cationic polyacrylamide (cpam) enhanced pressurized vertical
pressurized vertical electro-osmotic dewatering (pveod) has been regarded as a feasible method to achieve sludge deep-dewatering, but the dewatering efficiency is still challenged by high electric resistance. this study employed cationic polyacrylamide (cpam) as a skeleton builder to enhance electro-osmotic flow in pveod.
cationic polyacrylamide synthesis and application in sludge,cationic polyacrylamide (cpam) were used extensively in water treatment, enhanced oil recovery and sludge dewatering. the review summarized the synthesis methods research progress of cationic flocculants. four groups of synthesis technologies of cationic copolymers were reviewed, including aqueous solution polymerization, dispersion polymerization, inverse emulsion polymerization and photo
research on a new cationic polyacrylamide (cpam) with high purity
the cationic monomers on these microblock segments can be polymerized to form a cpamd with a new cationic microblock structure. in addition, microwave has mechanical effects such as oscillation, emulsification, and diffusion, which can accelerate the heat and mass transfer process of the reaction system, thus accelerating the reaction rate (wiesbrock et al. 2004; hoogenboom and schubert 2007
