Pulp Mill Significantly Reduces Biofilm Growth and Eliminates Manganese Deposition

GoalReduces biofilm growth and manganese deposition.

<h6>Customer Challenge</h6> <p>A fluff pulp mill was experiencing black supply water and manganese deposition in its machine chests, heat exchangers and pipes. High levels of microbiologically-induced corrosion (MIC) occurred in the heat exchangers and pipes due to uncontrolled biofilm, resulting in increased maintenance and asset replacement costs.</p> <h6>Recommended Solution</h6> <p>Solenis recommended that the mill replace it existing hypochlorite treatment program with ClearPointSM biofilm detection and control program. Comprised of three components&mdash;an OnGuard&trade; 3B analyzer, Biosperse&trade; CX3195 chlorine stabilizer, and Solenis&rsquo; superior service&mdash; the program offers real-time biofouling measurements and automatically adjusts chemical feed to ensure effective, around-the-clock microbiological control.</p> <h6>Results Achieved</h6> <ul> <li>Biosperse CX3195 specificity with microorganisms resulted in a significant reduction in Petrifilm* counts as well as a significant reduction in biofilm thickness and growth&nbsp;</li> <li>Bleach consumption was reduced by 18%</li> <li>Manganese deposition was eliminated in the chests, resulting in increased efficiencies across the mill&rsquo;s critical heat exchangers&nbsp;</li> <li>Heat exchanger efficiency improved, reducing maintenance costs</li> <li>Overall operating costs were reduced by $187,000/year</li> </ul> <p><img style="max-width: 100%; width: auto; height: auto;" src="/link/f3c0284d08ad49faa19172fabd951266.aspx" alt="" width="1100" height="357" /></p> <p>&nbsp;</p>
