Winter is here, the weather has become cold, the temperature is getting lower day by day, no matter how bad the environment is, our Sewage Water Treatment operation can not be stopped, but in the cold winter will be used as a Flocculant PAM will encounter such and such a problem, these problems affect the use of the effect to a certain extent, plagued the majority of customers.
According to many years of practical experience, our company summarizes the following experience to share with you, I hope to help you.
In winter, the problems affecting the use effect of Polyacrylamide are mainly temperature effects. 1. Lower temperature affects the dissolution speed of Polyacrylamide and the stretching of molecular chain. At room temperature, it takes about 45min to dissolve Polyacrylamide dry powder, high temperature in summer, the dissolution speed will be accelerated accordingly and the dissolution time will be shortened. In winter, the temperature is low, the dissolution speed will be slow, the dissolution time will increase, it is recommended to use Polyacrylamide in winter, the same concentration, increase the dissolution time of Polyacrylamide, so that the Polyacrylamide dry powder can be completely dissolved, so that the molecular chain is completely stretched.
2. Use relatively high temperature water to dissolve Polyacrylamide dry powder, it is recommended to use groundwater to dissolve. Because the temperature of groundwater is relatively high in winter, it can increase the dissolution speed when dissolving . Because the temperature of groundwater is relatively high in winter, it can increase the dissolving speed when dissolving PAM, which can make the polypropylene cool amine dissolve more completely. 3. In winter low temperature, the activity of suspended particles of wastewater is relatively reduced, the adsorption capacity of Polyacrylamide has a certain impact, in this case, you can take to extend the reaction distance between Polyacrylamide and wastewater, increase the reaction time, which can also make the full reaction between PAM and wastewater, to play a better effect.
