In a slate-and-coke-tray aerator, sloping sides that protect against splash losses are called what?

• A. Drip edges
• B. Splash guards
• C. Splash aprons
• D. Aeration baffles

Answer: (C)

In a slate-and-coke-tray aerator, the sloping sides designed to protect against splash losses are referred to as splash aprons. These features help to minimize water losses due to splashing, which can occur during the aeration process. By effectively directing water back into the system and reducing the potential for evaporation, splash aprons enhance the efficiency of the aeration process.

Understanding the function of the splash apron is crucial in water treatment, as it contributes to maintaining the intended operational parameters and ensuring that the water is treated effectively. This design consideration is one of several that engineers take into account when designing aeration systems to optimize performance and reduce water loss.
