Which treatment method is often faster than traditional methods?

• A. Sedimentation
• B. Direct filtration
• C. Chlorination
• D. Sand filtration

Answer: (B)

Direct filtration is a treatment method that combines coagulation, flocculation, and filtration into a single step, allowing for a quicker processing time compared to traditional methods. In direct filtration, water is treated with chemical coagulants and then passed directly through a filter without the extended settling time required in sedimentation techniques. This streamlining of the process reduces the time needed to clarify water, making it a more efficient option in many treatment scenarios. In contrast, sedimentation requires a significant amount of time for solids to settle before water can be filtered, which can lengthen the overall treatment process. Chlorination, while effective for disinfection, does not assist in the rapid removal of particulates or turbidity, and sand filtration, although widely used, typically involves a longer water treatment cycle as compared to direct filtration. Hence, direct filtration stands out for its speediness in certain situations.
