What is the purpose of a backwash process in water treatment?

  1. To Refresh Chemicals

  2. To Clean Filter Media

  3. To Add Clarity

  4. To Measure Efficiency

The correct answer is: To Clean Filter Media

The backwash process in water treatment is specifically designed to clean filter media. During normal operation, filters capture dirt, sediment, and other particles from the water, which can lead to clogging and decreased efficiency over time. The backwash method reverses the flow of water through the filter media, dislodging the accumulated contaminants. This cleaning action restores the filter’s effectiveness, allowing for continued efficient filtration of water. In contrast, the other options, while relevant to water treatment processes, do not accurately describe the core function of backwashing. Refreshing chemicals pertains to the addition of treatment chemicals to improve water quality, which is distinct from the mechanical cleaning of a filter. Similarly, adding clarity generally refers to processes aimed at improving the visual quality of the water, such as using coagulants or flocculants, rather than the maintenance of filter media. Measuring efficiency might relate to monitoring the overall performance of the water treatment system but does not encompass the specific cleaning role that backwashing provides for filters.
