Polyelectrolyte determination in drinking water

Polyelectrolyte determination in drinking water

South Africa have adopted these polyelectrolytes as part of their water treatment process (Leopold, 2004). Polyelectrolyte products used in the water supply industry may contain in addition to polyelectrolyte, measurable amounts of certain contamits. These contamits are essentially un-reacted raw material from the polyelectrolyte ...

a strongly cationic organic polyelectrolyte Because metal hydroxides form precipitates, only dual-media filters should be used with inorganic coagulant programs. Floc particles must be handled in filters with coarse-to-fine graded media to prevent rapid blinding of the filter and eliminate backwashing difficulties.

The cationic polyelectrolytes commonly used as primary coagulants are polyamines and poly-(DADMACS). They exhibit strong cationic ionization and typically have molecular weights of less than 500,000. When used as primary coagulants, they adsorb on particle surfaces, reducing the repelling negative charges.
