Understanding Oil/Water Separators

Oil/water separators are key in managing oily wastewater. They aim to remove oil, grease, and contaminants before disposal. These systems work by using the density difference between liquids to separate oil from water.

Keeping these systems well-maintained is vital. This is true, even more so in places with high flow rates and varied oil types.

What Are Oil/Water Separators?

Oil/water separators are designed to treat wastewater by separating hydrocarbons from water. They use coalescing technology to remove oil droplets more effectively. Regular maintenance, like cleaning and replacing filters, is important.

This helps keep the system running smoothly. It also prevents failures that can happen when the system is under a lot of stress.

Importance in Environmental Compliance

Using oil/water separators correctly is important for following environmental rules. Not following these rules can lead to big fines and harm to a company’s reputation. It’s important to follow best practices to reduce environmental impact.

Proper disposal of oil is also key. This must follow local, state, and federal laws. Working with licensed waste disposal services is necessary for responsible practices. The success of these separators helps keep discharge clean and protects water ecosystems.

The Role of Coalescing Technology

Coalescing technology is key to making oil water separators work better. It helps small oil droplets join together, making them easier to remove. Modern coalescing media, like nanofiber technology, can catch particles as small as 0.1 microns. This is a big plus for industries that need very clean products.

How Coalescing Works

Coalescing is a simple yet effective process. When oil water mixtures go into the separator, the coalescing media catches the tiny oil droplets. These droplets then grow into larger ones that can easily rise to the top.

This process is made even better with smart sensors. They help adjust the filter in real-time. This keeps equipment safe and makes the system more efficient, saving money in the long run.

Enhanced Coalescing vs. Traditional Methods

Enhanced coalescing beats old methods in separating oil and water. Mechanical coalescers are strong and work well with oil and gas. Electrostatic coalescers are great for offshore platforms, helping to keep water and hydrocarbons separate.

These new technologies help keep contaminants out, protecting the environment and meeting regulations. Companies see big benefits, like less maintenance and better quality products. This makes investing in a high-efficiency oil water separator very worthwhile.

Measurement of Separation Efficiency

Measuring how well oil/water separators work is key. It shows if they meet rules, like in North America where oil limits are 10 Parts per Million (10 PPM). Good wastewater treatment helps follow rules and works well in many industries.

Defining Separation Efficiency

Separation efficiency shows how well a system removes oil from water. For example, Freytech separators use special technology to get oil levels down to 5 PPM. They can even get oil levels as low as 0.1 PPM, showing how important it is to improve wastewater treatment.

Standards: North American Hydrocarbon Limits

In North America, oil water separators must keep hydrocarbon levels low to protect the environment. These systems can handle water flow rates from 25 to over 640 gallons per minute (GPM). The EcoLine B series system, for instance, is made for moderate flow rates. It helps meet environmental rules while supporting operations.

Lowering separation levels helps use systems that manage wastewater better. This leads to more sustainable practices and a smaller environmental impact for many industries.

Key Factors Influencing Efficiency

The performance of oil/water separators depends on several key factors. The type of oil being treated and the system’s temperature are very important. Knowing these can help improve separation efficiency and get better treatment results.

Oil Characteristics and Composition

Different oils, like diesel or motor oil, have unique properties. These properties affect how well they separate from water. For example, if the viscosity difference between oil and water is too big, it makes separation harder.

The density and what the oil is made of also matter. They can change how well oil and water separate. This can affect efficiency by up to 30%. Oil droplets that are bigger separate better than smaller ones. So, the size of the droplets is very important in making good separators.

Temperature and Its Impact

Temperature is very important for oil water separator performance. When it’s warmer, fluids move more easily, helping oil and water separate better. Keeping the temperature steady can improve efficiency by 15%.

Big changes in temperature can make separation harder. This is because it changes how the oil and water behave. Keeping the temperature right, along with the right pressure, makes separators work much better.

Freytech Inc.’s Coalescing Media

Freytech Inc. has developed advanced coalescing media to boost oil water separator performance. This innovation improves separation efficiency and makes the media reusable. This leads to lower operational costs. Regular maintenance is key to getting the most out of this media, making the separation process cleaner and more effective.

Benefits of Reusable Media

The reusable nature of Freytech’s coalescing media is a big plus. It can be easily cleaned, which extends its life and cuts down on replacement costs. This helps industries meet environmental standards while keeping oil water separators running well, even in tough conditions.

Maintenance and Longevity

Keeping the oil water separator in good shape is vital for the coalescing media’s longevity. Regular cleaning stops clogs and boosts separation efficiency. By sticking to a maintenance routine, facilities can hit oil levels as low as 0.1 PPM. This meets and beats the 5 PPM oil removal rule set by regulations.

Maintenance is key to better efficiency and following environmental rules.

Optional Features for Efficiency

Adding optional features to oil water separators makes them work better. Freytech’s patented oil skimmer is a key feature. It automatically takes out the oil, making it easy to recycle.

Patented Oil Skimmer Benefits

The oil skimmers help by making the drainage process automatic. They remove oil droplets over 20 microns. This means the water can be very clean, with oil levels below 5 ppm.

Using dual adjustable rotatable pipe skimmers helps get more oil. It also cuts down on downtime.

Collection and Disposal of Separated Oil

It’s important to collect and dispose of oil properly. Good systems handle sludge well, from 27 to 85 gallons. Automatic sludge dump systems make things easier, even in tough environments.

Stainless steel and fiber-reinforced plastic make the systems last long. This saves money over time.

Types of Hydrocarbons Handled

Oil/water separators are key in managing wastewater with different hydrocarbons. Knowing these hydrocarbons is vital for better oil water separator performance. Each oil type needs a specific method for effective separation.

Common Hydrocarbons in Wastewater

In industrial settings, wastewater often contains lubricating oils, diesel, and jet fuel. These compounds challenge separation due to their unique properties. Choosing the right oil/water separator is critical for meeting standards and efficient operation.

Separation of Emulsified Oils

Emulsified oils are hard to separate because they mix well with water. Advanced technologies, like Freytech’s coalescing separators, can significantly improve separation. They can lower emulsified oil levels to 0.1 PPM. Knowing how different hydrocarbons behave helps operators pick the best separator, boosting compliance and protecting the environment.

Economic Advantages of Efficient Separators

Efficient oil/water separators are key for better financial health in industries with wastewater. They help lower costs for managing waste. These separators also boost productivity and how resources are used.

Using efficient separators cuts down on waste disposal costs. They separate oil from water, reducing landfill or treatment plant waste. This saves money on waste disposal fees.

Companies using these technologies save money over time. Their operational efficiency grows, leading to more savings.

Recycling Opportunities

Separators also open up recycling chances. They skim off reusable oil, turning waste into a valuable resource. This supports sustainability and lowers costs for buying new materials.

Adding efficient separators to industries promotes a circular economy. It improves both economic and environmental outcomes.

Regulatory Compliance and Benefits

Keeping up with regulatory rules is key for industries dealing with oily wastewater. The Environmental Protection Agency (EPA) sets rules that air compressor wastewater can’t have more than 40 parts per million (ppm) of oil. Yet, the average air compressor condensate often has around 300 ppm of oil.

Because of these strict standards, companies must use effective oil-water separators. This is to make sure they follow the rules.

Meeting 10 PPM Limit

Businesses face big fines if they don’t meet the 10 ppm discharge limit. These fines can be up to $25,000 a day. Oil-water separators are key in removing oil from wastewater before it’s released.

Companies using these systems see better reliability and fewer compliance issues. They also reduce their legal risks and improve their reputation.

Achieving Cleaner Discharge at 5 PPM

Some advanced technology lets separators achieve a 5 ppm clean discharge. This is thanks to the latest coalescing technology. It makes sure oil-water separators work well and follow the rules.

Oil Water Separation Process Description for Ecoline B Series

Following, we provide technical information and calculations regarding oil water separation with the EcoLine B 3 (50 GPM / 3 L/S flow rate)  oil water separator.

Stokes Law and other considerations as applied to Freytech oil water separators.

The oil/water mixture flows into the tank where there is sufficient dwell time for some of the solids / mud (if any are present) to sink to the bottom of this section of the tank. The oil water mixture now contains fewer solids as it continues downstream to the section of the tank where the coalescing media panel is installed. Some of the larger oil droplets present in the waste stream will start to rise to the surface and form an oil layer or a sheen floating on the surface of the water.
The wastewater still contains small oil droplets which have not had enough retention time to rise to the water surface and this waste stream continues its flow downstream and enters the coalescing media.

What actually separates the oil from the water is our oleophilic media made of washable and durable reticular polyurethane-polyether material. Oil is attracted to this media. As soon as each oil droplet in the waste stream comes into contact with the coalescing media, it is separated and immediately collides with other oil droplets which are also being simultaneously separated.

As these oil droplets continue to collide with each other, they coalesce together forming larger oil droplets and then detach from the media and rise to the water surface because of their specific weight (oil being lighter than water). 

The reticular polyurethane-polyether material which separates the oil from the water has a surprisingly large surface area given its composition and consistency.

The formula for the minimum effective surface of the coalescing media is A = 1.4 x NS m² Surface (in m²) = 1. 4 x Nominal size.
A conventional 50 GPM / 3 l/s treatment flow rate below ground separator has: 3 x 1.4 = 4.2 m2 (45 ft2 ) of minimum required coalescing surface area. The Freytech Inc. EcoLine B-ADD 3 model has  9 m2 (97 ft2) of effective coalescing surface area.

ECOSORP

FOR EMULSIFIED AND DISSOLVED OIL: (ECOSORP BELOW 1 PPM)

The EcoSorp oil water separator is for use to obtain below 1 part per million (PPM) separation efficiencies. It is for use with free or PHYSICALLY EMULSIFIED AND DISSOLVED OIL by adsorption from water. This represents exceptionally clean separation. The EcoSorp requires filter / coalescing media cartridge replacement since it works through adsorption and the media becomes saturated over time (typically once a year). Recommended for use downstream of a Freytech Inc. above or below ground 5 PPM oil water separator to prolong its useful life. The media can absorb up to 22 lbs (10 kg) of oil. Units available with flow rates up to 100 gallons per minute (GPM) / 380 liters per minute (L/M). No electrical power requirements.

Typical Fields of Application

  • For emulsified and dissolved oil. 

HIGH FLOW RATE OIL WATER SEPARATOR

Each XL Separator Panel can effectively treat oily water flow rates ranging from 320 GPM (20 l/s) to 640 GPM (40 l/s). Achieves 5 Part per Million (PPM) separation of free non-emulsified oil. By far, the most affordable method for large industrial oil-water separation since panels can be installed side by side like windowpanes in a submerged cross-wall in locally procured concrete or steel tanks. This unique solution represents a huge advantage over shipping conventional bulky separators since there is no limit to the flow rate that can be treated and the panels are washable and reusable. Maintenance is conducted from above ground making it safer, cleaner, quicker and of course, more affordable. Each panel requires 1 yard / 1 meter of submerged wall space. Optional polishing system available to also separate trace emulsified oil down to 0.1 PPM.

With the optional ADD Skimmer, the oil being separated by the XL Panels is mechanically and automatically collected 24/7 and drained by gravity to a separate receptacle. The skimmed oil will contain only 0.3% of water thus providing the operator with an outstanding 99.7 % concentration of pure used oil. This represents a significant advantage over other skimmers in that the operator no longer has to pay for the separated oil and the excess water to be removed from the separator by septic truck and shipped/ treated in a wastewater treatment plant. The operator can even sell or donate the pure separated oil since it is now possible to skim it free of water from the separator on site.
