chapter 7 flocculation with polymers

Chapter 7 Flocculation with polymers

FLOCCULATION WITH POLYMERS 7.1 INTRODUCTION For several decades both natural and synthetic water soluble polymers have been used as flocculents, dispersants, thickeners, flotation depressants, filtration and settling aids throughout a wide range of industries (i.e. mineral, paper, effluent, textile, food). This versatility is due to the fact

influence of surfactants on flocculation and dewatering of kaolin suspensions by cationic polyacrylamide (pam-c) flocculant

Influence of surfactants on flocculation and dewatering of kaolin suspensions by cationic polyacrylamide (PAM-C) flocculant

Cationic polyacrylamide (PAM-C) of molecular weight 6¨C7¡Á10 6, charge density 150 C/g and cationicity of 19% has been used as the flocculating agent. The surfactants used in this work are anionic SDS, cationic CTAB and non-ionic TX 100, and were supplied by Sigma chemicals, and Merck, Germany.

Spotlight on the Life Cycle of Acrylamide-Based Polymers Supporting Reductions in Environmental Footprint: Review and Recent Advances

Polyacrylamide copolymers, either anionic or cationic, are potentially quickly converted to corresponding polyacrylate salts by deamination or hydrolysis. Therefore, biodegradation of related polyacrylic acid (or related salts) provides insights in polyacrylamide biodegradation and their fate.
