Preparation, Characterization, and Sludge Conditioning of

The sludge conditioning performances of NP and SP were comparatively evaluated, and the mechanism was determined by examining sedimentation behavior and floc size distribution. High intrinsic viscosity, porous morphology structure, and mixed NP cationic homopolymer contributed to the improvement of sludge conditioning performance.

Characterization and sludge dewatering performance evaluation

The sludge supernatant after flocculation and conditioning process was extracted from the beaker 1 cm below the solution surface for determining zeta potential and residual turbidity. The settled sludge was poured into a Buchner funnel, and the vacuum pump was started to conduct suction filtration with a vacuum degree of 0.06 MPa.

Municipal Sludge−Industrial Sludge Composite Desulfurization

Mixtures of sewage sludge, waste oil sludge, and metal oil sludge were prepared and carbonized at 950 °C in an inert atmosphere. Dynamic adsorption of H2S was measured on the materials obtained, and the breakthrough capacity was calculated. The initial and exhausted adsorbents after the breakthrough tests were characterized using sorption of nitrogen, thermal analysis, and XRF, XRD, and

Study on pore characteristics of flocs and sludge

After conditioning 45 s (flocs forming stage), a dewatering step can be applied to remove the water contained in sludge and shorten the time. Abstract To study the influence of floc characteristics on dewatering performance of excess sludge, a fractal method is adopted to characterize the sludge flocs formed at different flocculation time.

UV-Initiated Polymerization of Hydrophobically Associating

Two cationic polyacrylamides, PAA and PAD, were synthesized for sludge dewatering. The advanced instruments such as 1H NMR, FTIR, and SEM were used to characterize the two copolymers. Their hydrophobic association properties in water were investigated by viscosimetry as well as the dewatering performance studied by the sludge dewatering experiment.
