A water containing 10 mg/L of DOC and 20 mg/L of clay particles is to be destabilized using a cationic polymer that has a charge density of 6 meq/g-active polymer. The polymer is supplied as a 50% by weight aqueous solution. Assume that the negative charge densities of the natural organic matter and the clay particles are 10.0 and 1.0 meq/g, respectively.

Calculate the required dose of the polymer solution (as purchased) to achieve destabilization by charge neutralization
