What is a significant advantage of using polymeric coagulants in water treatment?

The use of polymeric coagulants in water treatment primarily enhances the removal of suspended particles, which is crucial for effective water purification. These coagulants work by destabilizing the colloidal particles in the water, causing them to clump together and form larger aggregates, known as flocs. This process facilitates easier removal of these particles during subsequent filtration stages.

In addition to improving particle removal efficiency, polymeric coagulants can also positively impact the lifetime of filters. By reducing the concentration of suspended solids and organic matter that can clog filters, they allow for longer operational periods before backwashing or replacement is necessary. This leads to improved system performance and lower operational costs over time.

While there may be benefits related to reducing chemical usage or impacting taste, the most significant and direct advantages of polymeric coagulants lie in their ability to enhance the overall efficiency of particle removal and extend the filter's lifespan, making option B the most accurate choice.
