Descrizione del prodotto


Flocculant (PAM) in Heavy Metal-Contaminated Soil Leaching Remediation


PAM Dosing and Reaction (Flocculation Reaction Tank)

Dosing Method

Adopt "metering pump dripping" to slowly inject the prepared PAM solution into the flocculation reaction tank at a final dosage of 1-5 mg/L (i.e., 1-5 mg of effective PAM component per liter of leachate). The dosing port is installed in front of the stirring impeller to ensure rapid mixing with the wastewater.

Reaction Control (Two Stages)

  1. Rapid Mixing Stage: Control the stirring speed at 200-300 r/min for 1-2 minutes. The purpose is to achieve instant and uniform contact between the PAM solution and the wastewater, enabling PAM molecules to quickly adsorb onto the surface of colloidal particles.
  2. Slow Flocculation Stage: Reduce the rotational speed to 50-80 r/min and maintain it for 10-15 minutes. This stage is critical for "bridging and agglomeration". Slow stirring can avoid damaging the flocs being formed, allowing small particles to gradually aggregate into large flocs (visible "alum flowers") with a particle size of ≥ 100 μm. Meanwhile, the flocs can adsorb cobalt complexes or free Co²⁺ in the wastewater.

Solid-Liquid Separation (Sedimentation Tank / Clarification Tank)

Process Selection

Due to the high density of the flocs (containing heavy metal precipitates), vertical flow sedimentation tanks or inclined tube sedimentation tanks are adopted, as they occupy less area and have higher separation efficiency.

Operating Parameters

Control the hydraulic retention time (HRT) of the sedimentation tank at 1-2 hours and the upward flow velocity at 1.5-2.5 mm/s. This ensures that the flocs have sufficient time to settle to the bottom of the tank, forming "sludge" (containing heavy metal precipitates, soil colloids, and PAM flocs), while the upper layer becomes clarified liquid.

Water Treatment Field


Polyacrylamide has a good property of flocculation in water treatment. It could help separate the solid and liquid quickly in water and accelerate the sedimentation of solids. The quality of water will improve after polyacrylamide treatment. For wastewater treatment, Polyacrylamide works well with polyaluminum chloride(PAC). Polyacrylamide could work together with PAC to remove the following items from wastewater: chromacity, turbidity, oils,  metal ion, fluoride, phosphate, etc. In addition, the dosage of polyacrylamide could be saved greatly in combination the use of PAC.
