Coagulation destabilises the charges of tiny particles suspended in water, which often have negative charges, causing them to repel one another and remain dispersed.
Coagulants work by balancing out these negative charges, allowing the particles to combine and form larger, more readily removable aggregates.
Monomer & Poly DADMAC: Low-molecular-weight, high-charge-density cationic polymers that neutralise surface charges on ultra-fine or colloidal particles, promoting micro-floc formation.
