Zwitterionic High Viscosity Polyacrylamide for Municipal Sludge in Portugal

The first ion exchangers were based on synthetic resins of high hydrophobicity and low porosity, suitable for exchange of small molecules, such as inorganic ions, organic acids, and amino acids. Due to their hydrophobicity and high charge density, these matrices were not suitable for separation of biological samples.

Mechanism of flocculation of polyacrylamide. PAM has two characteristics: a long chain (line) - like molecular structure and a large number of active groups. PAM is straight chain polymer, because each molecule is composed of more than one hundred thousand monomer polymerization, the molecular chain is quite long.

For most polymer-thickened systems, the viscosity–shear rate plot displays a high viscosity Newtonian plateau at low shear (typically at shear rates 1/s), a shear-thinning region (at shear rates ⬃1–102/s) and a low viscosity plateau at high shear ( 102/s). The magnitude of the viscosity at low shear determines the suspending properties.
