In drinking water treatment, cationic polymers are often used in combination with coagulants, such as aluminum and iron salts, to enhance the removal of turbidity and microorganisms. These polymers improve the efficiency of the coagulation-flocculation process, leading to clearer water with reduced pathogen levels. Moreover, the use of cationic polymers can also reduce the amount of chemical coagulants required, which is beneficial for both environmental and economic reasons.

Corrosion is another major issue in chilled water systems that can lead to equipment damage and unscheduled downtime. The presence of dissolved oxygen, carbon dioxide, and chlorides can exacerbate corrosion processes. To mitigate this risk, corrosion inhibitors, such as nitrites, phosphates, or azoles, are added to the chilled water. These inhibitors form a protective film on the metal surfaces, effectively shielding them from corrosive agents. Implementing a tailored chemical treatment program not only prevents corrosion but can also extend the lifespan of the system components.
