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.

Why are non ionic and anionic polyacrylamide based flocculant chains used in tailings treatment?

Non-ionic and anionic polyacrylamide (PAM)-based flocculant chains are commonly employed in a vast majority of tailings treatment operations and several studies have been conducted on degradation of PAMs due to various factors such as pH, light and temperature , microbial degradation and chemical degradation .

Does ultrasonication affect the degradation of polyacrylamide-based flocculants?

The effect of ultrasonication, screening and shearing on five polyacrylamide-based flocculants of similar molecular weight but different degrees of anionicity (DA) was studied through measurement of intrinsic viscosity ( [η]) and size exclusion chromatography (SEC) to investigate the influence of DA on the degradation of polymers.

What is non ionic polyacrylamide flocculant used for?

Dissolving non-ionic polyacrylamide flocculant into a concentration of 0.3% and adding it to a crosslinking agent can play a role in sand control and consolidation when sprayed on the desert. Soil moisturizing agent It used as a soil moisturizing agent and the basic raw material for various modified polyacrylamide flocculants.

What is polyacrylamide (PAM) used for?

In water treatment and industrial production, polyacrylamide (PAM) is widely used as an important flocculant in wastewater treatment, pulp production, ore processing, and other fields. Based on its ionic properties, PAM can be divided into anionic polyacrylamide (APAM) and cationic PAM (CPAM).

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.
