What is the difference between polyacrylamide and polyaluminium chloride in use

Polyaluminium chloride and polyacrylamide are commonly used in water treatment, both of which have the function of sewage treatment. What are their different effects and functions in sewage treatment, and why are they divided into two different types?

Polyacrylamide is an organic flocculant, also known as PAM. Polyacrylamide is mainly used in sewage treatment, raw water treatment and industrial water treatment. In sewage treatment. Polyacrylamide can be used for sludge dewatering. In raw water treatment, polyacrylamide can be used together with activated carbon to agglomerate and clarify suspended particles in living water. In industrial water treatment, it is mainly used as a prescription agent. PAM can increase the utilization rate of water recycling cycle in sewage treatment. In raw water treatment, organic flocculant PAM is used instead of inorganic flocculant, and the water purification capacity can be increased by 20% without modification of settling tank. At present, PAM supplements the shortage of water supply or poor water quality in many large and medium-sized cities.

Polyaluminium chloride is an inorganic flocculant with good effect in sewage treatment. It has a wide range of applications and is widely suitable for various water types. It can form alum quickly and has good sedimentation property. The suitable PH value range is wide, and the PH value and alkalinity of treated water decrease slightly. When the water temperature is low, the stable sedimentation effect can still be maintained. Alkalinity is higher than other aluminium and iron salts, and it has little effect on equipment erosion. But polyacrylamide is still widely used in sewage treatment. It can be said that polyacrylamide is more used in sewage treatment. It is also possible to treat water with PAC because they are different types of flocculants, so they can be used complementarily and in combination with each other, far more effectively than using a single product.
