This experiment systematically evaluates the treatment performance of different flocculants under identical water quality conditions to provide theoretical basis and data support for practical application.
Specific goals:
(1) Compare suspended solids removal efficiency of different flocculant models;
(2) Determine the optimal flocculant and its effect on settling velocity. The experimental design supports flocculant selection and process control in water treatment engineering.
Settling Test & Data Recording
During static settling, the following indicators were recorded: (1) settling time; (2) settling velocity; (3) supernatant clarity; (4) underflow sludge compactness.
Results & Discussion
1. Test conditions: Ore slurry parameters, pH 5.6, flocculant dosage 1 mL.
2. PAM test data
(Note: Lower underflow compactness percentage indicates denser sludge)

From the above data, it can be seen that when the dosage of our PAM6103 is 1 ml, its flocculation effect is the best.
At pH 5.6, comparing different flocculants for treating same-turbidity water at a dosage of 1 mL, PAM6103 and the on‑site PAM showed advantages in settling velocity and compactness. Therefore, anionic polyacrylamide 6103 significantly outperforms the currently used flocculant in flocculation performance.
