Which approach involves multiple treatment processes to remove various water contaminants?

• A. Filtration
• B. Single-barrier approach
• C. Multiple-barrier approach
• D. Cost-effective strategy

Answer: (C)

The multiple-barrier approach is designed to effectively remove a wide range of water contaminants by employing various treatment processes in tandem. This method acknowledges that different contaminants require different strategies for removal, thus enhancing the overall effectiveness of the water treatment system. By employing multiple treatment processes, such as coagulation, sedimentation, filtration, and disinfection, the approach addresses various types of impurities, including sediments, biological contaminants, and chemical pollutants. The single-barrier approach is less effective when it comes to removing diverse contaminants, as it relies on just one method. While cost-effective strategies may consider financial aspects of treatment, they do not specifically refer to the comprehensive nature of tackling various contaminants as the multiple-barrier approach does. Therefore, the multiple-barrier method is favored in modern water treatment practices for its robustness in ensuring safe and clean water.
