges by the local government providing wastewater treatment.
At some level of oil concentration, the oily water effluent is prohibited from entering the sanitary sewer line.
Wastewater Recycling
With wastewater recycling, the most common methods of oil/water separation include decanting tanks, oil skimming, coalescing, membrane separation and various chemical treatments. Any of these methods can be effective. Selection should be based on economic as well as technical considerations.
Although it is a cost-effective method of reducing contamination, oil skimming often is overlooked as a primary technique. Frequently, this results from the misperception that skimming is only suitable as a pretreatment ahead of other oil/water separation devices.
Certainly, skimming is a retreatment method used to prevent oil overloads in downstream membranes, coalescers and sand bed filters. But it can stand alone as an oil removal method in many applications, reducing oil to only a few parts per million concentrations, depending on conditions. In many locales, this is good enough to allow the water to enter a sanitary sewer system without paying connection surcharges.
More exotic methods of oil removal, such as membrane filtration and chemical treatment, are most often required when tight emulsions and other chemicals must be removed. If an emulsion is the water-in-oil type, a skimmer may do the job.
Types of Oil Skimmers
Oil skimmers usually incur a low initial cost, install easily, offer rugged construction, reliable operation and minimal upkeep. Training personnel for operation, monitoring and routine maintenance is nil.
Still, there are different types of skimmers, and each application requires some analysis to make the best selection. Also, the water collection system must be set up properly in order to get maximum performance from the skimmer.
The six major skimmer configurations for industrial plants and service shops are belt, disk, drum, mop, tube and floating suction types. For all types, the oil or other hydrocarbon liquids must be floating on top of the water. For all but the floating suction type, a moving skimmer medium is pulled through or across the surface to attract the oil.

Coolant oil skimmers typically don’t come attached to CNC machines when they are newly bought. This is because nobody wants to admit that the brand-new machine is eventually going to leak oil into the coolant. This looks good on paper, but there is a reason why so many coolant oil skimmers are bought annually.
CNC machines are bound to have at least a small amount of oil leaking into the coolant at some point. The skimmer will remove this oil from the top of the coolant for disposal. Without some type of coolant oil skimmer, the coolant life will be dramatically decreased. These small coolant oil skimmers will save you money throughout the operational life of your CNC machine.
The Crucial Role of Coolant Oil Skimmer on CNC Machine
A coolant oil skimmer plays a crucial role in enhancing the performance and longevity of CNC (Computer Numerical Control) machines. These machines rely on coolant oil to lubricate and cool the cutting tools, which is essential for maintaining high precision and preventing damage due to excessive heat. However, coolant oil tends to become contaminated with various substances such as tramp oil, metal shavings, and debris during the machining process. This contamination can adversely affect the machining process, leading to reduced efficiency and increased maintenance requirements.
The implementation of a coolant oil skimmer effectively addresses this issue by efficiently removing the contaminants from the coolant oil. By removing tramp oil, which is the accumulated oil from leaking machine parts or hydraulic systems, the skimmer prevents the formation of a sticky residue on the workpiece, reducing the need for post-machining cleaning. This results in improved surface finish and higher product quality. Moreover, by removing metal shavings and debris, the skimmer helps prevent clogging of the coolant system, ensuring smooth coolant flow and minimizing the risk of tool damage.
Additionally, a coolant oil skimmer contributes to cost savings and environmental sustainability. By efficiently separating tramp oil from the coolant, it extends the life of the coolant oil, reducing the frequency of coolant replacements and the associated costs. Moreover, the skimmer aids in the recycling and reusing of the separated tramp oil, minimizing waste generation and promoting environmental conservation. Overall, the benefits of a coolant oil skimmer on CNC machines include improved machining performance, reduced maintenance requirements, enhanced product quality, cost savings, and a more sustainable manufacturing process.
Different Types of Coolant Oil Skimmers
There are several different types of coolant oil skimmers available for CNC machines, each with its own unique design and method of operation.
- Belt Skimmers: Belt skimmers consist of a continuous belt that is immersed in the coolant. The belt attracts and collects the floating oil as it passes through the coolant, and then the oil is scraped off the belt and collected in a separate container.
- Disk Skimmers: Disk skimmers utilize a rotating disk that is partially submerged in the coolant. The disk’s surface tension attracts the oil, which is then scraped off the disk and collected for removal.
- Tube Skimmers: Tube skimmers employ a hollow tube or suction head that is inserted into the coolant. The oil is drawn up through the tube by a vacuum or suction mechanism, separating it from the coolant, and then it is transferred to a collection container.
Each type of coolant oil skimmer has its advantages and is suitable for different applications based on factors such as the type of coolant used, the volume of oil to be removed, and the specific requirements of the CNC machine.
