Which of the following is a chlorine alternative for water treatment?

Chlorine alternatives for water treatment are substances that can effectively disinfect water and control microbial growth without the negatives often associated with chlorine, such as the formation of harmful disinfection byproducts. Chlorine dioxide and hydrogen peroxide both serve as viable alternatives in various water treatment processes.

Chlorine dioxide is effective at killing bacteria, viruses, and protozoa, making it a strong disinfectant. It is often favored over chlorine due to its lower tendency to form trihalomethanes and other regulated disinfection byproducts, aligning better with modern safety standards for drinking water treatment.

Hydrogen peroxide also functions as a disinfectant, providing an alternative that breaks down into water and oxygen, which eliminates concerns about residuals in the water supply. Its ability to act as a strong oxidizer allows it to effectively eliminate pathogens in water treatment applications.

Together, both chlorine dioxide and hydrogen peroxide expand the options available for water treatment professionals looking to ensure safe and clean drinking water, minimizing health risks associated with traditional chlorine usage. Therefore, both these substances are considered valid alternatives, supporting the choice that encompasses both options.
