What is a significant advantage of using ozone as an oxidant?

• A. Reduces bacterial growth
• B. Has no taste
• C. Has little pH effect
• D. Is inexpensive

Answer: (C)

Using ozone as an oxidant offers the significant advantage of having little impact on the pH of the water being treated. This characteristic is particularly beneficial in water treatment processes, as it allows for the effective removal of contaminants without altering the acidic or basic nature of the water. Maintaining a stable pH is crucial for various treatment processes and helps prevent the formation of harmful byproducts.

With ozone's minimal effect on pH, operators can manage treatment processes more effectively and avoid complications that can arise from drastic pH changes, such as the solubility and precipitation of certain minerals or the efficacy of coagulants used in the treatment system. This makes ozone a versatile and valuable oxidant in water treatment applications.
