What is the term for a conical tank used for rapid softening reactions?

• A. Pallet reactor
• B. Filter press
• C. Pellet reactor
• D. Settling tank

Answer: (C)

The term that refers to a conical tank used for rapid softening reactions is known as a pellet reactor. This type of reactor is specifically designed to facilitate the quick mixing of chemicals and water, allowing for efficient softening processes, such as the removal of hardness-causing minerals from water.

In a pellet reactor, the conical shape enhances turbulence and mixing, promoting optimal conditions for the chemical reactions that lead to softening. The design enables the rapid formation of precipitates, which are then easily removed from the water.

Understanding the function of a pellet reactor is essential for water treatment processes, as it significantly influences the effectiveness and efficiency of softening treatments in municipal and industrial applications.
