Understanding Polymer for Thickening and Dewatering Processes - HWEA

Polymer is used as a flocculant for solids separation processes. The aggregation of particles into larger and more removable forms by applying coagulants or flocculants is necessary for efficient separation by clarification, decanting, sedimentation, filtration, thickening, and dewatering processes.

effect of dewatering by the addition of flocculation aid on treated

Effect of Dewatering by the Addition of Flocculation Aid on Treated

There are several sediment dehydration techniques that can be implemented: natural drying, mechanical addition of chemical reagents (flocculation aid/polymer) and thermal drying [18]. Flocculation aids (polymers) are chemicals used in the treatment of waste-water.

Dewatering of inorganic sludge using dual ionic thermosensitive polymers

On the other hand, at pH 9 (Fig. 7 (b)), the polymer is hydrophobic, and the dewatering rate increased as the polymer dosage increased. From these results, it is clear that the hydrophobic transition of the polymer molecules adsorbed on the surface of suspended particles improves the dewatering rate of the drinking water treatment sludge.

Understanding the synergistic mechanism of PAM-FeCl

Electrochemical dewatering enhances solid-liquid separation, and its coupling with chemical conditioning is also an excellent means to further reduce water content. In addition, the improvement of press filter is an effective way, which is influenced by pressure, processing time, sludge cake thickness and pore structure, filter media etc.

Furthermore, the recovered fiber addition successfully lowered the addition of polymer flocculant for dewatering (Table 4) and the water content in dewatered sludge cake (Fig. 4). The systematic evaluation suggests that the adjustment of polymer flocculant and recovered fibers potentially controls the water content in sludge cake irrespective of process configurations in WWTPs.
