Packaging Mill Improves Sheet Strength While Reducing Total Annual Treatment Costs by $730,000

GoalImprove packaging sheet strength and reduce treatment costs.

<h6>Customer Challenge</h6> <p>A large packaging mill in South Korea was challenged to improve its sheet strength and reduce its treatment costs.&nbsp; The mill needed to improve white water quality while maintaining a very closed system.&nbsp; The existing ammonium sulfate system was limiting the ability to improve the operation while running the anaerobic digester for waste water treatment.</p> <h6 style="text-align: left;">Recommended Solution</h6> <p>After conducting a thorough audit of the machine, Solenis recommended that the mill convert to Spectrum XD1878 chlorine stabilizer to improve white water quality.&nbsp; This patented technology has the ability to significantly improve operations through better microbial control.</p> <h6>Results Achieved</h6> <p>When Spectrum XD1878 chlorine stabilizer was evaluated on the machine, wet end pH increased from 6.7 to 7.2, which correlated with a drop in microbial activity.&nbsp; Calcium hardness was reduced from 1,400 ppm to 1,000 ppm and conductivity dropped from 3,900 ntu to 3,500 ntu.&nbsp; While the Spectrum program alone was not expected to improve paper strength, the mill realized an increase in ring crush (18%), fold endurance (20%/CD and 60%/MD) and burst (12%) due to reduced starch degradation.&nbsp; Notably, the Spectrum program enabled the mill to reduce its chemical consumption by 23.5% and reduce the total annual treatment costs by $730,000. &nbsp;</p> <p><img style="max-width: 100%; width: auto; height: auto; display: block; margin-left: auto; margin-right: auto;" src="/link/c5a1b760443d4fd88a511a766beb8452.aspx" alt="" width="2390" height="1168" /></p> <p>&nbsp;</p>
