Which is better cationic or anionic polyacrylamide?

Cationic PAM is especially suitable for treating negatively charged organic substances such as high-concentration colloids and suspended solids in wastewater treatment. Due to its complex production process and superior performance, cationic PAM is usually priced higher than anionic polyacrylamide.

Can cationic polyacrylamide flocculants be used in river water?

The amount of flocculant added is 1/50 of that of inorganic flocculants, but the effect is several times higher than that of inorganic flocculants. For river water with severe organic pollution, it is better to use inorganic flocculants in conjunction with cationic polyacrylamide flocculants.

What is cationic polyacrylamide (CPAM)?

Cationic Polyacrylamide. In general, CPAM is white powder in appearance with an ionic degree ranging from 20% to 55%. It has the characteristics of high polymer electrolyte and is suitable for the treatment of wastewater with negative charge and rich in organic matter.

Is Pam a water soluble polymer?

The polyacrylamide flocculant (PAM) is a linear water-soluble polymer and is one of the most widely used types of water-soluble polymers. PAM and its derivatives can be used as efficient flocculants, …

Can polyacrylamide flocculant improve water purification capacity?

Using organic polyacrylamide flocculant instead of inorganic flocculant, even don’t modify the sedimentation tank, it can increase water purification capacity by more than 20%. In sewage treatment, the use of PAM flocculant can increase the utilization rate of water recycling and can also be used for sludge dewatering.

What is Pam flocculant used for?

In sewage treatment, the use of PAM flocculant can increase the utilization rate of water recycling and can also be used for sludge dewatering. In industrial water treatment, it is an important formulation agent. PAM polymer is a kind of multifunctional oilfield chemical treatment agent.
