NINGBO INNO PHARMCHEM CO.,LTD. is committed to providing essential chemicals for effective environmental management, and our Anionic Polyacrylamide (APAM) is a vital component in municipal sewage treatment. This versatile polymer plays a crucial role in enhancing the efficiency of sewage purification processes, ensuring cleaner water discharge and more manageable sludge.

The Importance of Municipal Sewage Treatment

Municipal sewage systems collect wastewater from homes and businesses, containing a complex mixture of organic matter, suspended solids, pathogens, and other pollutants. Effective treatment is paramount to protect public health and the environment. Key stages in sewage treatment include primary clarification (removing settleable solids), secondary treatment (biological removal of dissolved organic matter), and tertiary treatment (polishing, nutrient removal, and disinfection). Flocculants like APAM are critical throughout these stages, particularly in enhancing solid-liquid separation.

APAM's Role in Sewage Treatment Processes

Anionic Polyacrylamide is highly valued in municipal sewage treatment for several reasons:

  • Primary Clarification: In the initial stages, APAM helps to aggregate fine suspended particles that may not settle readily on their own. By forming larger flocs, it improves the efficiency of sedimentation, removing more solids and reducing the organic load entering secondary treatment.
  • Secondary and Tertiary Treatment: APAM can be used to further clarify treated effluent, removing residual suspended matter and improving the overall quality of the discharged water.
  • Sludge Dewatering: This is perhaps one of the most significant applications of APAM in municipal sewage treatment. The sludge produced from the treatment process is often characterized by high water content and fine particles. APAM acts as a conditioner, binding these particles and forming larger, more compact flocs. This greatly improves the efficiency of dewatering equipment, such as belt filters and centrifuges, leading to a drier sludge cake. A drier sludge cake means reduced disposal volume, lower transportation costs, and often, a more stable material for further processing or landfilling.

Benefits of Using APAM

The effectiveness of APAM in municipal sewage treatment is underscored by several benefits:

  • High Efficiency: APAM demonstrates strong flocculation and dewatering capabilities, often requiring lower dosage rates compared to conventional chemicals.
  • Cost-Effectiveness: Its high performance at low concentrations translates into significant cost savings in chemical consumption and sludge disposal.
  • Environmental Compliance: By improving water clarity and reducing sludge volume, APAM helps treatment plants meet stringent environmental discharge regulations.
  • Versatility: APAM can be used in various stages of sewage treatment, adapting to different operational needs.
