Question: What is the primary purpose of a 'grease interceptor' or 'grease trap' in a building drainage system?
Answer options:
- To prevent soil and debris from entering the municipal sewer system. ✅ To separate fats, oils, and grease (FOG) from wastewater before it enters the sanitary sewer.
- To reduce the temperature of hot wastewater discharge.
- To neutralize acidic waste from industrial processes.
Correct answer: To separate fats, oils, and grease (FOG) from wastewater before it enters the sanitary sewer.
Explanation: Grease interceptors are specifically designed to collect and retain fats, oils, and grease (FOG) from kitchen wastewater, preventing them from solidifying in the downstream plumbing and municipal sewer lines, which can cause significant blockages. They are not primarily for soil, temperature reduction, or acid neutralization.
