Components of an Oil Water Separator

An oil water separator has key parts that work together. They help separate oil from water well. Knowing these parts is important for the system to work right and meet environmental rules.

Coalescing Media

Coalescing media is very important in oil water separators. It helps oil droplets stick together into bigger ones. These bigger droplets then float to the top of the water, making separation easier.

The quality of the coalescing media affects how fast and well oil is separated. Good design and quality are key for better results.

Oil Skimmer Options

There are different ways to remove oil from water. Freytech Inc. has special oil skimmers that automatically drain the oil. This keeps the oil clean, with up to 99.7% purity.

Using these advanced oil skimmers makes oil water separators more efficient. They are essential for many uses.

How Oil Water Separators Function

The oil water separator works mainly by using gravity. This method helps separate oil and water effectively. The flow is designed to make separation better, leading to cleaner results.

Oil and water have different densities. This makes it easy to separate them in the process.

The Separation Process

When the mixture goes into the separator, it starts to get purified. The goal is to cut down oil content to 100 parts per million or less. This is before moving on to the next steps.

The separator’s design helps bigger oil droplets float up. At the same time, the denser water stays at the bottom. This natural process makes it easy to remove oil and get cleaner water. It’s key for following environmental rules.

Coalescing Technology Explained

Coalescing technology makes the oil water separator even better. It uses special media to join small oil droplets into bigger ones. This makes the separation process more efficient.

With this technology, the system can remove hydrocarbons to levels of 30 parts per million. Oil water separators with coalescing plates can last over 20 years. They also help avoid expensive fines from regulators.

Keeping an eye on the system and using heating coils can make separation even better. This ensures the system meets discharge limits.

Water Filtration - EcoStorm - What is an Oil Water Separator

Typical Maintenance Practices

Regular maintenance is key to keeping oil water separators working well. Cleaning the coalescing media is a must. It removes oil and debris, keeping the separator efficient. Cleaning should happen every six months, but this can change based on how much it’s used and local rules.

Operators use tools like wrenches, cleaning agents, filters, and seals for maintenance. These tools help them do the job right.

Cleaning Coalescing Media

Cleaning the coalescing media means checking for problems and making sure levels are right. It also means filters are clean to avoid clogs. A pressure washer helps get rid of waste, keeping the system running smoothly.

It’s important to dispose of oil properly. This keeps the environment safe and follows the law.

Monitoring System Performance

Checking how well the oil water separator works is important. Operators should test it often and watch oil and water levels. Keeping maintenance records helps track the equipment’s health.

These records help the separator last longer and work better. This saves money and keeps the system in line with local rules.

Differences Between Oil Water Separators and Other Systems

It’s important to know the differences between oil water separators and other systems. Oil water separators use gravity and coalescing technology to separate oil from water. This is better than traditional filters, which often can’t handle emulsified oils or finer particles.

Comparison with Traditional Filtration

Traditional filters use mechanical means to remove particles from fluids. They might not work well for small oil droplets. On the other hand, oil water separators are better at removing these small droplets. They can separate up to 98% of oil droplets smaller than 10 microns.

Advantages Over Gravity Separators

Gravity separators are cheap but not always effective for high-flow conditions or emulsified oils. Oil water separators use advanced technologies like hydrocyclones and coalescing media. For example, hydrocyclones can make water almost oil-free, which is great for meeting strict environmental rules.

Oil water separators are more reliable and efficient than gravity systems. They are key in industries like oil refineries and manufacturing. For more on oil extraction, check out this page.

Common Challenges Faced

Oil water separators are key in many industries, helping meet environmental rules. Yet, they face several common problems. These issues can make them less effective. It’s important to tackle these problems to get the most out of oil water separators.

Dealing with Emulsified Oil

Emulsified oil is a big challenge for oil water separators. It happens when tiny oil droplets stay mixed with water. This makes it hard for traditional systems to separate them.

Companies need to use new technologies to better separate oil from water. This helps keep the treated water clean, as required by laws.

Managing Flow Rate Variability

Changes in water flow can affect oil water separators. Too much water can overwhelm them, making them less effective. It’s vital to have good plans and strategies for these changes.

By choosing the right equipment and setting it up well, industries can keep their separators working well. This is true even when the water flow changes a lot.

Innovations in Oil Water Separation Technology

The field of oil water separator technology has seen big changes. New systems use advanced coalescing technologies. This makes them much better at separating oil from water.

These systems can now reach very low levels of oil in water. This is important for meeting strict environmental rules.

Enhanced Coalescing Advances

New oil water separators use better coalescing media, like HD Q-PAC. This design has a lot of surface area for oil to stick to. It can remove almost all oil droplets over 20 microns.

These systems work well because they don’t let oil get mixed back in. This is thanks to their design and flow rates.

Future Trends

The future looks bright for oil water separators. We’ll see more automated systems that work better and need less human help. These changes will make things easier and safer.

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

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.
