Polyacrylamide (PAM) is a water-soluble polymer that has been widely used for various industrial applications due to its excellent flocculation and coagulation properties. In recent years, PAM has gained increasing attention in the field of raw water treatment due to its ability to remove impurities and improve water quality.

PAM can be used in raw water treatment processes such as sedimentation, flotation, and filtration. It acts as a coagulant aid by enhancing the efficiency of traditional coagulants such as aluminum sulfate or ferric chloride. PAM can also be used as a primary coagulant in certain raw water sources.

One of the main advantages of PAM in raw water treatment is its ability to remove suspended solids, colloids, and other impurities from the water. This results in clearer and cleaner water that is suitable for further processing or direct consumption. PAM can also improve the settling rate of solids in sedimentation basins or clarifiers, leading to a more efficient separation of solids and liquids.

Moreover, PAM can reduce the amount of coagulants required for raw water treatment, which leads to cost savings and reduces the environmental impact associated with chemical usage. PAM is also non-toxic and biodegradable, making it an environmentally friendly option for water treatment.

In summary, PAM is a versatile and effective polymer that can improve the efficiency and effectiveness of raw water treatment processes. Its ability to remove impurities, enhance coagulation processes, and reduce chemical usage make it an ideal solution for a wide range of raw water treatment applications.
