ABSTRACT:
A heat exchange system and process for reducing bleed-off are disclosed employing a weak acid cation exchange resin for treating the aqueous liquid coolant. In one such system and process, the aqueous coolant is treated with a weak acid ion exchange resin to remove alkaline salts therefrom without removing salts of strong acids; suspended solids are removed from the circulating aqueous coolant; and an effective amount of additive selected from the group consisting of scale inhibitors, corrosion inhibitors, microbiocides, and mixtures thereof is introduced into the circulating aqueous coolant so that bleed-off from said system is substantially reduced.
