Ensuring the availability of clean water and adhering to strict environmental discharge standards are paramount for both municipalities and industries. Polyacrylamide (PAM) stands out as a critical chemical agent in wastewater treatment, acting primarily as a coagulant and flocculant to remove pollutants and clarify water. NINGBO INNO PHARMCHEM CO.,LTD., a leading polyacrylamide manufacturer in China, provides a comprehensive range of PAM products designed to optimize wastewater treatment processes.

Wastewater, whether from domestic sewage systems or industrial operations, contains a complex mixture of suspended solids, colloidal particles, dissolved organic matter, and other contaminants. Effective removal of these substances is essential to protect public health and the environment. PAM's unique polymer structure allows it to address these challenges efficiently.

Mechanism of Action: PAM works in two primary ways in wastewater treatment::

  1. Charge Neutralization: Many contaminants in wastewater carry negative surface charges. Cationic PAM, with its positive charge, effectively neutralizes these charges. This destabilizes the particles, preventing them from repelling each other and allowing them to begin clumping together.
  2. Bridging: Both cationic and anionic PAM polymers are long-chain molecules. Once particles are destabilized, these long chains can adsorb onto multiple particles simultaneously, physically linking them together. This 'bridging' action forms larger, heavier flocs that settle out of the water much more rapidly and effectively than individual particles.

Applications in Wastewater Treatment:

  • Primary Coagulant/Flocculant: PAM is often used in conjunction with inorganic coagulants (like aluminum sulfate or ferric chloride) to enhance the formation and settling of primary flocs.
  • Sludge Dewatering: This is one of PAM's most significant roles. After settling solids are collected, they form a sludge that must be dewatered to reduce its volume for easier disposal or transport. Cationic PAM is particularly effective in dewatering municipal sewage sludge and industrial sludges from sectors like paper manufacturing, food processing, and chemical production. Our company is a top polyacrylamide supplier for these dewatering needs.
  • Clarification: In sedimentation tanks, PAM helps produce clearer effluent by ensuring that even the smallest particles are aggregated and removed.
