Cooling water is circulated through copper lines directly mounted on the walls of the furnaces, which are typically only operated 12 hours per day.</p> <p><!-- /wp:paragraph --><!-- wp:paragraph --></p> <p>The makeup water is very corrosive with very low hardness and alkalinity levels. The cooling tower system has a very long half-life due to the relatively low evaporation rate and large system volume. The cycles of concentration are kept low to prevent stagnation problems associated with the extremely long half-life. With an LSI of - 1.0, the tower water is also very corrosive.</p> <p><!-- /wp:paragraph --><!-- wp:paragraph --></p> <p>Legacy water treatment program employed an industry standard stabilized phosphate corrosion inhibitor. Supplemental copper inhibitor was required due to large amount of copper piping. The use of zinc and other heavy metals was prohibited by environmental regulations.
