What is the process used to eliminate pathogenic organisms from water?

• A. Filtration
• B. Chlorination
• C. Disinfection
• D. Coagulation

Answer: (C)

The process used to eliminate pathogenic organisms from water is disinfection. Disinfection specifically refers to the treatment methods employed to inactivate or destroy harmful microorganisms, including bacteria, viruses, and other pathogens, thereby making water safe for consumption. While filtration is a crucial process for removing suspended solids and some pathogens, it does not guarantee the complete inactivation of microorganisms. Chlorination is often a method used in the disinfection process; however, it is a specific technique within the broader category of disinfection. Coagulation serves to aggregate particles, making it easier for them to be removed in subsequent processes, but it does not directly target pathogens. Thus, disinfection encompasses a range of techniques, including chlorination and other methods such as UV treatment, specifically focused on ensuring that harmful pathogens are eliminated from water supplies.
