Beverage Clarification & Water Treatment

In beverage clarification applications, colloidal silica is used as a functional-processing aid for removing undesirable components from liquids. Selection of the appropriate colloidal silica is critical for achieving processing goals.

One of the processes employed for the removal of fine particulates from liquids is flocculation. This process causes precipitates, called flocs, to float to the top (“creaming”) or settle to the bottom (“sedimentation”) of a liquid. In both cases, flocs can be easily removed or filtered out.

In beverage clarification, negatively charged colloidal silica particles are used in combination with gelatin and/or bentonite to flocculate undesirable proteins, yeast particles and pectin suspended in raw beverages. The resulting precipitates are then removed, improving the taste, appearance and shelf life of the final beverage.

Precipitation is a process often confused with flocculation. Precipitation is the separation of dissolved contaminants, while flocculation is the separation of suspended contaminants.
