What is the difference between a hydro mechanical grease interceptor and a gravity grease interceptor?
What is the difference between a hydro mechanical grease interceptor and a gravity grease interceptor?
Gravity-type units are identified by their holding volume in gallons. The other category of interceptors is known as hydro- mechanical. These units increase separation performance through the use of flow control, air intake and baffles, which markedly decreases the time necessary to separate.
What is the purpose of a grease interceptor?
A grease interceptor is located between kitchen drain lines and sanitary sewer lines. Grease interceptors capture the FOG that enters sink drains from food service activities such as food preparation, dishwashing and cleaning.
What is a grease interceptor and how does it work?
How does a grease trap work? Grease traps work on the basic principal that FOG's float on water and solid particles sink. Baffles within the trap slow the inflow of wastewater from the kitchen sinks. This allows for a settlement period where the separation of oils, water and food particles within the unit.
How do you calculate the GPM of a grease trap?
To size a Gravity Grease Interceptor with the flow determined in GPM you simply multiply the flow number by a detention time, 30 minutes (the time period normally excepted for the grease to separate by buoyancy). Again with our 20 GPM example, the size would be 20X30= 600. A 600 Gallon size interceptor would be used.
What sizes do grease traps come in?
The common sizes available today are 10,15,20,25,35,50,75,100 GPM. are 300, 500, 750, 1000, 1250, 1500, 2000, 3000 Gallons.
How big are restaurant grease traps?
Typically, for small food establishments, a 550 litre grease trap would do. On the other hand, larger premises would usually need something with a bigger capacity, such as 1500 to 3000 litre grease traps.
How many types of grease traps are there?
There are 3 main types of grease trap; passive hydromechanical (manual), automatic and gravity.
What is the difference between grease trap and grease interceptor?
Grease traps are much smaller (typically about the size of bread box to a small mini-fridge), while grease interceptors are much larger. Capacity/flow. Grease traps handle flow rates of 10–50 gallons per minute, while grease interceptors accommodate flow rates of more than 50 gallons per minute.16 mar 2020
Is a grease trap necessary?
A grease trap keeps harmful buildup away from the sewer line. ... The city doesn't want to deal with massive blockages in the sewer system because of businesses sending fats, grease, oil, and extra food waste into the sewer lines. This is why grease traps are usually legally required for foodservice businesses.16 oct 2017
What kitchen equipment requires a grease trap?

Where are grease traps required?
It follows from this that grease traps must be installed in appropriate premises which include: Hotels, restaurants, hospitals, bakeries, fast food chains etc. There are also a number of further laws and regulations which although are not exclusively about grease traps relate to it in some way.16 ene 2015
How does a small grease trap 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.
How does a grease trap work in a house?
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.
How much does it cost to install a small grease trap?
On average, a small grease trap installation costs between $250 and $1500. Grease trap replacement costs may seem expensive at first, but that's nothing in comparison to how much money you'll need to shell out if you need to replace it. Having a functioning grease-catching solution pays off in the long run.
