Question

Which of the following processes/mechanism (most appropriately) are thought to occur in the filtration process used in the water treatment?

• A. Ionic layer compression, mechanical straining, absorption and charge neutralization, interceptive bridging
• B. Mechanical straining, weakening and absorption, biological metabolism and electrolytic changes
• C. Mechanical straining, ionic layer compression, absorption, and charge neutralization, interceptive bridging
• D. Sedimentation and absorption, charge polarization, interceptive bridging and electrolytic changes

Hint:

Focus on understanding the different mechanisms that contribute to the filtration process, as these are essential for effective water treatment.

Answer 1

The Correct Option is C

Filtration in water treatment involves several mechanisms like mechanical straining, ionic layer compression, absorption, and charge neutralization, as well as interceptive bridging. These processes help to remove particles from the water by trapping them in the filter media and neutralizing their charges.
