- Granular polyacrylamide flocculant can not be used in the sewage directly. It must be dissolved in water before use, with its solution to sewage treatment.
- Dissolving water shall be clean water ( tap water), not sewage. Room temperature is Okay. Generally speaking, when water temperature is below 5 ℃, PAM dissolves very slow. When the temperature is more than 40 ℃, it will accelerate the degradation of the polymer, affect the results. Usually tap water is suitable for the preparation of a polymer solution. While Acid, alkali, high salt water is not suitable for preparation.
- Polymer solution concentration: 0.1% -0.3%, ie.1 g-3g polymer powder for 1 liter of water.
