What process is used to control the growth of algae and protozoa in water?

• A. Chlorination
• B. Filtration
• C. Boiling
• D. Flocculation

Answer: (B)

The process used to control the growth of algae and protozoa in water is chlorination. Chlorination involves adding chlorine or chlorine compounds to water, which serves as a disinfectant to kill or inactivate microorganisms, including algae and protozoa. Chlorination is a common and effective method used in water treatment facilities to ensure that water is safe for consumption and free from harmful pathogens. Filtration, while it can remove particulate matter and some microorganisms mechanically from water, does not specifically target the growth of algae or protozoa. It is more focused on the physical removal of larger particles. Boiling water can kill many microorganisms, but it is not a practical or efficient method for controlling algae and protozoa on a large scale, especially in municipal water supplies. Flocculation is a process used to aggregate suspended particles so they can be removed from water but does not specifically target microbial growth; rather, it is part of the physical treatment process that precedes filtration. Overall, chlorination is the most effective and widely practiced method for controlling algae and protozoa in water treatment processes.
