Which component is NOT part of conventional water treatment?

• A. Filtration
• B. Sedimentation
• C. Coagulation
• D. Direct filtration

Answer: (D)

Direct filtration is not typically considered a part of conventional water treatment processes. Conventional water treatment generally includes multiple distinct stages designed to effectively remove contaminants before water is released for distribution. These stages include coagulation, sedimentation, and filtration. Coagulation involves adding chemicals to water that cause small particles to clump together into larger masses, which can be more easily removed. Sedimentation follows coagulation, allowing these clumps, known as flocs, to settle at the bottom of a tank. Filtration then serves to remove remaining particles and microorganisms from the water through various media, ensuring a high quality of treated water. Direct filtration, in contrast, is a simplified process where water is passed through a filtering medium without the preceding steps of coagulation and sedimentation. This method is typically used for water sources that are already relatively clean or when rapid treatment is necessary. Thus, it does not align with the traditional, multi-step approach of conventional water treatment.
