          How Do Grease Traps Work?

          Grease traps operate by slowing the flow of wastewater. This allows fats, oils, and grease (FOG) to separate from the water. The denser water sinks, while the lighter FOG rises to the top.

          Inside the trap, a baffle keeps the separated layers in place. As the water passes the baffle, it exits the trap, leaving the collected grease behind. This simple yet effective method prevents FOG from entering sewage systems.

          The process is generally as follows:

          • Wastewater enters the grease trap.
          • FOG separates and rises to the surface.
          • Clean water flows out to the sewer.

          Periodically, the trap must be cleaned to maintain efficiency. Most systems require regular maintenance to function correctly. Understanding this operation helps recognise when maintenance is due. Proper operation minimises the risk of blockages and costly plumbing issues.

          Types of Commercial Grease Trap and Separator

          Commercial grease traps come in various forms, each suited to different needs. The choice depends on your kitchen's size and the volume of waste produced. Selecting the right type is crucial for effective FOG management.

          There are two primary categories: passive and automatic grease traps. Passive traps are simpler and rely on the natural separation of FOG from water. They are often more cost-effective for smaller operations.

          Automatic Grease Removal Units (AGRUs) offer greater convenience. These systems actively separate and remove grease, requiring less manual maintenance. They are ideal for larger kitchens with high output.

          Grease interceptors are another type, typically used in high-volume kitchens, and can handle significant wastewater and grease volumes. Their greater capacity makes them suitable for bustling commercial environments.

          Here's a list highlighting the main types:

          • Passive Grease Traps
          • Automatic Grease Removal Units (AGRUs)
          • Grease Interceptors

          Lastly, each type comes in various sizes and materials. Stainless steel models are durable and perform well over time. Regardless of choice, proper installation and maintenance remain key to their effectiveness.
