Effects of various fillers on anionic polyacrylamide systems for treating kaolin suspensions

1. Introduction Recently, synthetic polyelectrolytes, particularly anionic polyacrylamide (A-PAM), have been widely used as flocculants in wastewater treatment due to their efficiency, the reduced cost of chemical usage, and the smaller quantity required [1], [2], [3].

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.

Acrylamide and polyacrylamide (PAM) are used in diverse industrial processes, mainly the production of plastics, dyes, and paper, in the treatment of drinking water, wastewater, and sewage. Besides inorganic form, acrylamide is formed naturally in certain starchy foods that were heated to cook a temperature above 120 ¡ãC for elongated time.

Polyacrylamide

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. [1] Physicochemical properties [ edit]

Polyacrylamide, as an organic polymer flocculant, was widely used in the flocculation treatment of mineral processing wastewater and tailings. In this paper, the types of polyacrylamide commonly used in flocculation of wastewater generated from the beneficiation of metal ore, oil sand and phosphate ore were summarized. 1. Introduction
