The function of baffles in an interceptor is to

• A. Trap Grease
• B. Accelerate Flow
• C. Filter Solids
• D. Vent Gases

Answer: (A)

Baffles in a grease interceptor slow and direct the incoming wastewater, creating calmer pockets where separation can occur. Because grease floats to the top while solids settle, the baffles help grease collect behind the barrier, forming a trapped layer that stays in the tank rather than moving on with the flow. This arrangement increases retention time and reduces the amount of grease entering the sewer line. Accelerating flow would disrupt separation, while filtering solids or venting gases are not the primary roles of these baffles.
