Cooling water treatments are applied to concentrated waters in laboratory cooling towers. Chromate and non-chromate corrosion inhibitors are utilized to maintain corrosion control. Effective scale inhibitors allow for expanded solubility limits at elevated TDS levels and minimized fouling of heat exchanger surfaces. Both neutral pH and high alkalinity programs are applied. Two related case studies are presented.
