ABSTRACT:
Industrial waters treated with water soluble polymers can be satisfactorily recycled into systems containing hardness causing cations by treating the water containing the polymer with a water soluble persulfate salt. Treated waters may be added, for example, into a recirculating cooling water system, saving makeup water, and decreasing the load placed on industrial plant waste water systems.
