metallurgical waste water treatment by pam chinafloc
High molecular weight (106–3 × 107 Da) polyacrylamide (PAM) is commonly used as a flocculant in water and wastewater treatment, as a soil conditioner, and as a viscosity
The polyacrylamide dosages required to achieve measurable flocculation decreased as the flocculant age was increased, with optimal performance attained at 72 h. Flocculation using a 1-h-old
