Anionic polymers are commonly used in water treatment to improve floc stability. These polymers are negatively charged, which allows them to interact effectively with positively charged particles in water, such as suspended solids and impurities. When added to the water, anionic polymers help to bind these particles together, forming larger aggregates known as flocs. This process improves the efficiency of sedimentation and filtration, leading to clearer and cleaner water.

The improved floc stability ensures that the formed flocs remain intact and do not break apart easily during the treatment process, thus enhancing overall treatment effectiveness. This quality is particularly beneficial in various water treatment processes, including coagulation and clarification.

In contrast, reducing pH levels, enhancing chlorine residual detection, and oxidizing contaminants are not primary functions of anionic polymers. Each of these tasks involves different chemicals and processes specific to their respective roles in water treatment.
