Charge density flocculation parameters

The influence of several parameters related to the characteristics of the solid materials (e.g., charge, particle size), the polyelectrolyte (e.g., type of charge, charge density, molar mass, hydrophobicity) and the flocculation regime (e.g., order of additimi, pH, imiic strength) are discussed. 

Research in this area shows great potential. Over the past 30 years, dual systems have been applied mainly in the paper industry. The applicatimi of PECs, described as particle-forming flocculants, provides new possibilities in solid-liquid separation processes. For an effective system, the application parameters have to be optimized (e.g. polymer type, cmicentratiOTi, charge, molecular weight). Therefore, direct and efficient methods for the characterization of the flocculation behavior (sedimentation velocity, packing density of the sludge, particle size distribution) are necessary and will be described.
