How to formulate polyacrylamide PAM into liquid, and its turbidity, decolorization, including the application of removing heavy metal ions, polyacrylamide PAM in the process of dosing and use, how to choose its dosage ratio through the situation of wastewater, which is very important. Under normal circumstances, wastewater is collected for small experiments to calculate the amount of polyacrylamide PAM.
　　
In the process of using polyacrylamide PAM, we often use emulsion polyacrylamide PAM, so we need to formulate it into an aqueous solution of 1% to 5%, with an exception to this, when the turbidity of the raw water is very high, it can be directly dosed. If solid polyacrylamide PAM is used, we should formulate it into 0.1% to 0.5% aqueous solution for dosing, and then according to the specific situation, the prepared solution is put in according to the best conditions and dosage, so that the dosing method can make the polyacrylamide PAM achieve the best flocculation effect. So how do we dilute the polyacrylamide PAM concentration based on turbidity? Through experiments, we obtained that if the general turbidity (turbidity is 100-500mg/L) water, polyacrylamide PAM 30-50 kg per thousand tons of wastewater is used. The approximate specific weight-to-weight ratio is 1:3.

Polyacrylamide
　　
Sewage treatment enterprises generally dilute 2-5 times when using polyacrylamide PAM, and then dosing treatment. According to the nature of the raw water nature, the concentration of pollutants, the phenomenon of alum flower formation is appropriate, basically can be achieved under the same water quality situation.
