Why does the amount of cationic polyacrylamide affect the therapeutic effect

Cationic polyacrylamide is used in sewage treatment. We all know that this product has good flocculation effect and coagulation effect, but its type is more complex, not every type is suitable for various sewage properties. In the selection, it is necessary to conduct experiments according to the nature of sewage in the application industry, and choose the appropriate type and dosage. The process of using cations in sewage treatment is also important. The product itself is easily soluble in water, molecular weight has little effect on water temperature.

The solubility of cationic polyacrylamide is generally recommended to be 10%. More than 10 percent will appear gel, affecting the use of sewage treatment. When dissolving, the dissolution temperature can be appropriately increased to accelerate the dissolution rate, but the water temperature should not exceed 60 degrees, otherwise the product will be degraded due to the high dissolution temperature, affecting the treatment effect.

And clients often ask why the amount of cationic polyacrylamide can affect the effectiveness of treatment. pH has a great influence on the effectiveness of the product. Generally in neutral and alkaline conditions will highlight the effect, in acidic conditions can not play a role.

Secondly, the suspended matter in the water is very small and gelatinous. It is necessary to add coagulant or coagulant aid first, and then add cationic polyacrylamide flocculation to achieve good treatment effect.

Third, if the treatment effect of the above method is still not ideal, it is necessary to consider replacing other ionic polypropylene. Through the above description, we can clearly know that the effect of cationic polyacrylamide depends on many factors, so in use, first of all, through the experiment to choose the appropriate model and dosage, if the effect is not stable, and then make some adjustments.
