What is the common term for the processes of mixing, flocculation, sedimentation, and filtration?

• A. Advanced treatment
• B. Conventional treatment
• C. Direct filtration
• D. Blended treatment

Answer: (B)

The processes of mixing, flocculation, sedimentation, and filtration represent the traditional steps used in water treatment to remove impurities and clarify water. This approach is often referred to as conventional treatment. In conventional treatment, water initially undergoes mixing, where chemicals such as coagulants are added to promote the aggregation of particles. Following this, flocculation occurs, where the aggregated particles (or floc) form larger clumps for easier removal. Sedimentation then allows these larger particles to settle to the bottom of a tank, separating them from the clearer water above. Finally, filtration removes any remaining particles, ensuring that the treated water meets safety and quality standards for consumption. The other options present different concepts or methods within water treatment. Advanced treatment typically refers to more sophisticated processes aimed at removing specific contaminants that may not be addressed through standard procedures. Direct filtration skips the sedimentation stage, relying solely on chemical coagulation and filtration, while blended treatment refers to combining various water sources, which is not specifically about these processes. Thus, 'conventional treatment' aptly describes the comprehensive methodology defined in the question.
