متداول:
What is the recommended dosage of PAM for heavy metal-contaminated soil leaching?
The recommended dosage is 1-5 mg/L of PAM solution, ensuring effective flocculation and heavy metal adsorption.
How does the two-stage reaction control work in PAM application?
The rapid mixing stage (200-300 r/min for 1-2 minutes) ensures uniform contact, while the slow flocculation stage (50-80 r/min for 10-15 minutes) promotes agglomeration and large floc formation.
What type of sedimentation tank is best for PAM-treated leachate?
Vertical flow or inclined tube sedimentation tanks are ideal due to their high separation efficiency and compact design.
What are the key benefits of using PAM in heavy metal soil remediation?
PAM enhances solid-liquid separation, improves water clarity, and effectively adsorbs heavy metals, making it a reliable solution for soil remediation.
