flocculation

The performance of polyelectrolytes can be modified to suit the nature of the colloidal material that is to be removed from a water, by altering the molecular weight and ionic nature of the polymer. Some of these modified polyelectrolytes are rather expensive and are very sensitive to changes in the chemistry of the water being treated.

Above, a pictorial representation of the action of polyelectrolyte chains upon particles suspended in water.

The elevated particle charge produced by the Zeta Rod™ causes enhanced reactivity of synthetic polyelectrolytes, allowing the use of a less expensive, less sensitive, or less specific formulation in some applications with increased efficiency.

Enhanced flocculation with the Zeta Rod™ has been demonstrated in process water clarification, centrifugation of sanitary sewer sludge, flocculation of metal hydroxides in a planetary wastewater, and enhanced flocculation of fines in a secondary fiber papermill wastewater system.

ZETA CORPORATION has been notified that a patent application by Zeta describing such electrostatically-enhanced reactions is being allowed.
