controlling flocculation

What does this part of my lecture slides mean: 'can be controlled by addition of flocculating agents like surfactants (ionic-zeta potential and nonionic bridging) & polymers (bridging, also increases viscosity). Polymers affect velocity'

I especially don't understand the parts in brackets as it lacks detail, can someone please expand?

I'm just wondering why you cannot email your professor the same exact question you've posted above ?? 🙂
