Types of Grease Containment Systems
Grease containment systems are essential in various industries to prevent the release of grease and oil into the environment. These systems not only help in complying with environmental regulations but also protect equipment and infrastructure from damage caused by grease buildup. In this article, we will explore different types of grease containment systems and their applications.
1. Grease Traps
Grease traps, also known as grease interceptors, are one of the most common types of grease containment systems used in commercial kitchens and food processing facilities. These systems are designed to capture and separate grease, oil, and solids from wastewater before it enters the sewer system.
Grease traps work on the principle of gravity separation. The wastewater flows into the trap, and as it slows down, the grease and oil rise to the top due to their lower density. The solids settle at the bottom, leaving relatively clean water in the middle. The separated grease and oil are then periodically removed and disposed of properly.
Grease traps come in various sizes and configurations to accommodate different flow rates and grease loadings. They are typically made of durable materials such as stainless steel or polyethylene to withstand the corrosive nature of grease and oil.
2. Grease Interceptors
Grease interceptors are similar to grease traps but are designed for larger applications such as restaurants, hotels, and industrial facilities. These systems are capable of handling higher flow rates and larger volumes of grease and oil.
Grease interceptors work on the same principle as grease traps, but they have a larger capacity and additional features to enhance their performance. They often have multiple compartments to allow for better separation and retention of grease and oil. Some grease interceptors also incorporate automatic skimming devices to remove floating grease continuously.
Grease interceptors are typically installed underground, and their size and design depend on factors such as the flow rate, grease load, and local regulations. Regular maintenance and cleaning are crucial to ensure the proper functioning of grease interceptors.
3. Grease Recovery Units
Grease recovery units, also known as grease recovery devices or GRDs, are specialized systems used in commercial kitchens and food processing facilities to recover and recycle grease and oil. These systems are designed to separate grease and oil from wastewater and convert them into a usable byproduct.
Grease recovery units use a combination of physical and chemical processes to separate grease and oil from wastewater. The recovered grease and oil can be further processed to produce biodiesel or used in other applications such as animal feed or lubricants.
Grease recovery units are highly efficient and can recover a significant amount of grease and oil that would otherwise be wasted. They not only help in reducing environmental pollution but also provide a valuable resource that can be reused or sold.
4. Grease Containment Berms
Grease containment berms are specialized systems used in industrial facilities and transportation hubs to contain and control grease and oil spills. These systems are designed to prevent the spread of grease and oil and minimize the impact on the environment.
Grease containment berms are typically made of durable materials such as polyurethane or PVC and have a flexible design that allows them to be easily deployed and repositioned as needed. They are often used in areas where the risk of grease and oil spills is high, such as loading docks, fueling stations, and maintenance facilities.
Grease containment berms can be customized to fit specific requirements and can be equipped with additional features such as drain plugs, connectors, and ramps for easy access. Regular inspection and maintenance are essential to ensure the integrity of grease containment berms.
5. Grease Duct Systems
Grease duct systems are specialized systems used in commercial kitchens and food processing facilities to safely vent and exhaust grease-laden air. These systems are designed to prevent the buildup of grease and oil in ventilation systems, which can pose a significant fire hazard.
Grease duct systems consist of a series of ducts, hoods, and filters that capture and remove grease and oil particles from the air. The captured grease and oil are then collected in grease traps or interceptors for proper disposal.
Grease duct systems are subject to strict regulations and standards to ensure their safety and effectiveness. Regular cleaning and maintenance are crucial to prevent the accumulation of grease and oil, which can lead to fire incidents.
Grease containment systems play a vital role in preventing the release of grease and oil into the environment and protecting equipment and infrastructure from damage. Grease traps and interceptors are commonly used in commercial kitchens and food processing facilities, while grease recovery units are used to recover and recycle grease and oil. Grease containment berms are used to contain and control grease and oil spills, and grease duct systems are used to safely vent and exhaust grease-laden air. Understanding the different types of grease containment systems and their applications can help industries choose the most suitable solution for their specific needs.

Frequently asked questions about Types of Grease Containment Systems.
What are grease containment systems and why are they necessary?
Grease containment systems are engineered solutions designed to capture and contain grease and oils discharged from commercial kitchen exhaust systems. They play an integral role in commercial kitchens, including restaurants, cafeterias, and any other establishments that involve large-scale food preparation.
These systems are essential because they prevent grease and other particulates from entering the exhaust system and collecting on the roof or other structures. Accumulated grease can pose a fire risk, damage the roof, create unpleasant odors, and attract pests. Furthermore, grease discharge can lead to regulatory fines if not properly managed.
What are the different types of grease containment systems?
There are primarily three types of grease containment systems: rooftop grease containment systems, downspout grease containment systems, and in-duct grease containment systems.
Rooftop Grease Containment Systems: These are often the first line of defense in a commercial kitchen. They are designed to capture grease that exits from the exhaust fan and prevent it from accumulating on the rooftop. These systems generally consist of a catch basin and absorbent pads or hydrophobic filters to soak up the grease.
Downspout Grease Containment Systems: These systems are typically installed at the end of a downspout that drains the grease from the rooftop system. They can have a filter system that separates grease from water, allowing water to flow freely while trapping the grease for disposal.
In-Duct Grease Containment Systems: Installed directly within the exhaust ductwork, these systems catch grease before it has a chance to exit the duct. They often use metal baffles to filter the grease-laden air.
Each of these systems has unique advantages and is chosen based on the specific needs of the establishment.
How do I decide which grease containment system is best for my needs?
The ideal grease containment system depends on a variety of factors, including the volume and type of cooking, the layout and design of your kitchen and exhaust system, local codes and regulations, and budget considerations.
Rooftop systems are commonly used when there’s heavy grease output and easy roof access. Downspout systems may be chosen when the structure is designed such that the grease is carried down from the roof via downspouts. In-Duct systems can be great if space is limited or there are specific fire safety or cleanliness concerns that need to be addressed.
An experienced commercial kitchen professional or a local fire inspector can help you assess your needs and select the best system.
What kind of maintenance do grease containment systems require?
Grease containment systems require regular maintenance to ensure they function properly. This maintenance typically involves inspecting and replacing the grease absorbent pads or filters, cleaning the catch basin, and ensuring the system is not overfilled.
The frequency of maintenance will depend on your cooking volume and the specific system installed. However, as a general guideline, the system should be inspected and cleaned monthly. High-volume kitchens may require more frequent maintenance.
Remember, a poorly maintained grease containment system can lead to fire hazards, regulatory fines, and expensive damage repairs. Regular maintenance is an investment in the long-term safety and efficiency of your kitchen.
Do grease containment systems help in maintaining compliance with local codes and regulations?
Yes, properly installed and maintained grease containment systems play a crucial role in ensuring your establishment remains compliant with local fire codes and health regulations.
Many jurisdictions have specific requirements for the management of grease discharge from commercial kitchens, and failure to comply can result in substantial fines or even the temporary closure of your establishment.
By installing a grease containment system, you not only help protect your property from the risk of grease fires and damage but also demonstrate your commitment to operating a safe and compliant business. However, it’s essential to consult with a local fire inspector or a commercial kitchen professional to ensure your system meets all necessary local requirements.
