The purpose of an interceptor is to remove which of the following?

An interceptor is designed specifically to remove potentially fouling materials from wastewater before it enters the main sewer system. These materials can include grease, oil, and other substances that might cause blockages or disruptions in the sewer infrastructure. By capturing these substances, interceptors help to protect the integrity of the sewer system and ensure proper flow, thus preventing clogs that can lead to backups and sewer overflows.

The design and function of interceptors are critical in maintaining sanitary conditions and reducing the risk of environmental contamination. For example, grease interceptors are commonly used in commercial kitchens to prevent fats and oils from damaging the sewer lines. The removal of these potentially fouling materials is essential for maintaining the overall efficiency and effectiveness of the plumbing system.

The other options do not accurately describe the primary function of interceptors. While hazardous waste removal may be a consideration in broader environmental management, interceptors are primarily focused on substances that could degrade the performance of sewage systems rather than hazardous waste in a general sense. Moreover, interceptors do not aim to remove all solids or clean water, as some solids may be managed in the wastewater treatment process or through various filtration and treatment mechanisms that come after the interceptor stage.
