This is a GREAT question!
Flocculation happens when a chemical component, such as a cationic polymer, binds to an anionic ionized (dissolved phase) contaminant such as sediment.
So, when our cationic biopolymer is dosed into turbid water with soil or sediment suspended in it from stormwater runoff or equal, the cationic biopolymer binds to the negatively charged sediment particle, flocculating it or moving it from dissolved phase to particulate or solid phase.
Coagulation happens when the flocculated particles agglomerate or "come together" and form even large "clumps" of solid particles.
We have some video footage but are unable to get it uploaded so send us your email please.
