Gravity-based separation
The separation chamber uses hydraulic retention and density difference to separate free-floating food-service FOG without a powered grease-separation mechanism.
GRAVITY SEPARATION + POWERED LIFTING
Gravity Grease Interceptor with Wastewater Lifting Station
Use gravity-based FOG separation upstream and a powered lifting section downstream for commercial kitchen drainage below the sewer connection level.
Selection noteThe grease-separation process is gravity-based. Electrical power is required for pumps, level controls and the control panel.
PRODUCT DETAILS
A closer look at the product
A clear separation of passive and powered functions
Gravity-based grease separation uses hydraulic retention and density difference for free-floating food-service FOG. The downstream wastewater lifting pumps and controls are powered and selected to match the project flow and discharge elevation.
CORE ADVANTAGES
Designed for selection, access and service
Integrated powered lifting
The downstream lifting section pumps pretreated wastewater to the required discharge elevation.
Simple process arrangement
A straightforward internal flow path can support routine inspection and scheduled cleaning.
304 stainless-steel option
304 stainless steel may be available for defined models. The final material grade and thickness must be confirmed.
Multiple service chambers
Internal screening, separation and collection zones are configured according to the selected model.
Project-specific pump controls
Duty/standby pumps, level sensors, alarms and remote signals can be specified where available.
HOW IT WORKS
A clear process path
- 1
Kitchen wastewater enters the screening or solids-control section.
- 2
Flow passes through gravity separation chambers where free-floating FOG rises and heavier solids settle.
- 3
Pretreated wastewater enters the downstream lifting chamber.
- 4
Level controls start and stop the powered pump system.
- 5
Wastewater is lifted to the downstream sewer connection.

FAQ
Before you request a model
Is the complete system unpowered?+
No. Grease separation is gravity-based, but the wastewater lifting pumps, level controls and control panel require electrical power.
What type of grease can be separated?+
The system is intended for free-floating fats, oils and grease from commercial kitchen wastewater. Emulsified oil, detergent-heavy wastewater or industrial mineral oil requires separate evaluation.
How often must the interceptor be cleaned?+
Cleaning frequency depends on flow, FOG loading, food solids and operating hours. Establish a maintenance schedule after commissioning and adjust it according to actual accumulation.
Can the pumps be configured as duty and standby?+
Where supported by the selected model, duty/standby pumps and alarm outputs can be specified. Confirm the required redundancy during selection.
What details are needed for a quotation?+
Provide the design flow, kitchen fixture schedule, inlet and discharge elevations, lifting head, pipe distances, room size, power supply and required controls.
