Coagulant/flocculant polymers

There is a very wide range of coagulant/flocculant polymers. Typical organic... [Pg.48]

There are a number of major, international manufacturers of coagulant and flocculant polymers whose primary markets are high-volume users (i.e., cities, states, and national governments). There are also many smaller regional manufacturers who tend to specialize in niche markets and produce various polymer blends (organic polymers blended with various ratios of inorganic coagulants such as ACH, PAC, and alum). These polymer blends are particularly useful in industrial facilities where process contamination and difficult clarification problems may exist. [Pg.318]

As mentioned previously in Section 7.2.4, the coagulation/flocculation process was found to be affected by the presence of surfactants in the raw water or wastewater. Such interference was observed for both alum and ferric sulfate coagulant, but the use of certain organic polymer... [Pg.347]

Tn general, the removal of particulate matter in water and wastewater via coagulation/flocculation with cationic polymers occurs in three steps ... [Pg.329]

Additionally, in this filtration process no flocculating polymers at all are needed to the exclusive benefit of the organic coagulant. Velocities are from 10 to 18 m h". ... [Pg.90]

Lime and ferric are used as coagulants and polymer used as flocculant. Quantity used is Lime 1500-2000 ppm Ferric 750-1500 ppm Polymer 1-2 ppm Acid Depending on pH Hypochloride 50-100 ppm... [Pg.108]

The product obtained from (conventional) emulsion polymerization is a colloidal dispersion comprising a very large population of submicron hydrophobic polymer particles dispersed in the continuous aqueous phase. This colloidal system is not thermodynamically stable because of the incompatibility between polymer and water (i.e., the very low solubility of polymer in water) in nature. As a matter of fact, the fate of most common latex products is the coagulation of polymer particles in order to minimize the particle-water interfacial area. Moreover, the monomer-swollen particles may even lose their colloidal stability and flocculate with one another in the course of emulsion polymerization. This will inevitably make the particle nucleation and growth mechanisms more complicated. [Pg.11]
