saline water management (brine treatment) in industry at germany
As a result, when most of the water is removed during dewatering, the partially degraded proteins and polysaccharides present in the sludge will form gels that hold water. Thus, the cationic polyacrylamides would only have a minimal effect on removing water from the gel formed by the TB-EPS around the sludge particles.
When the amount of cationic monomer was increased from 10 to 55mol% in solution polymerization, hydrophobic contraction of the core induced formation of more compact C-PAMs. The copolymers prepared using emulsion polymerization formed highly aggregated or supercoil structures owing to increased intermolecular hydrophobic interaction when less cationic monomer was used.
