Apr 2, 2024 · How does a grease trap function? Step 1: Coarse solids in used water are removed when the water passes through the screen chamber. Step 2: Smaller solids in used water are further removed at the strainer bucket. Step 3: Less dense fat, grease, and oil in used water are separated as the water enters and circulates around the outer ring chamber.
Grease traps work on the basis that animal fats and vegetable oils (grease) are 10 to 15 percent less dense than water and that grease won’t mix with water. Thus, fats and oils float on top of water. When wastewater enters a grease trap, the flow rate is reduced enough so the wastewater is given enough time to cool and separate into 3 layers.
A grease trap (also known as grease interceptor, grease recovery device, grease capsule and grease converter) is a plumbing device (a type of trap) designed to intercept most greases and solids before they enter a wastewater disposal system. Common wastewater contains small amounts of oils which enter into septic tanks and treatment facilities ...
What is a Grease Trap? Grease traps or grease inceptors have been in use since Victorian times, with the first patent for a modern-day grease trap issued to Nathaniel Whiting in the late 1800s. Grease traps vary in size, with smaller variations designed to connect individual sinks and larger ones installed to service larger facilities.
Apr 19, 2024 · A grease trap works by using gravity to separate FOG from wastewater. The FOG floats to the surface, the grease trap fills from the top down as grease enters it, and grease-free water exits into the sewer lines. This process removes FOG before entering your plumbing system or a wastewater treatment facility.
The use of grease traps to prevent FOG from getting into the sewer system dates as far back as the Roman Empire. The modern grease trap design was invented in 1884 and its technology has remained nearly unchanged ever since. Whether the unit is a grease trap or grease interceptor, the technology works the same.
Apr 19, 2024 · Scoop the bucket in to the trap, and bring out the solidified waste. Place the waste in a water-tight container, such as a heavy-duty plastic trash bag. 6. Scrape down the lid and the sides of the trap with your bucket. Remove any large pieces of fat or oils that are attached to the trap.
In the most basic terms, a grease trap works by slowing down the flow of warm/hot greasy water and allowing it to cool. As the water cools, the grease and oil in the water separate out and float to the top of the trap. The cooler water - minus the grease - continues to flow down the pipe to the sewer. There are two primary methods that grease ...
Dec 18, 2023 · Grease traps play a crucial role in preventing untreated sewage from being released into the environment. The function of a grease trap is to effectively separate and capture fats, oils, and greases (FOGs) from the wastewater. Grease, being lighter than water, naturally rises to the top of the trap. The trapped grease is then contained within ...
It is a plastic wall inside a grease interceptor tank to slow down and often control the flow of water.) The captured grease fills the trap from the top down. Grease-free water exits out of the bottom of the trap into the sewer lines. Peer into a grease trap and you’ll see a mat of grease. When this mat of grease gets deep enough, the trap ...
