Treatment of pulp and paper mill wastewater by polyacrylamide (PAM) in polymer induced flocculation

Cationic polyacrylamide Anionic polyacrylamide 1. Introduction The pulp and paper industry is a very water-intensive industry and can consume as high as 60 m 3 of freshwater per tonne of paper produced [1]. The generation of wastewater and the characteristics of pulp and paper mill effluent depend upon the type of manufacturing process adopted.

mechanistic insights into chemical conditioning by polyacrylamide with different charge densities and its impacts on sludge

Mechanistic insights into chemical conditioning by polyacrylamide with different charge densities and its impacts on sludge

In this study, we therefore investigate the mechanisms of sludge conditioning with a widely used organic flocculant, polyacrylamide (PAM), by using a suite of time-resolved characterization technologies.

Preparation of octopus-like lignin-grafted cationic polyacrylamide flocculant and its application for water flocculation

Compared with commercial linear cationic PAM with ultra-high molecular weight (7000¨C10,000 kD) and high cation degree (2535%), the hyperbranched cationic PAM possessed lower molecular weight (2000¨C3500 kD) and less cationicity (10¨C25%), but the flocculation efficiency was comparable or even better, attributing to the hyperbranched chain microstr...

Biodegradation of Polyacrylamide and Its Derivatives | Environmental Processes

The monomer acrylamide is toxic to most microorganisms, however, some bacteria and fungi could degrade it using amidases that deaminate acrylamide to acrylic acid and ammonium, and further utilize acrylic acid to produce CO 2 and water. Some fungi and yeasts could degrade 60¨C80% of acrylamide.
