The aquaDART system provides real-time monitoring and control of the key parameters that impact corrosion, scale formation, and microbiological growth. At the same time, the treatment chemistry was upgraded to Chem-Aqua 31955, a high-performance corrosion and scale inhibitor designed for systems using highly variable makeup water.</p> <p><img style="display: block; margin-left: auto; margin-right: auto;" src="/link/f39c74b1592c4b8bb54146ceef132519.aspx" alt="" width="505" height="421" /></p> <p><!-- /wp:paragraph --><!-- wp:image {"id":7108,"width":"456px","height":"auto","sizeSlug":"full","linkDestination":"none","align":"center"} --><!-- /wp:image --><!-- wp:heading {"level":5} --></p> <h5 class="wp-block-heading">Results Achieved</h5> <p><!-- /wp:heading --><!-- wp:paragraph --></p> <p>The resulting efficiency improvement has allowed the facility to operate using just one of the two cooling tower systems.
