Water Soluble Polymer Flocculants: Synthesis, Characterization,

There is no universally accepted formal definition for flocculation, but it is generally accepted that flocculation is the aggregation of solids achieved with the help of high molecular weight polymers through the formation of bridges between particles.

anionic polyacrylamide

ANIONIC POLYACRYLAMIDE

Anionic polyacrylamide is the copolymer of acrylamide and acrylic acid. No studies on the environmental fate of polyacrylamide are available. As a high-molecular weight, water-soluble polymer, it is not expected to biodegrade or bioaccumulate. Anionic polyacrylamide has a low acute toxicity concern to aquatic organisms.

Polymer Flocculants

Polymer flocculants tend to be used in water purification, because polymer flocculants can increase aggregates by gathering components of fine turbidity which cannot sink as it is in the wastewater and can enhance solid¨Cliquid separation from a wastewater.

Fabricating an anionic polyacrylamide (APAM) with an anionic block

Flocculation experimental results demonstrated that the anionic microblocks in the template copolymer could enhance the charge neutralization and bridging ability, and therefore an excellent flocculation performance of treating high turbidity water was observed. 1. Introduction

polyacrylamide - wikipedia

Polyacrylamide - Wikipedia

Polyacrylamide (abbreviated as PAM or pAAM) is a polymer with the formula (-CH 2 CHCONH 2 -). It has a linear-chain structure. PAM is highly water-absorbent, forming a soft gel when hydrated. In 2008, an estimated 750,000,000 kg were produced, mainly for water treatment and the paper and mineral industries.

chapter 7 flocculation with polymers

Chapter 7 Flocculation with polymers

Many polymers used for flocculation are natural in origin (proteins, gums, starch, tannins, and alginates), but recently, synthetic polymers have proved successful, and these are often based on polyacrylamide. They have a range of molecular weight (about 10 5 ¨C10 6) with fairly well defined degrees of anionic, cationic, or nonionic characters.
