What are grease separators?

A Rewatec grease separator, also known as a grease interceptor or grease trap, is a tank that receives wastewater containing fats, oils, and greases (FOG). The tank separates and traps FOG while allowing partially clarified wastewater to flow downstream for additional treatment.

Without a grease interceptor, FOG solidifies and accumulates inside sewer pipes. This can lead to blockages, backups, and pipe bursts that damage property and spill untreated wastewater into the surrounding environment.

Rewatec grease separators provide a simple solution. Designed for projects with medium to high flows, our autonomous systems offer total protection by effectively separating FOG from your wastewater.

How do grease separators work? 

Grease separators work on the basis that animal fats and vegetable oils do not mix with water.

Firstly, wastewater runs into a main drainage pipe that flows into the two-chamber grease interceptor.

In the first chamber, solids settle on the bottom of the tank and form sludge. This sludge is removed by a septic pumper as often as needed.

In the second chamber, gravity separates fats, oils, and greases from wastewater. These substances naturally float to the surface and form scum. A system of baffles traps scum until it can be removed and transported for safe disposal.

A low-level pipe in the second chamber collects partially clarified wastewater and releases it downstream for further treatment.

 

Operation of a Calona grease separator

 

The size of the grease separator required depends on the flow rate of fluid through the kitchen, either though sinks, dishwashers or equipment.  

 

Grease separator maintenance

Protect your property and the environment by having your Rewatec grease separator regularly serviced by a qualified professional.

The frequency of service depends on the capacity of your tank, the amount of effluent you generate, and the environmental regulations in your area. It is best to speak with a local expert to determine the service schedule that is right for you.
