At NINGBO INNO PHARMCHEM CO.,LTD., we are constantly exploring innovative approaches to enhance the effectiveness of water treatment processes. One of the most powerful strategies involves the synergistic combination of our High Molecular Weight Cationic Polyacrylamide (CPAM) with inorganic coagulants, such as polyaluminium chloride (PAC) or ferric salts. This combined approach leverages the distinct strengths of both types of chemicals to achieve superior results in water clarification and sludge dewatering.

Inorganic coagulants, like PAC and ferric chloride, work by neutralizing the charges of suspended particles through a process called coagulation. They form amorphous, gelatinous precipitates known as metal hydroxides. While effective in destabilizing fine particles, these coagulants often produce small, slow-settling flocs that can be difficult to remove completely. This is where CPAM comes into play.

When CPAM is introduced into a system that already contains destabilized particles from inorganic coagulants, it acts as a bridging agent. The long polymer chains of CPAM adsorb onto multiple destabilized particles, effectively linking them together. This bridging action creates larger, more robust flocs than either chemical could produce alone. The high molecular weight of our CPAM is particularly beneficial, as it provides a more extensive network for particle aggregation.

The synergistic effect leads to several key advantages in water treatment:

• Improved Floc Formation: The combined action results in denser, stronger flocs that settle more rapidly.
• Enhanced Settling and Filtration: Larger flocs are easier to separate from water, leading to improved clarity in sedimentation tanks and more efficient filtration.
• Increased Solids Capture: The robust flocs created by the synergy lead to a higher percentage of contaminants being removed from the water.
• Reduced Sludge Volume: The efficient dewatering achieved through this combined approach often results in less sludge being produced overall, or drier sludge that is easier to handle.
• Cost-Effectiveness: By optimizing the performance of both types of chemicals, it may be possible to reduce the overall dosage of each, leading to significant cost savings.

This synergistic approach is particularly valuable in challenging industrial wastewater treatment scenarios, where high concentrations of contaminants or varying water chemistries might hinder the performance of single-agent treatments. For instance, in sludge dewatering applications using belt filter presses or centrifuges, the combination can lead to substantially drier cakes and higher throughput rates.
