Dispersants and Antiscalant Polymers for Water Brenntag

Brennsperse Dispersants help with the free flow of slurries by dispersing the slurry solids to slow or prevent separation. As a result, this yields a more consistent slurry. Four positive things happen when using dispersants in your mining and slurry treatment processes: Drag Reduction: Dispersants reduce turbulence to allow for a more even flow.

Use Sodium Silie as Dispersant in Selective Flocculation
