1, polyacrylamide molecules have positive genes, strong flocculation ability, less dosage, obvious treatment effect.
2. Good solubility, high activity, large volume of alum formed by condensation in water, fast settlement. The purification capacity is 2-3 times that of other water-soluble polymers. 3, strong adaptability, by the water PH value and temperature influence is small, raw water purification to the national reference water standard, after treatment of suspended p...
