What is the primary purpose of flocculents in water treatment?

Flocculents play a crucial role in water treatment by assisting in the aggregation of smaller particles into larger masses, known as flocs. This process is vital because it increases the efficiency of subsequent filtration and sedimentation processes. When flocculents are added to water, they facilitate the clumping of suspended particles, which can include dirt, bacteria, and other impurities. By forming larger particle masses, flocs can be more easily removed from the water, significantly improving the quality of the treated water.

The other options do not accurately describe the primary function of flocculents. While flocculents are involved in improving the clarity and quality of water, they do not directly remove harmful chemicals from water, increase temperature, or enhance water color. Their primary focus is on particle aggregation, making option A the most suitable answer.
