Which statement describes a feature of the baffle grease trap?

• A. Grease floats to top of entrance chamber
• B. It is made of wood
• C. It requires electricity
• D. Grease sinks to bottom

Answer: (A)

Grease traps separate fats from wastewater based on density differences. In a baffle grease trap, the incoming wastewater enters an entrance chamber where the lighter fats and oils rise to form a grease layer at the top. The trap’s baffles slow the flow and keep that floating grease from exiting with the effluent, so it can be removed later during servicing. These traps aren’t made of wood, don’t rely on electricity, and the fats don’t sink to the bottom because fats are less dense than water. So, grease floating to the top of the entrance chamber describes how this system naturally separates grease.
