Landfill leachate is one of the most challenging types of wastewater to treat due to its complex composition, high organic load, and high concentration of ammonia nitrogen. Without proper treatment, it can cause serious environmental pollution. Hengfeng’s high cationic polyacrylamide (PAM) has proven to be an effective flocculant in addressing the specific challenges of landfill leachate treatment.

Characteristics of Landfill Leachate

High COD (Chemical Oxygen Demand)

High BOD (Biochemical Oxygen Demand)

High content of refractory organic matter and ammonia

Presence of heavy metals and suspended solids

Why Use Hengfeng High Cationic PAM?

Hengfeng high cationic polyacrylamide is specially designed for wastewater with high organic content. Its excellent charge neutralization ability allows it to effectively combine with negatively charged colloidal particles, resulting in rapid flocculation and sedimentation.

Application Process

Pre-treatment: Adjust the pH of leachate to 6.5-7.5 for optimal flocculation.

Coagulation: Use polyaluminum chloride (PAC) or ferric chloride as coagulants.

Flocculation: Add Hengfeng high cationic PAM after coagulant dosing. The PAM molecules bridge and aggregate the destabilized particles into larger flocs.

Separation: Flocs settle quickly and are removed through sedimentation or flotation processes.

Advantages of Hengfeng High Cationic PAM

High Efficiency: Excellent removal of suspended solids and turbidity.

Cost Reduction: Reduces the consumption of coagulants and improves solid-liquid separation efficiency.

Strong Adaptability: Performs well even under fluctuating wastewater conditions.

Environmental Compliance: Helps meet discharge standards for COD, ammonia nitrogen, and heavy metals.

Hengfeng’s high cationic polyacrylamide is an ideal solution for landfill leachate treatment. With superior flocculation performance and economic benefits, it helps landfill operators and environmental engineers manage challenging wastewater streams efficiently and sustainably.
