Final answer:
Indirect waste interceptors should have a filter screen to prevent clogs by removing large and small particles, protecting wastewater treatment equipment and processes, like sand filtration and grit chambers.
Step-by-step explanation:
Every indirect waste interceptor receiving discharge containing particles that would clog the receptor drain should Have a filter screen. This is because items such as plastic bottles, cans, sticks, rocks, and even dead animals, if not removed, can cause significant damage to treatment plant equipment. A bar screen usually takes on the role of catching such large items as wastewater enters a treatment facility. Similarly, smaller particles are removed by various forms of filtration systems, including those using sand filtration or grit chambers, which are designed to remove particulates like sand or dirt by allowing them to settle out of the water, sometimes with the aid of aeration to prevent smaller particles from settling. Filtration processes are crucial for protecting the infrastructure of waste treatment facilities and ensuring the proper treatment of wastewater before it is released back into the environment or further reused.
