Why do I need a grease trap?
Fats, oils and greases (FOGs) come from the food residue that is on used plates and cookware in commercial kitchens and are the main cause of blocked pipes. The main grease generators are pre-rinse and pot washing sinks. If these are not managed efficiently they can clog the pipes regardless of the size.
How do I keep my grease trap maintenance costs down?
Once food scraps are allowed into a grease trap they cannot get out unless they are removed when being emptied. They build up and cause blockages. If you use a good <2mm sink filter, most food scraps are captured before the waste water enters the grease trap and can be disposed of into a waste receptacle.
How often does my grease trap need to be serviced?
Generally speaking, a passive or grease removal unit should need a professional empty and clean every six months. However this is affected by what you are allowing to enter the grease trap and how much fat, oil and grease is being removed. For example, a kitchen producing high fat content fat food will need more frequent emptying than say, a salad bar. Also the amount of food scraps allowed to enter the grease trap will also affect how often it will need to be emptied.
What other factors affect grease trap operation?
Dishwashers, woks, rotisserie ovens, combi ovens, duck cookers and coffee makers may have wash processes that need to be taken into consideration. Plus coffee grains, flour, pasta can interfere with operation. We can design systems that will meet individual requirements.
What is the difference between types of grease trap?
See ‘Which grease trap’ for an explanation of how each type of grease trap works.Which grease trap?
How do I size a grease trap?
Some councils have a minimum size requirement of 500L so you need to check if this is the case in your area. The ‘rule of thumb’ guide for a passive trap is 5L per restaurant seat. So a 100 seat restaurant would need a 500L passive trap. A 150 seat restaurant would require a 750L tank. However internal grease traps are sized differently and depend on the flow from sinks into the trap. Contact us for help sizing these tanks.Contact us
What is a grease converter?
A grease converter is suitable for internal use and removes fat, oil and grease (FOG) from waste water by automatically adding enzymes to bioremediate the waste. For more information on how grease converters work see page ‘Which grease trap’.Which grease trap?
What is a grease removal unit or automatic grease trap?
Automatic grease traps can be installed internally and do not require enzymes to be added. For more information on how grease removal units work see page ‘Which grease trap’.Which grease trap?
When do I need risers for passive traps?
Risers are needed when the passive trap is installed at a depth where the access points on the top (for servicing) are below ground level. Risers are attached to the top of the tank and have removable covers that are suitable for either pedestrian or vehicular traffic. See Covers and Risers for more information.Covers and Risers
