Polyferric sulfate and polyacrylamide are commonly used water purification flocculants at present. Can these two agents be used at the same time? Will polyferric sulfate and polyacrylamide react when used at the same time?
Polyferric sulfate is an efficient water purification flocculant. Its main function is to flocculate the small substances in the sewage together and then precipitate to the bottom, so as to purify the water source.
Polyacrylamide is a high molecular flocculant. Its function is to make the flocs in sewage larger and accelerate the sedimentation of flocculated particles in sewage.
From the effects of these two agents, we can conclude that polyferric sulfate and polyacrylamide can be used together, and the effect will be better when used together. When they are used together, there will be no chemical reaction!
However, it should be noted here that in the dosing sequence when polyferric sulfate and polyacrylamide are used together, the two agents cannot be put into the water at the same time, which can not achieve good results. So, which one should you put polyferric sulfate and polyacrylamide first?
From their action principle, polyferric sulfate should be put into coagulation first, and then polyacrylamide should be put into accelerated sedimentation. When the small particles in the water are too small, polyacrylamide should be put into coagulation first, and then polyferric sulfate.
Can polyferric sulfate and polyacrylamide be used together? The answer is yes. Just pay attention to the delivery order when you use it.
