Overview of Oil Water Separators

Oil water separators are key in many industries like oil and gas, manufacturing, and wastewater treatment. They help keep the environment clean and make sure operations run smoothly. Knowing what they do is important for companies that want to follow the law and work well.

Definition and Purpose

Oil water separators are made to pull oil, grease, and other harmful substances out of water. Their main job is to keep our water clean by removing bad stuff from it. This is very important because many businesses have to follow strict rules about how much oil they can release into the water.

Key Functionality

These separators work by using gravity, differences in density, and mechanical actions. It’s very important they work right, or it can cost a lot and even lead to fines. Newer technologies can get rid of pollutants as small as 0.1 PPM, which is way better than what old rules required.

Comparing Above Ground and Below Ground Separators

It’s important to know the differences between separators for the best performance and upkeep. Above ground and below ground separators have unique designs. These designs affect how well they work and how easy they are to maintain.

Structural Differences

Above ground separators can handle more volume, making them great for big oil and gas operations. Below ground separators are smaller and better for tight spaces. The design of each affects their efficiency and how often they need maintenance.

Horizontal separators, common in oil and gas, can handle lots of fluid. But, they might need more maintenance because of corrosion and buildup.

Ease of Access and Maintenance

It’s easier to get to above ground separators for checks and repairs. Keeping oil water separators in good shape is key for their performance. Below ground systems can be harder to maintain, taking more time to get to parts.

Regular checks are important for both to prevent problems and keep them running smoothly.

Environmental Impact

Separators play a key role in managing waste effectively. They must follow strict rules to protect our water. The goal is to keep hydrocarbon levels in water below 10 Parts per Million (PPM).

Thanks to new technologies, separators can now remove hydrocarbons to just 0.1 PPM. This is a huge step towards keeping our water clean. It also helps in managing waste in an eco-friendly way.

Compliance with North American Hydrocarbon Discharge Limits

Rules on hydrocarbon discharge are strict to keep facilities responsible. They must monitor their waste closely and use advanced technologies. This helps avoid breaking the rules.

Some places have even stopped wastewater violations by using bioremediation. The use of enhanced coalescing technology also lowers pollutant levels. This shows how important following these rules is.

Advantages of Enhanced Coalescing Technology

Enhanced coalescing technology also makes operations more efficient. It has led to a big drop in sludge petroleum content, over 80%. It also cuts down on maintenance costs.

This technology not only helps the environment but also saves money. It’s a win-win for both the planet and businesses.

Performance Metrics

It’s key to know how well oil separators work. Traditional methods can only get oil levels down to 5 PPM. But, newer systems can hit 0.1 PPM, a huge leap forward. This shows how important it is to pick the right system for your needs.

Separation Efficiency: 5 PPM vs. 0.1 PPM

Getting the best out of oil-water separation is critical. Systems that can get oil levels under 0.1 PPM do much better than older ones. These systems meet strict rules and make water discharge quality better.

To reach such low oil levels, separators must be well-designed, maintained, and operated. Following industry best practices is essential.

Types of Hydrocarbons Separated

Different hydrocarbons need different ways to be removed. Freytech’s Enhanced Coalescing Oil Water Separators are great at handling various fuels. This includes motor oil, diesel, gasoline, and jet fuel.

Each fuel type has its own challenges. The right separator depends on the type of hydrocarbon. Knowing this helps choose the best separator for top performance and efficiency.

Durability and Lifespan

The durability of oil separators is key to their effectiveness and cost savings. Knowing how long they last is important for businesses that use them. The use of reusable coalescing media is a big plus for their long life.

Reusable Coalescing Media

Coalescing media for oil separators can make them last longer by being cleanable and reusable. This helps save money and is good for the planet. It means these separators can work for a long time, helping both the environment and business profits.

Maintenance Requirements

Keeping coalescing media in good shape is vital for separators to work well and last long. Regular checks and cleanings are needed for both types of separators. Above ground models are easier to maintain, which means less time off work.

This ease of maintenance is a big plus when choosing a separator. It makes operations more efficient and is a key factor to consider.

Cost Considerations

When looking at oil-water separators, the cost is key. This is true for both above ground and below ground types. The price can change a lot based on the materials and design.

FRC’s above-ground CPI systems are made from top-quality stainless steel. This makes them last longer but costs more upfront than cheaper materials.

Initial Investment vs. Long-term Savings

Choosing quality materials and new tech can save a lot of money in the long run. These systems need little upkeep. For example, FRC’s chain-and-flight skimmer works well with thick oils.

This means less wear and tear, and fewer breakdowns. This helps facilities save money and work better, even when they’re busy.

Value of Recycled Oils

Getting oil back from water is another money-saving perk. When oil is removed well, it can be reused. This can make a big difference in profits.

API separators are great at handling lots of oil. This means more oil to sell, which can help pay for the cost of good systems. All these points make the cost of oil separators very important to think about.

Installation and Setup

Installing oil-water separators right is key to their success. This part talks about what you need for the site and how long it takes to set them up. It helps with planning and getting the right resources.

Site Requirements for Above and Below Ground Options

Choosing the right spot for oil separators is important. Above-ground ones need less work and fit well in places like car washes. They require space for upkeep and to collect waste.

Below-ground setups need more digging and planning. They also must meet rules like EN 1825 for grease traps in food places. Both types must follow these rules.

Timeframe for Installation

How long it takes to put in separators depends on the type. Above-ground ones go up fast because they’re easy to get to. This means they can be ready in just a few days.

But, below-ground ones take longer. They need digging and more planning. This can make the setup time go up to weeks. Knowing this helps plan better and get things done on time.

Case Studies

Looking at real-world examples shows how effective above ground separators are. Many industries have used these systems to solve oil-water separation problems. They’ve found these systems boost efficiency and meet environmental rules.

Successful Implementation of Above Ground Separators

Studies show how above ground separators improve wastewater treatment. Construction and mining have seen big benefits from these units. They remove at least 99.9% of droplets, thanks to their strong design.

The tanks are made of 11-gauge stainless steel, lasting through tough conditions. The SPT series can handle up to 100 GPM, meeting different wastewater needs.

Lessons Learned from Below Ground Systems

Below ground systems have taught us important lessons. They’ve shown us the need for easy maintenance and protection from groundwater. These lessons help us see why above ground systems are better.

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.
