Can anionic polyacrylamide be used in water treatment?

What's more, the authors discussed the application status of anionic polyacrylamide in water treatment. Based on these reviews, future research perspectives relating to its synthesis and application were proposed. This review summarizes the synthesis methods for anionic polyacrylamide.

Can anionic polyacrylamide be used as coagulant aid with ferric sulphate and polyaluminium chloride?

It is important to point out that the optimal coagulant dose can be reduced when anionic polyacrylamide is used as coagulant aid with ferric sulphate and polyaluminium chloride, thus decreasing treatment costs. 3.10. Mechanisms of the process

Does anionic polyacrylamide improve the coagulation–flocculation process?

The use of anionic polyacrylamide had little effect on this cost but improved the coagulation–flocculation process, leading to a significant increase in the settling speed and reduction in the volume of sludge produced. Table 7.

What are the different types of polyacrylamide adsorption?

In practice, however, this adsorption is often enhanced by using modified (anionic or cationic) forms of polyacrylamide. Polyacrylamide can be classified to three categories: non-ionic, anionic and cationic polyacrylamide. Keywords: Polyacrylamide; non-ionic; anionic; cationic; wastewater treatment. 1. INTRODUCTION

What is polyacrylamide used for?

Polyacrylamide (PAM) is a collective term for polymers obtained by the homopolymerization or copolymerization of acrylamide monomers under the action of an initiator. It can be used as a coagulant, retention aid, sludge dewatering agent, and flocculant sedimentation agent, among other uses, and has a wide range of applications.

What is the coagulation speed of anionic polyacrylamide?

Coagulation speed: 200 rpm. Flocculation speed: 20 rpm when the coagulant was used alone and 40 rpm when anionic polyacrylamide is added, since the flocs formed were larger and heavier and tended to settle at the lower speed. The influence of the settling time was also studied, the duration of the experiments being fixed at 60 min in all cases.
