Unlike suspended solids that settle under gravity, scale forms through chemical precipitation directly on surfaces.<\/p>\n<p>The <strong>Water Research Foundation<\/strong> estimates that scaling costs U.S. industries <strong>$2.1 billion annually<\/strong> in energy losses, equipment damage, and maintenance expenses.

Temperature Elevation<span class=\"ez-toc-section-end\"><\/span><\/h4>\n<p>Temperature profoundly affects scale formation because carbonate solubility decreases exponentially with increasing temperature. Heat transfer surfaces in boilers, heat exchangers, and cooling tower tubes experience the most severe scaling.<\/p>\n<p>According to <strong>GE Power<\/strong>, every <strong>25\u00b0C increase<\/strong> in surface temperature doubles the calcium carbonate precipitation rate.
