Which of the following additives is effective in preventing FOG build-up?

Chemical degreasers are effective in preventing FOG (Fats, Oils, and Grease) build-up because they contain ingredients specifically formulated to break down and emulsify fats and oils. These additives work by altering the physical and chemical properties of the grease, which helps to disperse it in the wastewater system, preventing it from accumulating on pipes, pumps, and other components of the collection system.

This is crucial in maintaining the efficiency and functionality of the sewage system, as FOG build-up can lead to clogs, backups, and costly maintenance issues. By using chemical degreasers, facility operators can proactively manage FOG levels and reduce the risk of blockages and operational disruptions.

The other options, while useful in different contexts, do not specifically target the breakdown and prevention of FOG. Anti-corrosive agents are designed to protect surfaces from corrosion but do not address grease accumulation. Multipurpose cleaners may serve various cleaning functions but are not focused on emulsifying grease in a wastewater context. Oxidizing agents can help oxidize organic matter but are typically not the most effective for specific FOG prevention.
