• Improved Flocculation: Polyacrylamide helps to aggregate the fine particles within the sludge into larger flocs, a process necessary for effective dewatering. This results in a faster separation of solids from water.
• Increased Filtration Efficiency: When applied before the mechanical dewatering steps, such as belt press filtration or centrifugation, polyacrylamide facilitates the formation of a more robust floc structure. This robust structure withstands the mechanical stresses better, allowing for more effective water removal and leading to drier sludge cakes.
• Optimization of Chemical Dosage: The right type and amount of polyacrylamide can be optimized based on the specific characteristics of the sludge, such as its organic content and the nature of solids. This optimization ensures maximum dewatering efficiency while minimizing chemical usage and operational costs.
• Enhanced Water Quality: By improving the separation of solids and liquids, polyacrylamide helps to produce a filtrate or centrate with lower suspended solids content. This contributes to a higher quality of the water that is either discharged or recycled back into the treatment process.

What is a sludge dewatering polymer?

Sludge dewatering polymer is a chemical compound used in the process of sludge dewatering, which is the removal of water from sewage sludge.

The polymer is added to the sludge to help separate the solid and liquid components, making it easier to remove the water from the sludge.

The most commonly used sludge dewatering polymers are cationic polymers, which have a positive charge and are attracted to negatively charged sludge particles.

When the polymer is added to the sludge, it forms a bond with the particles, causing them to clump together and form larger particles.

This makes it easier to remove the water from the sludge, as the larger particles settle more quickly and are more easily filtered.

Other types of polymers used in sludge dewatering include anionic and nonionic polymers. Anionic polymers have a negative charge and are used to help break up the sludge particles, while nonionic polymers have no charge and are used to improve the sludge's dewatering properties.

Overall, the use of sludge dewatering polymers is an important step in the treatment of wastewater, as it helps to reduce the volume of sludge and make it easier to dispose of or reuse.

Description of Sludge dewatering Polymer

• Blufloc Polyacrylamide (PAM)/ Polyelectrolyte is a water-soluble polymer with Anionic, Cationic, and Nonionic types.
• The series of molecular weight is various, Anionic is from 5-22 million, Cationic is from 5-12 million and Nonionic is from 5-12 million, with a charge density ranging from 0-60%.
• It is frequently used to increase the viscosity of water (developing a thicker solution) or to encourage the flocculation of particles present in water.
• Due to the polar groups on the molecular chain consisting of a specific quantity, it can through the adsorption of solid particles suspended in water, bridge between particles or through the charge and make the particle development of large flocs condensation. So, it can accelerate the settlement of particles in suspension, undoubtedly to accelerate the service to clarify, promote filtering, and other results.
• Mainly utilized for various commercial wastewater flocculation information, sedimentation, and sedimentation treatment, such as iron and steel plant wastewater, electroplating wastewater, wastewater metallurgy, coal washing wastewater treatment, and sludge dewatering. Can likewise be used to clarify and consume water purification treatment, and sugar & juice mills.
• Soluble in water, safe, non-toxic, hydrolytic stable, is not sensitive to the change of pH value, and is anti-chlorine. Safe, non-flammable, and non-explosive, it can be stored at space temperature, and it can not be put in the sun. It is slightly acidic, when skin contact, wash it immediately with plenty of water.
