Coagulate Waters with Cationic Polymers!

How can polymers coagulate waters with varying zeta potentials?

Which type of polymers is effective in reducing repulsive charges among particles in water?

Answer:

Cationic polymers, carrying positive charges, can coagulate waters with varying zeta potentials by reducing the repulsive charges among particles. They promote coagulation due to their cationic characteristics, and their functionality does not heavily rely on the variance in zeta potential.

In the field of Chemistry, cationic polymers are known to coagulate waters with varying zeta potentials. Zeta potential is the measure of the magnitude of electrostatic or charge repulsion/attraction between particles and is one of the fundamental parameters known to affect stability.

Cationic polymers, carrying positive charges, are widely used in oilfields as water treatment agents due to their ability to reduce the repulsive forces among particles in water, thus promoting coagulation. Their functionality doesn't depend heavily on the variance in zeta potential, understandably due to the interaction of the cationic charge contained in the polymers and negative charge on the particle surface in the waters, initiating the coagulation process.

One such example of a cationic polymer is PolyDADMAC, which is used widely in water treatment processes.
