Removing unwanted particles
Flocculation is the process of removing unwanted particulates (solids) from liquid, which are otherwise difficult to filter or settle out.
When colloidal silica is introduced to a liquid, the liquid becomes destabilized electrically. Solids with opposite surface charges are attracted to the colloidal silica particles, forming clusters or clumps called flocs. These flocs then float to the top (creaming), settle to the bottom (sedimentation), or are readily filtered from the liquid.
Flocculation is common in refractory fiber bonding, the food and beverage, and water treatment industries.
