Organic coagulant, also known as a natural coagulant, refers to a substance derived from organic sources that is used in water treatment processes. It serves as an alternative to traditional inorganic coagulants, such as aluminum or iron salts.
Organic coagulants are primarily used for their coagulation and flocculation properties in water treatment. When added to water, they help destabilize and aggregate suspended particles, colloids, organic matter, and other contaminants present in the water. This aggregation forms larger and heavier particles called flocs, which can be more easily removed through sedimentation, filtration, or other separation processes.
Moreover, organic coagulants are effective in removing a wide range of impurities, including organic compounds, color, turbidity, algae, and certain pathogens. They can be applied in various water treatment applications, including drinking water treatment, wastewater treatment, industrial water treatment, and the treatment of surface water sources like lakes and rivers.
