SNF Factory, Andr¨¦zieux, France. SNF is one of the largest manufacturers of polyacrylamides. These water-soluble polymers are used as flocculants and coagulants in solid/water separation to recycle water, rheology modifiers and friction reducers. These functionalities have many uses where water is used, in drinking water production, wastewater

A recent study financed by SNF-Floerger, has demonstrated that photolysis followed by aerobic or anaerobic treatment resulted in efficient mineralization of the polymer. This study provides evidence that acrylamide polymers have the potential to be naturally broken down and biodegraded and do not persist or accumulate in the environment.

Cationic coagulants neutralize the negative charge of colloidsand form a spongy mass called microflocs. The coagulation mechanism can be summarised in two steps : 1- Charge neutralization : this corresponds to the lowering of the electrical charges that have a repulsion effect on the colloids. 2- Agregation of the particles. 1.1.4. Coagulants:

Impact of Spacer Nature and Counter Ions on Rheological Behavior

Four different polymers and surfactants were used in this work. All polymers were supplied by SNF Floerger (Andr¨¦zieux, France). The concentration of the polymers was fixed at 2500 ppm. The cationic polyacrylamide (FO 4290 SSH) was used with different concentrations of newly synthesized cationic gemini surfactants for rheological measurements.
