Temperature Resistant Aid Significantly Improves COD and BOD

GoalImprove performance of wastewater treatment plant.

<h6>Customer Challenge</h6> <div>The wastewater pre-treatment system was part of a chemical manufacturing facility. Influent chemical oxygen demand (COD) was 489 &plusmn;79 ppm. The system consisted of an equalization basin, an 800 m&sup3; aeration basin with diffused air; a secondary clarifier and sand filter.</div> <div>&nbsp;</div> <div>COD removal normally ranged from 81- 96%. However, during summer months, the rise in temperature and peak flows were associated with a reduction in COD removal capacity. The loss of performance caused intermittent excursions of COD to above discharge limits.</div> <div>&nbsp;</div> <h6>Recommended Solution</h6> <div>The system was inoculated with Solenis&rsquo; Praestol BA300H, a proprietary blend of temperature resistance bacteria strain designed to improve performance and stabilize the operations of the waste treatment plant.</div> <div>&nbsp;</div> <div> <h6>Results Achieved</h6> <ul> <li>COD in influent stream to wastewater continues to varies.</li> <li>Post treatment of Praestol BA300H, COD in final wastewater effluent decreases.</li> </ul> &nbsp;<img style="max-width: 100%; width: auto; height: auto;" src="/link/a13e11e3cddd43c6aa778ea3fd342567.aspx" alt="" width="1136" height="1720" /></div>
