When it comes to cationic polyacrylamide, we all know that it can be used for sludge dewatering. Then the petrochemical industry produces a large amount of wastewater sludge, which is mainly treated by enterprises for landfill, but it can easily cause secondary environmental pollution. Can cationic polyacrylamide be dehydrated and then treated?

Everyone knows that our main goals for sludge treatment are to achieve: harmless, stable, reduced, and resourceful.Everyone can choose cationic polyacrylamide treatment.

We generally use polyacrylamide and polyaluminum chloride to treat sludge.Therefore, cationic polyacrylamide is selected for dehydration of petrochemical sludge with good effect.Precautions when dewatering sludge：

1. The effect of sludge dewatering is to remove a large amount of water from the sludge, reduce its volume and reduce its weight.；

2. Generally, after dehydration and drying treatment, the water content of the sludge can be reduced from about 90% to 60~80%, and the volume is reduced to only 1/10~1/5 of the original.
