What are grease separators?

A Rewatec grease separator, 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.

It is designed for a both commercial and industrial applications and is available for a variety of business sizes.

How do grease separators work? 

Grease separators work on the basis that animal fats and vegetable oils do not mix with water. Wastewater enters the separator and the grease and oil rise to the surface. It is trapped using a system of baffles.
