What can be added to the sewage system if the grease exceeds permissible levels?

1. A filter

2. A chemical agent

3. A grease trap

4. A vent pipe

The correct answer is: A grease trap

Adding a grease trap to the sewage system is a highly effective solution for managing grease that exceeds permissible levels. Grease traps are specifically designed to intercept fats, oils, and greases (FOG) before they enter the sewage system. By using a grease trap, these substances are separated from the wastewater and retained in the trap, preventing them from causing blockages in pipes and ensuring that the sewage system functions correctly. Grease traps utilize a principle of gravity separation, where the lighter materials (grease and oil) float to the top, while heavier solids settle at the bottom. Regular maintenance and cleaning of the grease trap are necessary to keep it effective. Implementing a grease trap not only protects the wastewater system but also adheres to health and environmental regulations, which often mandate the use of such devices in commercial kitchens and food service establishments. While a filter might temporarily address some issues related to grease, it does not provide the same level of separation as a grease trap and is not a long-term solution for managing excessive grease levels. Chemical agents could potentially disrupt the microbial balance in the system and may not effectively manage the buildup of grease. A vent pipe serves the purpose of allowing gases to escape and can help maintain system pressure but does not directly address the
