A gravity separator box is a type of equipment used in both municipal and industrial wastewater treatment systems to remove suspended solids and oils from wastewater through gravitational separation. This device capitalizes on the differences in density between various components in the wastewater mixture. As wastewater enters the gravity separator box, the heavier solids settle at the bottom while lighter materials, such as oils and grease, rise to the surface. The clarified water, free from these contaminants, can then flow out for further treatment or be discharged.

Gravity separator boxes provide an effective and economical solution for the removal of solids and oils from wastewater. Their simplicity, efficiency, and environmental benefits make them a preferred choice in both municipal and industrial settings.
