Anionic Polyacrylamide Chemicals Flocculant Water
Anionic polyacrylamide (APAM) series products are water-soluble linear polymers synthesized under high degree polymerization, easily soluble in water, almost insoluble in the benzene, the ether, the aliphatics, the acetone and other common organic solvents. At the meantime, APAM series products also have valuable properties like the flocculation, the thickening, the shear property, the drag-reduction and the dispersibility etc., thus widely used in the oil recovery, the mineral processing

Anionic polyacrylamide - wastewater treatment chemicals
Anionic polyacrylamide is the kind of wastewater treatment chemicals which is water-soluble linear polymer synthesized with high degree of polymerization. Anionic polyacrylamide powder is easily soluble in water and almost insoluble in common organic solvents such as benzene, ether, lipids and acetone. Anionic polyacrylamide molecular chain contains a certain amount of polar groups capable of adsorbing suspended solid particles in water, so it is especially suitable for water treatment with

Flocculation of hematite fines by anionic polyacrylamide
Flocculation studies on iron-ore fines (size < 10 μm) were conducted using three anionic polyacrylamide polymers over the pH range 4.0–10.0 and flocculant dosages up to 0.20 kg/ton.The flocculation was favourable under acidic conditions and was helped substantially by CaCl 2 additions in alkaline conditions. Zeta potential measurements indicated a specific adsorption of polymers.

The effective PH value range to the anionic polyacrylamide is 5 ~ 14, the effect is good in the treatment of the weak acid, the neutral and the alkaline water. The effective PH value range to the cationic polyacrylamide is 7 ~ 14, the effect is good in the treatment of the neutral and alkaline water. The effective PH value range to the nonionic polyacrylamide is 1 ~ 8, the effect is good in the treatment of the neutral and acid water.

What is Polyacrylamide? | SNF
Polyacrylamide, or PAM, is an organic polymer formed from acrylamide sub-units. Initially, it is produced with a simple, repeating, linear chain structure, but can be modified to form highly structured, branched and cross-linked variants. It has many uses throughout a wide range of industrial processes, but one of the main purposes is in the...

Influence of surfactants on flocculation and dewatering
It exhibits point of zero charge at pH 2.2. Cationic polyacrylamide (PAM-C) of molecular weight 6–7×10 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.

Indeed, it has been reported that anionic polymers are poor flocculants for `pure' clays in pure waters. Anionic polymers in the lresence of inorganic cations, e.g. Mg +, A13+ and Fe + are quite effective flocculants. Also, starch-based and non-ionic synthetic polymers perform best in the presence of metal ions.
