Which water treatment process is characterized by a micro coagulant?

The choice of ozone treatment as the process characterized by a micro coagulant aligns with the understanding of various water treatment methods. Ozone, a powerful oxidant, is often used in water treatment for disinfection and to improve the removal of impurities, including organic matter.

During the ozonation process, micro coagulants may be utilized to enhance the coagulation and flocculation of suspended particles, leading to more efficient disinfection and clarifying of water. This micro coagulant assists by causing the smaller particles to agglomerate into larger clusters, making them easier to remove.

In contrast, activated carbon filtration primarily focuses on adsorption for the removal of organic compounds and does not typically involve micro coagulants. Ultrafiltration is a membrane technology that physically separates particles based on size and does not rely on coagulation. Similarly, reverse osmosis uses a permeable membrane to separate contaminants from water and does not incorporate micro coagulants in its operation. Therefore, ozone treatment stands out as the most appropriate answer regarding the use of micro coagulants in a water treatment process.
