<h6 class="PDq2pG_selectionAnchorContainer" data-section-id="1bwnr3y" data-start="0" data-end="25">Customer Challenge</h6> <p data-start="27" data-end="633">A power plant supplies electricity to various locations but had not previously implemented a treatment program for its cooling tower. The softener control was inadequate, leading to total hardness levels of 40–50 ppm. Additionally, vacuum pressure exceeded -0.8 kg/cm² due to scale buildup on the condenser tubes, resulting in issues with heat transfer and steam condensation. To maintain efficient operation, the vacuum pressure needed to be below -0.8 kg/cm², which required reducing the operational load, negatively impacting efficiency. Consequently, the condenser had to be taken offline for cleaning.</p> <h6 class="PDq2pG_selectionAnchorContainer" data-section-id="1gom446" data-start="640" data-end="667">Recommended Solution</h6> <p data-start="669" data-end="867">The power plant turned to NCH Asia Pacific to enhance the cooling tower's productivity and efficiency through sustainable solutions. </p> <h6 class="PDq2pG_selectionAnchorContainer" data-section-id="1k02nyo" data-start="874" data-end="897">Results Achieved</h6> <p>Following the Chem-Aqua Water Treatment System, the results were</p> <ul data-start="899" data-end="1287"> <li data-section-id="kaiw6w" data-start="899" data-end="930">Significant scale reduction.</li> <li data-section-id="xe2wzp" data-start="931" data-end="1016">Stable vacuum pressure below -0.8 kg/cm², eliminating the need to reduce the load.</li> <li data-section-id="159q4gt" data-start="1017" data-end="1082">40% decrease in time, labor, and waste for condenser cleaning.</li> <li data-section-id="13stmov" data-start="1083" data-end="1130">Hardness after softening reduced to < 5 ppm.</li> <li data-section-id="1gii9d7" data-start="1131" data-end="1188">Hardness in the cooling tower maintained below 30 ppm.</li> <li data-section-id="dw3q9w" data-start="1189" data-end="1287" data-is-last-node="">Increased electricity production from 6.5 MW to 8.0 MW, leading to substantial monthly savings.</li> </ul>
