What is anionic polyacrylamide (PAM)?

Anionic polyacrylamide (PAM) possesses interconnected and active groups that establish robust bonds with the surface of suspended colloids, promoting the formation of coarse particles among the suspended solids and a mixture of insoluble particles in water (Irfan et al. 2017).

Does anionic polyacrylamide remove heavy metals compared to FECL 3 and alum?

The comparison revealed that the use of PAC aided by anionic polyacrylamide produced higher removal for COD, TSS and heavy metals compared to FeCl 3 and alum for automotive wastewater treatment. This content is only available via PDF.

What is cationic polyacrylamide (PAM) reagent?

Cationic and multiple-functional polyacrylamide (PAM) are important industrial reagents particularly for wastewater treatment thanks to the excellent flocculation function originating from synergistic effects of charge neutralization and bridging adsorption [ 7 – 9 ].

Can polymers be used with Pac coagulant for ceramic wastewater treatment?

The purpose of this stage of jar-test experiment was to identify the suitable dose of polymers, which could be used in combination with optimal dose of PAC coagulant (300 mg/L) for treatment of the ceramic wastewater. The applied polymer dose varied from 0.5 to 3 mg/L.

Does polymeric aluminum chloride and polyacrylamide dewater sludge?

Sludge dewatering is governed by chemical potential gap depicted by Flory-Huggins theory. Thermodynamic mechanisms of sludge dewatering by chemical conditioning was revealed. This study investigated the combined effects of polymeric aluminum chloride (PAC) and polyacrylamide (PAM) on sludge dewatering, aiming to unveil underlying mechanisms.

How effective are Pac & non ionic polymers for wastewater turbidity removal?

Furthermore, with combination of PAC + anionic + non-ionic polymers, the removal efficiency for wastewater turbidity, TSS, COD and color were 99.93%, 99.94%, 88% and 94.57%, respectively.
