Whether automatic or manual, grease traps work by trapping the FOGS that rise to the top from wastewater before it enters the drains. When wastewater enters a grease trap, it slows the water flow down significantly, separating it into solids on the bottom layer, wastewater in the middle, and FOGS on the top.
How does oil and grease separator work?
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.
What is a grease trap separator?
The Polyethylene Triple Garage Basins are designed to provide separation of FOGs (Fats, Oils, and Grease) in wastewater flowing from kitchens, restaurants, garages, car washes, parking garages, etc.
What is the difference between a grease trap and a oil water separator?
The solids compartment of a grease trap ensures that solid waste is removed from the drain — preventing blockages. Oil separators are used in industrial environments where there is the potential for oil and other hydrocarbons to be carried into the wastewater stream.
What is the purpose of grease trap?
To put it simply, a grease trap is a receptacle into which wastewater containing FOG flows through before entering a drainage system. The receptacle is designed to intercept or “trap” the FOG while allowing clear water to escape.
Are grease traps necessary?
With a commercial kitchen—whether in a restaurant, school, cafeteria, bar, or other food service establishments—the danger from fats, oils, and grease is much higher. This is why it’s necessary to have a grease trap installed and routinely serviced.
Where are oil separators used?
An oil water separator is a piece of equipment used to treat wastewater, making it safe to discharge into an approved discharge point, such as a sewer. It removes oils, grease and hydrocarbons, leaving only the non-hazardous water. The wastewater can then disposed of safely in drainage.
What happens when a grease trap is full?
If your grease trap becomes excessively full, grease will begin spilling out of the primary compartment into the secondary one. This will soon lead to clogs in the lines leading into and out of the grease trap. A full trap will also restrict the flow of water through the system.
How often should a grease trap be cleaned?
Most grease traps should be cleaned out every 1-3 months, depending on usage. To know exactly how often your business needs to attend to the grease traps, consider the “1/4th rule.” In simple terms, the grease trap should be cleaned out when it reaches a quarter of its capacity.
What is the difference between grease trap and grease interceptors?
Grease traps handle flow rates of 10–50 gallons per minute, while grease interceptors accommodate flow rates of more than 50 gallons per minute. Pressure. Grease traps work best in a low-pressure water environment, whereas grease interceptors are more appropriate for high-pressure environments.
How long does a grease trap last?
On average, steel grease traps last 5-8 years. They can be quite heavy, if buried indoors (in a concrete or tiled floor, for example) can be quite difficult to replace.
How does a residential grease trap work?
A grease trap works by cooling warm or hot greasy water. Vegetable oils and animal fats are 10 to 15% less dense than water and are insoluble in water. By allowing the fats, oils, and grease to cool, the different layers of the mixture are able to separate into individual layers for easy separation.
What is a sand interceptor?
What is a Sand/Oil Interceptor? Sand/oil interceptors are large capacity, underground vaults installed between sewer drains and the Central Contra Costa Sanitary District’s main sewer line. These vaults are designed with baffles and pipes to trap sediments and retain floating oils.
How does a triple interceptor work?
A Triple Interceptor is also known as a Food and Oil Interceptor or Grease Trap. It is a tank installed between a sink and a public sewer to prevent pollution from trade waste such as grease, fat, oil, silt, sand, sludge and other substances entering into the sewer system.
What is a grease waste line?
According to Universal Plumbing Code, “a grease trap/grease interceptor is a plumbing device that is installed in a sanitary drainage system to ‘trap’ or ‘intercept’ non-petroleum FOG from a wastewater discharge.” Wastewater flows from the sink of drain into a tank.
Why does grease trap smell?
Filthy Grease Trap
When this organic waste is broken down by the microorganisms, toxic waste such as hydrogen sulphide and sulphuric gases is emitted. The sulphuric gases are responsible for producing the foul smell inside the grease trap.
