Jun 17, 2014 · 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 …

Feb 08, 2021 · Polyacrylamide is the collective name for thousands of organic polymer electrolytes with acrylamide as the main component. Cationic polyacrylamide (CPAM) is commonly used for dewatering because sludge particles are usually negatively charged. The efficiency of sludge conditioning depends on CPAM and sludge characteristics.

The effect of cationic salt addition on the settling and dewatering properties of an industrial activated sludge - Novak - 1998 - Water 1/7/1998 · An industrial activated‐sludge treatment plant was studied to determine whether variations in settling and dewatering properties of the mixed liquor and waste solids could be caused by changes in ...

The membranes MWCO was measured with PEG as testing solute dissolved in DMF. MWCO values of 50 kg mol –1 at room temperature and 100 and 105 kg mol –1 at 80 and 100 °C, respectively, were obtained. It is possible that the PEG coil dimension changes with the temperature, due to changes of the enthalpic interactions between PEG and DMF.
